[Flightgear-devel] Flap position
Hi, I am trying to model the A320 flaps. I has 5 positions but in the keyboard or joystick bindings, each time I hit the flap down button, /controls/flight/flaps is increased by rawly 1/3, leading to only four possibilities. Would it be possible to make the increment aircraft dependant, instead of global ( I need here of a 0.25 increment ) ? -Fred ___ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel

This property is the output position of the flaps from the fdm and I use it for the 3d model. The problem is with the command bound to keyboard or joystick that only allow 4 input position ( inherited from the c172 I presume ) -Fred ___ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
[Flightgear-devel] 747 Panel Feedback
A few comments, after playing with the 747 panel a bit more. Firstly, I'd just like to say how amazing it is, given the non-impact on the frame-rates, smoothness and clarity of the text, and so on. It's just lovely. Now, on with the nit-picking. Note many things I'm going to suggest probably require some level of C++ coding (even if it's just exposing more properties), and given sufficient arm-twisting I might even look at them myself. I've looked over the panel files, but I find the relation between the 3d models and the panel a bit hard to grasp... Also note my 'experience' is based on the PMDG 777 for Fly!, but I assume Boeing glass cockpits don't vary much. - The PFD auto-pilot annunciation is lacking supported for armed modes (in white, rather than green text). Eg, when in heading mode, and engaging a NAV mode to intercept a VOR radial, NAV should be displayed in white above (below?) the still-green HDG until the radial is intersected. And the more common case, in V/S mode, heading towards a commanded ALT, ALT should be displayed in white. The whole reason I'm writing this is because I subconsciously found it very disturbing to enter a target altitude and not see ALT there in white (I've obviously spent way too much time with the PMDG 777 in Fly!). - The speed trend indicator bar is missing; obviously this requires code and probably FMS interaction to be accurate, though I suspect a first order approximation [trend-velocity = velocity + (current_acceleration * 5.0)] would be enough. Again, it wasn't till I sat and thought about this I realized it was missing, but it made my flying much worse (on a manual throttle) And now a couple of 'please's - I really need a visual indicator of flap position, either the lever itself or the EFIS page showing the flap 'bar'. And related to that, is the 747 missing some detents? I'd expect 1,2,5,10,15,25 (and maybe 40?). It seems like there's only three detents at the moment, and I keep ballooning on approach picking the wrong one. [anyone who points out a good visual indicator of flap position would be switching to the external view gets a sullen look from me] Oh and, if we're being clever, updating the safe Vmax marker on the speed-tape based on the current flap setting would be wonderful (yes, I'm a lazy person who uses that to schedule flap retraction on climb-out). But of course, this requires code and aircraft-dependent data (though maximum rated speed for each flap setting is usually given in pilot manuals) When we finally get an FMS, it will of course compute notches on the speed tape for flap retraction, given the gross weight of the aircraft and so on but that's *a lot* of C++ coding. - I *really*, *really* need the ADF indicator on the NAV display. Especially intersecting an ILS localizer, I keep over-shooting because the 747 turns so slowly, when normally I'd use a handy ADF to work out when I'm almost on the glideslope and hence start turning in. Anyway, that's more than enough nit-picking. I'll go back to lurking and bouncing the 747 down runways..

X-Plane's approach is interesting and novel, but far from perfect. You could think of it like a virtual, real-time wind tunnel. However, because of the computational complexity of flight, x-plane can only impliment an extremely crude and rudimentary wind tunnel. It has to fill in scads of approximations and assumptions to get everything to work. That said, it is still an interesting and useful approach for some situations and you can use it to build flight models that behave reasonably well for most type of aircraft. I don't mean to sound negative here, most of the time you only hear the hype, "blade element theory", etc. etc. so I wanted to also present the other side as well. The downside to this approach is that in order to get your design to behave like the real thing, you have to go in and tweak a lot of non obvious parameters in non-obvious ways and deal with a lot of non-obvious interactions and side effects. Building an aircraft in X-plane that hits the real world numbers exactly is a little bit like voodoo. But if you are building some brand new design in your garage and want to know how it will fly (and don't have access to a real wind tunnel or super computer cluster) X-Plane will probably make a better guess at it than anything else available to an average person. It's like anything else ... x-plane has a particular approach to the problem of modeling flight. It shines in some areas, but has it's share of problems too. But like any approach, you can usually find ways to get around the weak spots to get something useful done.

This is the way it should work. But I don't have the ARM displays in there yet. BTW when waiting for NAV intercept is it just HDG (and not HDG SEL) annunciated? IIRC selecting NAV in the autopilot currently sets the aircraft on a course 60 degrees off the radial. When it hits the radial it switches to a heading that follows the radial.

Again, I need more info. I'm not really sure what it should look like or how it should work. If you can help, I'll add the features. We might need to have "instrument" modules for each display and the MCP eventually. For example on the EICAS the Flap display is supposed to go away 10 seconds after full retraction. That would be an intrument module feature. Also an FMS module would obviously be helpful at least for calculating certain values based on inputs. To start with this could be done using the GUI interface (a dialog for each page). I'd also be able to add things like thrust level control and flare to the autopilot if I knew how they were supposed to work. > Anyway, that's more than enough nit-picking.

Re: [Flightgear-devel] 747 Panel Feedback
Are you talking about the xml files for 3d animation? The "objects" refered to in the xml are specific polys on the display. For example the apalt1 on the PDF might refer to the first digit on the AP Altitude setting display, apalt2 the second digit. For the most part they are numbered right to left, where 1 is the rightmost digit. Ah, I didn't realize you could 'address' individual polygons this way... This is the way it should work. But I don't have the ARM displays in there yet. BTW when waiting for NAV intercept is it just HDG (and not HDG SEL) annunciated? IIRC selecting NAV in the autopilot currently sets the aircraft on a course 60 degrees off the radial. When it hits the radial it switches to a heading that follows the radial. There is some voodoo I put in there a long time ago to make sure the 747 didn't overfly the radial. Any suggestions on how this mode should actually work? Also, at what point (degrees from radial?) is the radial considered "intercepted"? HDG SEL is right, I think. here's how I remember it working in the PMDG 777: assume no LNAV mode is active, or HDG SEL is; providing you have a valid NAV 1 signal, and the line projected from the current position of the airplane along the heading at some point intersects the radial, I think NAV mode will arm. Certainly it always has when I've tried. It obviously can't be a pure angle cutoff, because you might be flying very close to the radial, but almost parallel to it, and NAV should still arm. Anyway, the NAV mode stays armed until you get 'close' to the radial, at which point it activates and executes the turn to bring the aircraft onto the radial's heading. I'm not sure how 'close' is quantified, but in the PMDG 777, it never over-shot, so it must be a bit cleverer than a fixed distance. Actually the autothrottle is now outputing a trend value. I'm just not sure exactly how the graphics should look. It's a green purple line on the speed tape, with an arrow at it's top / bottom indicating the speed in K seconds (I think K = 5, but it might 8 or 10). The other end of the vertical line is fixed at center of the speed tape. Visually, you use the height of the line to judge the plane's acceleration. I googled for 'boeing PFD' on images.google.com, and some of the pics include the speed trend line. Also, some of them also show the yellow right-hand speed-tape border than indicates warning speed regimes, and the red dots that indicate danger speeds. I'll be doing an EICAS display that will have that. Also there's a center console thing, not sure when the center console will get done. Are the number of flap setting and the detents correct, btw? - I *really*, *really* need the ADF indicator on the NAV display. Especially intersecting an ILS localizer, I keep over-shooting because the 747 turns so slowly, when normally I'd use a handy ADF to work out when I'm almost on the glideslope and hence start turning in. Again, I need more info. I'm not really sure what it should look like or how it should work. If you can help, I'll add the features. Ah, the ADF is pretty easy, it's just a green arrow on the NAV display, with the the head in the 'compass ring' pointing at the NDB, and the tail (which is forked) also in the track. I can't remember if there's a solid line between the head and tail or not. Hopefully, Dave Culp or someone else who's looked at these things for too long can fill in more gaps, or correct any mistakes I've made.

[Flightgear-devel] Instrument Flight Test: Passed
I passed my instrument flight test this morning -- thank you all for the positive karma you sent my way. We did the test in the real thing, hard-core IFR with a 400 ft ceiling and rain. My visual contact with the ground during the entire test was probably less than two minutes. A narrative follows for people who like that kind of thing (everyone else can stop reading now). The ground work went fine, but I wasn't worried about it. After startup and clearance copying, we taxied to 04, and I double-checked the ceiling with ground before switching to tower (when the DFTE asked earlier, I told him that 400 ft would be my personal limit). At that point the DFTE took the foggles from me, said that I obviously wouldn't be needing them, and put them away for the rest of the flight. We took off, and in a few moments, the world vanished into white all around us. We were cleared up to 6000, then direct to the Ottawa VOR to start a simulated cross-country to North Bay. At the VOR, I turned onto V316, intercepted it promptly, and was stabilized on course and groundspeed by 2 DME (not bad, since we were 1 mile above the VOR to start with). I then hauled out my E6B, calculated a revised ETA and fuel burn based on my current DME groundspeed, and then just sat back and relaxed the rest of the way out to 9 DME. Ottawa Terminal then cleared us back to the VOR for a hold north on the 360 radial. I flew back the 270 radial (90 TO), then turned sharply to intercept my inbound radial outbound with reverse sensing for a parallel entry (I like doing it that way, so that I get DME groundspeed readouts to plan the rest of the hold). We did a couple of laps in the hold, then I asked terminal for a couple of vectored approaches (no full procedures in hard-core IFR, since I'd mess up their very busy airspace). They vectored me around for a while, then set me up to intercept the NDB 07 (at which point the examiner failed my DME, just to keep me honest on the stopwatch work). The approach went fairly well -- I did bust MDA by 20 ft, but caught it and recovered in less than a second, and the DFTE didn't mention it in the debrief. My compass precessed a few degrees during the descent, so I ended up a bit away from the runway when we got a glimpse of the ground straight down through the mist just before going missed, but there's nothing to do about that. Tower handed me back to terminal, who vectored me south to bring me around for the ILS 07 to a full stop. I asked for a bit of time to prepare, but they had a boatload of arrivals about to hit (all airliners), so I agreed to go straight to the approach and just asked not to be vectored too close into the NDB on final. They brought me around for an intercept 8 miles out and then asked for maximum approach speed, so I opened the throttle, pushed the nose down, and shot on in at 110 kias. The needles stayed nicely centred all the way, but I did feel my first unease in IMC when I thought of how fast I was flying and how close to the (invisible) ground I was as I got closer to DH. The runway came into view less than a mile back, just as I was calling out advisory visibility, and 50 feet above DH the DFTE said "OK, you're visual, go ahead and land". Fortunately, 07 is an 8000 ft runway, since I was at 110 kias and 250 ft almost over the threshold and the runway was wet and slick. I brought up the nose and dropped flaps, but I didn't want to do any serious braking on the wet surface, so I let the plane roll on past the intersection with 14/32, ending two or three miles on the far side of the airport from our destination on the North Field. We had a long taxi back, but the DFTE didn't say anything about whether I'd passed or failed, and the 20 ft MDA bust started to loom larger in my mind. When I came inside (wet) for the debrief, he chewed me out for not putting on carb heat every 15 minutes or so in IMC (not part of the test, fortunately), then filled out the examination form in front of me from memory. The NDB approach was one of the last items, and it was only when I saw him give me a 3/5 for that that I was fairly certain I'd passed. He then shook my hand, told me that I was a good, safe, competent IFR pilot, and endorsed my license. Well, that's it for now.

Congratulations! Had no doubts... For an IFR interested VFR student, what's an MDA, and what does it mean to bust it by 20 ft? I'd guess at "minimum designated altitude?"

Non-precision approaches (such as NDB, VOR, LOC, LOC-BC, and GPS) provide only horizontal course guidance. For altitude, you pass a series of step-down fixes (such as a DME distance or a radial from another navaid), where you're allowed to descend to a new altitude limit before levelling off again. The last levelling-off altitude is the MDA, and you cannot go below that until you actually see the runway. 500 ft AGL is a typical MDA, but it can vary by an enormous amount. Precision approaches (such as ILS) have a decision height (DH) instead -- that's the lowest you're allowed to go on the glidescope without seeing the runway. When you hit DH without visual contact, you go missed immediately, without any levelling off. DH is usually 200 ft AGL, lower for a specialized Cat II approach. Here's an easy way to remember: from the side, a precision approach looks like a ramp, while a non-precision approach looks like a staircase. > Maybe if I ask enough questions, I'll have you on the road to CFI/CFII...

It's actually fairly easy when you're being vectored -- ATC says "turn left to 160" and you turn left to 160; ATC says "not below 2000 feet" and you descend to 2000; etc. The hard part is when they put you on your own: "cleared to the Gatineau airport for an approach", "cleared to the full procedure NDB 07 Ottawa", and so on -- now you have to figure out your own transitions, entry patterns, altitude restrictions, and so on, all the while not forgetting to keep the dirty side of the plane facing down.

It also sounds like another big portion of the training is learning how the instruments work at a very detailed level. This gives you an understanding of the types of sensing errors you might see and under what circumstances. It also gives you a good idea of what sorts of failures you might encounter which helps you spot the failures earlier, understand what system has failed, and then know what steps you can take to either correct the situation or know which remaining instruments you can still depend on. And since you can't put your plane on pause like a sim, you have to practice practice practice so you know all this stuff at a pretty intuitive level. So should I add a claim to our home page that 100% of people using FlightGear as part of their IFR training have passed their test on the first try? Or let's see we could flip that around and say if you are smart enough to pass your IFR test on the first try, you will know enough to use FlightGear as part of your training. :-) Regards, Curt. -- Curtis Olson IVLab / HumanFIRST Program FlightGear Project Twin Citiescurt 'at' me.umn.edu curt 'at' flightgear.org Minnesota http://www.menet.umn.edu/~curt http://www.flightgear.org ___ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel

Yes, but the funny part is that you cannot use most of that knowledge, except in an emergency. Once you're being vectored, you cannot reset your HI even if you notice a disagreement between it and the mag compass, for example. On takeoff IFR, you're not even allowed to put in a wind correction, so you have to watch the airplane drift off the side of the runway (as long as you can see the ground). Enroute, you have to use the altimeter setting that the whole ATC sector is using, even if you can get a much more accurate one from a nearby airport. As Alex has tried to explain before, 90% of IFR training is The Scan. I thought I understood that when he wrote it, but I was wrong: you cannot really understand until you've done a lot of it. The scan is a hard thing to describe -- it's not just a physical process of looking at different instruments, but more like the whole Zen of IFR flying. It's sort of like driving a car while holding your speed right to the kph/mph, watching the rearview, keeping lane position within a foot, and still being able carry on a conversation, only much more so (say, with a newspaper over the windshield). > So should I add a claim to our home page that 100% of people using > FlightGear as part of their IFR training have passed their test on the > first try?

[Flightgear-devel] Gear set-up problems
Hello All, I think I've found a bit of a problem with the way that u/c gear is being defined. In the preferences file there's a single gear entry with three wheel entries to handle the brakes. While this is fine for light a/c with fixed gear, it doesn't work right with larger a/c with retractable gear. To model independent suspension we need to specify a gear entry for each gear leg so we can get the individual compression for each one. We can then specify each of the wheels on each of the legs and specify the brakes for each wheel. While I can do this in the a/c config files, the brake settings in preferences.xml seem to take precidence so I only end up with three brakes working. While this is ok on tricycles and tail draggers, it's not good for a/c such as the 747 and b52, which both have four main gear legs, with four and two brakes respectively, on each leg. The AN225 I'm working on has 14 main gear legs (each with two wheels) + two nose gear legs (again, two wheels each), so I'm seeing a few problems ahead;) It seems to me that we may need to update the a/c configs that use a single gear entry with multiple wheels to use individual gear entries for each leg and then update the supporting files, such as preferences.xml, keyboard.xml and the joystick configs to use the proper structure, allowing for up to six wheels/brakes for each leg. One benefit from getting everything set up like this is that it should make it possible to model gear failures, from entire leg failures, through tyre blow-outs, to individual brake failures. Could someone check that I have actually got this right and I've not missed something here? If I haven't made a boo-boo, what is going to be the best way to deal with it?

Actually that isn't really true. The A4 will fly all day long upside down. Some planes don't fly inverted well anyway, and I would guess the 747 is one of them. IIRC the tail incidence is different than the wing on some aircraft (like the P-51) and that causes a loss of lift when inverted. The camber would be an issue as well, I would think.

Actual IMC affects different people in different ways -- some pilots absolutely hate it (the way people hate hornets or fingernails on a chalkboard), some don't mind it in small doses, some will fly a whole trip IMC as long as they have an autopilot, and some don't see any big deal in hand-flying IMC. I'll see which category I fall into when I have more real (non-training) experience, but so far, I feel very comfortable in actual. > > When I came inside (wet) for the debrief, he chewed me out for > > not putting on carb heat every 15 minutes or so in IMC (not part > > of the > > What happens if you do or don't turn on that carb heat? When the fuel vaporizes, it has to draw heat out to do it (the same way water draws heat from your skin when it evaporates), so the carb venturi can become very cold even on a hot day -- if it is humid or your are flying in cloud, the moist air can form ice inside the carb until eventually the air supply to the engine is choked off. As a result, all carbureted engines are required to have an alternate air source that can heat the air (usually unfiltered) -- when you pull carb heat, air heated by a shroud around the exhaust flows into the carb instead of the colder outside air. Of course, if you let enough ice form that the engine stops, there is no hot exhaust, and therefore, no way to melt the ice. The 140 hp, six-cylinder Continental O300 engine used in the Cessna 172 up until 1967 was notorious for carb ice, as was the smaller Continental engine used in the Cessna 150 (I don't know about the 152). When Cessna switched a four-cylinder Lycoming engine for the 172 in the late 1960's, the carb ice problem became much less serious, since the Lycoming carb draws its air past part of the (hot) oil system. The Cherokee is even less likely to develop carb ice, since its Lycoming engine is more tightly cowled and tends to run hotter. Because of the early problems with the Continental engine, the 172 POH had all kinds of warnings about carb heat, including a requirement to turn on carb heat for landing and any procedure (such as descent) where RPM fell out of the green arc. Cessna left those in when it switched to the Lycoming until it switched to the fuel-injected IO360 in the 172R, and generations of students and teachers in 172 have had the carb-heat rule pounded into their heads. That's never been the case for the Cherokee -- the POH does not recommend carb heat for descent, landing, or other low-power maneuvers, and suggests putting it on only if carb heat is actually suspected.

Only nit is I'd like to see the nav column a little narrower (smaller type on the green links).

So the examiner's admonishment was unfounded? I take it you didn't argue with him on this point :-) I take it with the Piper there's some warning before it's too late. We hope... or will you be thinking about this email some snowy night in March with engine out and 5000ft of air below?

It's not worth breaking standards just to support an old day version. Please upgrade. There are plenty of new and free alternatives available, even for slow machines. If you can solve that problem in a way that you can keep standard conform html code then do so, but don't do it if the only solution is a mess of none standard conform html code.

This is fixed in CVS. Unfortunately, fgfs ignores lower case icao codes now, rather than accept them.
