Re: [Flightgear-devel] C172p 3D Turn-Coordinator
Hi Stuart and Heiko, I seldom saw such a fantastic responsiveness in my life - thanks a million. Sorry that it took me so long to say thanks a million - I had a hard time learning how to get the new Beauty out of the GIT - so I even had the chance to learn something new. I like that TC very much - looks great and is much better to read. Seconded - thanks for the effort! It still shows the Standard Rate of Turn at 15° (instead of 20°) - but for sure that is not an issue for me (may just be a reminder for a beauty-operation for that Beauty-Queen with the next service!) The T/C should show standard rate at a standard rate turn, which is 2minutes for a 360 (3deg per second). The corresponding bank angle depends on the airspeed of the aircraft.

Re: [Flightgear-devel] FlightGear Newsletter J une 2010
Hi devs! Another month's (almost) over, another newsletter is written. A big thank you to all contributors! This month's edition is quite special, as it is the 12th edition! I will try to come up with something special for next month's jubilee edition ;) Have a look at it: http://wiki.flightgear.org/index.php/FlightGear_Newsletter_June_2010 Contributions to next month's newsletter are welcome at this link. Everyone (with a wiki account, which is free and easy to obtain) is welcome to add a paragraph or more about updates that (s)he noticed, created or used. Have a look in the archive for ideas on what could be written about. Cheers, Gijs PS: Any faults/mistakes that are to be found in the newsletter should be send to me, as the article is blocked for normal user edits. _ Al je email accounts in 1 inbox.

Once Heiko had mentioned that we had higher resolution textures available, it was trivial to update. It still shows the Standard Rate of Turn at 15° (instead of 20°) - but for sure that is not an issue for me (may just be a reminder for a beauty-operation for that Beauty-Queen with the next service!) Apologies - I thought that was a reference to the (now retired) turn indicator rather than the turn coordinator. Just to be clear, are you referring to an inconsistency between the markings on the instrument, and the actual angle of bank required on the c172p to achieve a standard rate turn? Following on from this, do you know which is correct? -Stuart -- This SF.net email is sponsored by Sprint What will you do first with EVO, the first 4G phone?

[Flightgear-devel] C172p 3D Turn-Coordinator
I tried to find some more sources to trust on the correlation between Banking and Turn-rate. But the only one I found stating a direct relationship, and backing that up with a nice formula is our FlightGear Manual (FlightGear-2/data/Docs/getstart.pdf, page 101, ch. 7.4 Basic Turns) which I try to translate right now (that's where those nitty gritties come from) - and even there it is stated that that is true for a c172p. Other sources like C172 real Manuals, FAA, Student Pilots Flight Manual (1970), Manufacturer of TC, etc. just seem to see the Banking and Turn-rate as independent things. So I tested it once more on my FGFS 1.9 Ubuntu 10.04 - this time not trusting my Pilot Skills but taking: simulator fair weather, artificial coordination of Rudder/Aileron, constant height 2500ft at 120 kn over KOAK, doing 2 circles for trimming and then measuring 3 without changes: - the old c172p 3D with TI: 5:48 Min at Banking ~15° (1 min 56 sec) - the new c172p 3D with TC: 6:28 Min at Banking ~20° (2 min 9 sec) Yes: I take that 15° back for the new version - with the no human intervention during turns that 2 min at 20° seems to be very much ok - sorry for my doubts. And thank you - that was an interesting discussion joe -- This SF.net email is sponsored by Sprint What will you do first with EVO, the first 4G phone?
