Hi Curt, Always a bunny to try NEW things, and eventually got there ;=))
I think you should for sure say somewhere to add the option --carrier=Vinson when running fgfs, either via fgrun, or on the command line... Of course this is implied, but my first attempt was without this ;=(( And it would also be good to mention the aircraft is the --aircraft=f_14b-uas option... if not using fgrun, or 'Drone f-14b' in fgrun... Again implied, but not stated... So - 1. Backed up, and unzipped into f-14b 2. Loaded drone --aircraft=f-14b-uas 3. Deselected Nimitz, and selected Vinson 4. Exit and restart Attempt 1: ---------- But am placed on runway 10L at KSFO... with a view of my wheels... so ok, I launch, and it starts to circle KSFO at a very low altitude... Then click Go Home, and it heads and finds Vinson out to sea... but refuses to land... It looks like it is lining up, but on each approach, after it changed the flight task to 'downwind', it circles there... many circles, and circles... Pushing Go Home again, changes flight task to 'gohome' but on close approach, with flaps down, it veers to the left, and switches to 'downwind' again... After a few repeats of this, it eventually switched to 'final' and crashed into the sea on a too steep right banking maneuver... A reset put me back at KSFO... At least on reset the HUD appeared ;=)) I had not particularly noticed its absence until it suddenly appeared ;=() Tried another Launch! and when circling KSFO, again GoHome... This was much better in that it went from 'gohome', to 'downwind', to 'final', to 'flare'... But the carrier approach was WILD, with too large a left and right swings over and past the center landing line... over compensating... And at 'flare' it was BELOW the carrier deck level, and crashed into the behind of the carrier... Exit fgfs to think... Attempt 2: ---------- Then eventually thought of, and found the --carrier=Vinson option, so this 2nd attempt initialized on the Carrier... PHEW ;=)) But after Launch, circle a bit, then Go Home, crashed into the sea on 'downwind'... in a too steep bank... so reset 2nd takeoff, circle, and click gohome, and eventually, had a good landing ;=)) >From downwind -> final -> flare -> touchdown -> shutdown -> end - and HAPPINESS... Attached below is the usage and console output... Answers and comments: Yes, eventually got it 'working', but see the suggested clear addition of the --aircraft=f-14b-uas and --carrier=Vinson to the instructions somewhere... Having also played a little with auto line up and landing code logic I do understand this is a time consuming 'art', but was quite shocked by the multiple CRASHES before one good landing... Wild left and right crossing, steep banking and losing altitude into the sea, and crashing 'below' deck level need to be worked on... And these are strange, in that the final good landing was VERY smooth indeed... Your 'Reset' seems to reset more than just your scenario... I had disabled Global weather fetch, and cleared the clouds, but after your 'reset' they returned... And just to round out the state -> ... display, the 'gohome' state should be added to the output... there is nothing between - state -> circle state -> downwind Overall, quite some FUN ;=)) Interesting addition, so it could be put on display somewhere - an [ ] Auto-loop option, where an internal 'Launch!' is done, and after circling for say a few minutes, an internal 'gohome' done, and at the 'end', an internal 'reset', back to 'launch'... etc This 'Auto-loop' option could also vary the 'view' each few minutes ... camera -> cockpit -> chase -> flyby -> camera... HTH. Regards, Geoff.
