Hey guys
The L1011 is a great plane.But I think that the elevator trim response is way to small during landing.Any ideas how to improve this?I already modified the elevator trim effectiveness scalar in the aircraft config but this does not seem to do much.Any help is appreciated!

Yes I found the same problem, the only way to overcome this, is to limit flap setting to <22 degrees, once flap setting is greater that this it becomes almost impossible to control elevator. I posted this problem but had no response too.

Only just seen this and must have missed the original thread - sorry.
It's been a while but from memory, the Tristar has what is called 'Direct Lift Control'. I think the requirement for this is that the aircraft is set up for landing (gear down, at a sensible attitude) and then when the last 2 (?) stages of flap are used the elevator control is minimised (I hesitate to say disconnected ) and the fore / aft movement of the yoke controls the spoilers. The effect is that you control altitude with stick, pitch having been set previously and maintained by the onboard systems. It would be worth a quick search on the net for Tristar DLC as the information is out there. It does feel unnatural to begin with but once you are used to it it works quite well. Cheers, Paul. |
