Dumb question - take off trim

Yes, you’re right that there might be a misconception amongst some people. I certainly never meant to imply that the take off trim position should be an exact setting to ensure that the aircraft will lift off by itself, but it should allow you to lift off with relatively minimal inputs - such that you aren’t struggling to get the nose off the ground at the typical take-off speed of the aircraft.

Maybe the new flight models are causing the issue (much like the lack of adverse yaw we have), or maybe the neutral/initial trim positions are set wrong in the aircraft configuration. I’ll log it with Zendesk later as it certainly doesn’t feel right to me.

As long as the flight models are WIP, the takeoff trim settings will most likely change with each version.

Should be a 5sec fix to adjust to your liking in the flight_model.cfg, aerodynamics section.

Except e.g. the Mu-2 :wink:

Maybe, but while things are still quite fluid with updates and changes, I am trying to avoid making too many tweaks of my own for now (even using the Community folder to do so) so I don’t begin introducing my own problems. I’d also rather get flying than spend my limited time tinkering and reloading the game to test changes. I am determined to avoid turning MSFS into another FSX with a million tweaks, file changes and other adjustments :grin:

Nothing in particular jumps out at me in flight_model.cfg regarding neutral trim positions, so using the analogy of taking a sledgehammer to crack a nut, the ‘best’ solution might be to tweak this:

htail_incidence = 1 ; Horizontal tail incidence (DEGREES)

I know that some of the parameters in the aircraft files are only relevant for the legacy flight model, and I suppose that will become clearer with time.

This value might help correct the indicator in the cockpit so it behaves more accurately when in the take-off position, but nothing more:

elevator_trim_neutral = 1 ; Elevator trim max angle (absolute value) (DEGREES), for indicators only (no influence on flight model)

For now I’m willing to wait as it’s easy enough to work around by adding a dollop of nose up trim before or shortly after take off.

Take off trim?

Well let’s see.

It’s about the same as landing trim.

You don’t need to even use it.

Just throttle to full, and take off.

Throttle at zero, and land.

You literally don’t need to use the flaps on the GA aircraft at all.

According to this sim.

You also don’t need reverse thrust on the GA aircraft that have it, apparently.

Don’t understand what you are trying to say (or what ‘landing trim’ is).

Everything you wrote applies IRL as well.

Oh wait… I was thinking Flaps.

Too annoyed to pay attention this morning.

Of course if Flaps don’t matter, trim certainly doesn’t.

Trim is completely unusable for me in this sim anyways. And still doesn’t work after multiple patches.

Once I’ve got used to the small initial delay, trim works for me ok on all aircraft.

No problems with no-flaps landing either. Still don’t get it what you are complaining about, except trim.

FYI, even on airliners reverse thrust isn’t considered on dry runways.

Have a good time then!

Thank you :slight_smile:
