777 Physics

    Whats your descent rate . I'm presuming your on the ILS.


    Just wondering if it's the eye position in the cockpit that's giving a weird impression and forcing you to flare more than you need

    I always stay between the center and the mark above with the ILS. Plus, my cockpit view is slightly lower than normal because of my modified 777 file, so I look more straight ahead. It's definitely not the case of eye position.

    It's not like I flare more than 5 degrees. What i mean is that I sometimes have to force more input to get to that 5 degrees with the 777 than i would in the other aircraft like the 747. It's just how the plane's physics is in the game.

    If you modified the 777 then this explains why it may fly differently. Did the last Steam update correctly change the b777.tmd file and overwrite all of your changes as is should or was the file blocked by your manual changes perhaps?

    No i didn't modify any fuel and weight stuff. I know where those are located. (Im on mobile btw)

    I created another folder for each aircraft I choose to modify so that the dlc aircraft folder is untouched and i still get updates. All I did was take the view parameters and changed the values in parameters.tmd located in my mod folder

    Though, after looking at the original post I realized i read it incorrectly. The 777 is fine and has remained the same since I started using it. I just never 100% gotten used to it 😆

    It doesn’t help to mix discussion on the behaviours of PC FS4 and Mobile Aerofly in the same thread. My unmodified FS4 777 is perfectly fine but in mobile however it does have an exaggerated ultra big plane feel with manual flying.

    The inertia in this mobile plane model is above average, a bigger heave is necessary to move it and care needs to be taken to stop it going past the adjustment desired. I find it hard to judge, the mobile 777 often is not quite in the attitude I wanted so the plane naturally wanders off.

    I think Autotrim makes it a bit worse, it ruins the designer’s hard won excellent aerodynamic stability by interfering with the speed and pitch interaction. A nose down disturbance and speed increase should pitch the plane up to restore the original condition but the autotrim (destructively) lightens the load if ‘back pressure’ (it is a tablet being hand held!) is temporarily held so the trim is made to be all wrong when speed and height are re-acquired.

    An approach is best held stable on the glide path for a good ten miles to avoid excessive auto trimming and if full flaps and 150 knots (Vref plus 5) are the final target, in mobile I need to noticeably haul it up to about plus 5 degrees on the attitude indicator as the power is pulled off passing 30-20 feet above the runway. Running an auto-land with the flight director bars and the flight path vector symbol turned off gives a clear view of the sim’s flare input, perhaps a half or a full degree less would result in a nice arrival without a prolonged float.

    This is exactly what I mean. I feel like I have to yank the nose up while landing on mobile. It's almost like the plane feels really heavy and you have to flare considerably more to slow the descent rate.

    I don't know if it's just me, but when landing the 777, I have to flare significantly to land smoothly. Does anyone else have this same problem?

    Many players have asked this question a long time ago. At present, the game basically flies at the maximum load. I wish I could customize the load, because I also find the 777 difficult to control.
