bank high during landing

[citizensun]

hi guys, does anyone know how much degrees of bank angle will cause the engine or the wing tip touch(whichever touch the groud first rather than the wheels), great appreciation~~

which aircraft?

ooooops, sorry~
737-700 and 737-800(which i think is the same answer to both)

It actually varies with pitch, and there is a crossover at +1° BA. Any lower pitch will give Nacelle contact, a higher body attitude will result in flap fairing contact (assuming flaps 40°). That said: (all for 737-800)

Flap Track Fairing makes contact at +12.2° pitch & 9.7° bank, this is also a pitch limit for a tailstrike. The bank limit increases as BA lessens to +1° to 17° bank. At that point there is a simultanious contact of the nacelle as well as the flap track fairing. Then, as pitch decreases further to -4° (bank required to get this low, at 0° bank the nosegear touches at -.8°) the bank limit becomes 11°.

for the -700 the maximum pitch values for tailstrike increase, and the limits for bank at those tailstrike values are slimmer.

If this may seem difficult to imagine, a detailed graph can be found in the FCTM Chapter 6 under Flare and Touchdown.

For the -800 (quoting from the FCTM 6.28) at a roll angle of 11 degrees both nose gear and engine nacelle will hit the runway at a pitch of -4°. Thats the minimum roll to cause an engine strike, at 17° bank and 1° pitch up both flap track fairing and engine will hit the concrete...

thank ya tttoon ,i found that in my FCTM, thank you for your guidance~:D:D:D

[citizensun]

and thank u too STBYRUD~

[STBYRUD]

I swear that tttoons post wasnt there when I posted :D Anyhow, you got your answer ;)

[citizensun]

it looks tttoon types faster than you STBYRUD:):):)
thank you all~:ok::ok:
