Have You Ever Had The 737 Lift Off Before V1 Speed?

[Gregdpw 0]

I have been flying the pmdg 737 for about a month now and never had the plane start lifting off the ground on its own at 120 kts. Maybe from now on I should always put a bit of presure on the yoke. I know the manual says to put a bit of down presure to hold a stright line. But never really had to until today.

120 for V1 seems like an almost empty plane , and due to its lightness it may be very sensitive and eager to takeoff . This is only from personal experience

Check your controls for calibration or spiking... maybe its sending some erroneous pitch up input

 

Are you sure you're calculating your V speeds properly? Depending on the variant, the TOW and other factors, 120 KIAS is a perfectly valid Vr...

Yes, with improper trim settings.

V1 isn't stall speed - definitely possible for it to rotate off early if you're not pushing forward and the trim is too nose up.

Your right. Didn't set the trim. I was just messing around learning the long state start. Thanks

I believe this means up to 80 knts, to enable stable nose wheel steering. At 80 knts, the rudder then becomes efficient and the forward pressure can be backed off ?

The fcom states to maintain light forward pressure , it actually never mentions backing off it. (Until Vr of course)

80kts. FCTM.

Ah knew fcom didnt mention from memory... not read fctm for ages.

The correct sequence of events is: Vmu, V1 Vr V2

Your a/c should always be able to get off the ground before V1. And that speed is Vmu-Minimum unstick.

V1 is not the minimum take-off speed. It is the point at and beyond which you are committed to a take-off.

 

You need to check your manuels for the weight and balance schedules and note the numbers given for all four V speeds quoted above.
