V speed input

TrailerSwift89

Please go to page 225 in the operation manual where it gives instructions on inputting V speeds. Is it just me or is it saying to rotate the knob to VCROSS, set 124, then turn it to VCROSS and set 172. Should that be VDOT? Also, are V1 and VR always the same?

Rotate the outer control knob to the V1 position and then rotate the inner knob until the TRP display shows our
V1 speed of 124. This is the speed at which we are committed to taking off.

**Rotate the outer control knob to the VCROSS position and then rotate the inner knob until the TRP display
shows our VR speed of 124; this is our rotation speed.

Rotate the outer control knob to the VCROSS position and then rotate the inner knob until the TRP display
shows our VFTO speed of 172; this is our final take-off speed and the speed at which we begin to retract the
flaps.**

We can then set our V2 speed of 131 in the IAS/MACH window on the MCP. This is our climb-out speed in the
event of an engine failure. In normal operations we will climb out at a speed of V2 + 10 knots.

I understand that V1 is V1, Vdot is Vr, V2 goes in the MCP and Vcross is Vfto.
I guess it's just a typo.

Thanks for reporting this. We'll get this fixed in the next manual update. As other users have correctly stated, each entry in the TRP is as follows:

V1: V1 speed
Vcross: Vr speed (or Vref speed)
Vdot: Vfto speed
