Takeoff speed bugs

The TAKEOFF page displays V1, VR, V2, VFS and calculated takeoff pitch. The values come from the performance calculation for the loaded aircraft and departure.

Check the load

Confirm the correct variant, fuel, payload and takeoff CG in the EFB and MCDU.

Check the runway data

Review the runway, weather and takeoff configuration used for the calculation.

Enter and verify

On TAKEOFF, enter the applicable values. Compare the MCDU with the source and make sure the expected bugs appear on the speed tape.

V-speed bugs

V1 is the takeoff decision speed; VR is the rotation speed; V2 is the takeoff safety speed. FSS identifies VFS as the takeoff final segment speed.

Changed inputs

Recalculate takeoff speeds after a runway, load or configuration change.

Brief the roll

On the ground, FSS describes cyan dashes when no valid V-speed data is available. Check the takeoff data before relying on the speed bugs. FSS PFD speeds ^[128]. ^[24]
