If someone could please explain with references the way to be sure of the Trailing Edge flaps POSITION when extending the flaps during an approach/landing on STBY power only.
The TE flaps indicator is inop and no assymetry protection is provided.
The maneuvering speed (1/5/15....) are shown on the speed tape but these are based on the LEVER position only.
The amber band for the MINIMUM maneuvering speed is getting info from the TE flaps position and from other factors(AOA,LE devices assymetry,,,,) but how can one be sure that the TE flaps are in the correct POSITION apart from checking pitch vs thrust (in the unreliable airspeed section) for example.
Thank you
