Q

Retreating Blade stall causes

A

High speed, gross weight, density altitude, power

Retreating blade AOA must be increased to equal the power requirement and eventually stallswill stall, feel it as vibration and pitch up, because forward blade has more lift and phase lag causes nose to come up

Q

Electrical Failure

A

N: Stab position indicator will be inop with no ac power
APU emergency start procedure - perform
CMPTR PWR/RESET, SAS1, SAS 2, TRIM, AUTO PLT, STABILATOR AUTO CONTRL - ON

W: loss of electrical power will activate anti-ice, reducing max trq by up to 18 % and 49% with malfunctioning inlet anti-ice
