Q

What should be the range of TRQ on takeoff?

A

The value of the actual takeoff torque should be anywhere between the static takeoff torque (calculated with the PC12 calculator) and the maximum takeoff torque (44.34 PSI).

Q

Are you allowed to consider the use of reverse thrust to compute your ASDR?

A

No, brakes only!

Q

What’s the difference between Vref and Vapp?

A

Vref = 1.3 Vs = 50ft mark speed
Vapp = Vref + kve

kve = (1/2 W/V) + Gust = +20 kts max
