SAS system PA31T-II

Hi Porco,
the stability augmentation system stability through tension changes in the elevator downspring (you have to pull harder near to stall)
A sensing vane (r/h nose) provides AOA info to the computer, that applies steering signals to the Downspring servo actuator and to the stall margin indicator and stall warning horn.
Then youŽll find a SAS overide in case of malfunction...
BTW, altitude loss for stall is 750 feet...(about 4 times of what you need in a KingAir 200!!!)
A/C may sit on its tail, if no counterweight is placed in Nose !
(Powerback is another nono if 8th seat is occupied)
Generally W&B is not so easy in a cheyenne II, watch it carefully.


Engines on the -II are -28, 620 SHP.

Starter off at 52%(-I,-II,/56%-IIXL), anything below is dangerous ! (watch for ITT to stabilize or better drop before turning off the starter
As pointed out before, ALWAYS have a good battery or GPU. Better have it deepcycled more often than in the manual to ensure good condition.(applies to all turbine ops)
DonŽt drain your batt by using lights and other gizmos too long while waiting for eng start, most Engines that suffer damage get it during starting with low volts...
YouŽll find out, that moving powerlevers gently is always good on PT6ses, there is no need to rush anyway since the -II is definetely NOT underpowered.
