T/O 6000 19-20k 
ENRT 10500 up to 19k
ENRT 6000 19-20k
LDG 10500 up to 19k

Question 3

Answer 3

Vmini 55 knots

Vne 125 knots

Question 4

IFR Manuevering limits

Answer 4

Max 30° bank
10° right yaw prohibited
Rate of decent 1000 FPM

Question 5

IFR Temp Limits

Answer 5

5°c in IMC prohibited with inlet screens

Question 6

IFR Flight Control Systems Limits

Answer 6

SAS must be operational
Mag brake must be engaged
Speed trim must be operational

Question 7

IFR electrical failures

Answer 7

Main batt fail: TR’s provide power

Single gen fail: standby gen powers

Dual gen fail: L/R main batt and inverter

Total fail: AUX batt provides power to ECS, gen reset, STBY attitude indicator

Question 8

What fails when total electrical failure occurs?

Answer 8

All aircraft systems
Including SAS

AUX batt provides STBY attitude 
Center Ball
Reduce Airspeed
Yell instrument calls (ICS inop) 
Obtain VFR

Question 9

IFR equipment blower fan failure

Answer 9

Temp exceeds 130°f
Shut down non essential radios
Check reset fan breaker
Remove AVI closet door

Question 10

IFR SAS failure

Answer 10

Single/Dual
Slow to 80 knots or Vne
Limit bank to 5°

Question 11

IFR Performance Data

Answer 11

No Change

Question 12

How long can the AUX batt provide power to the STBY attitude indicator after total electrical failure?

Answer 12

90 mins

After power loss STBY AI provides reference for 9 mins as gyro slows

Question 13

Speed Trim Failure

Answer 13

Must operational in IMC

Flight may continue to obtain VMC
