LR ICE and RAIN PROTECTION CAS

Question 1

STAB OVHT (RED)

Answer 1

Stab overheat condition; does not automatically shutdown

Elevator buffet or stick pumping indicates ice may have formed on the stabilizer.

Question 2

WING OVHT (RED)

Answer 2

Wing overheat condition; does not automatically shutdown

Elevator buffet or stick pumping indicates ice may have formed on the stabilizer.

Question 3

WING/STAB OVHT LEAK (RED)

Answer 3

Leak detected (> 255F) in wing or stab supply ducts

Elevator buffet or stick pumping indicates ice may have formed on the stabilizer.

Question 4

L AOA HT FAIL
R AOA HT FAIL
L R AOA HT FAIL
(YELLOW)

Answer 4

Respective AOA vane heater failed w/probe heat ON; stall warning may be unreliable

Respective stall warning stick shaker and Low Speed Awareness (LSA) cue may be unreliebale in icing conditions.

Question 5

ICE DET FAIL (YELLOW)

Answer 5

Ice detect system failed

Question 6

ICE DETECHED (YELLOW)

Answer 6

Ice detected and any of the bleed air anti-ice systems is not selected ON (suppressed on the ground)

Question 7

L NAC HT
R NAC HT
L R NAC HT
(YELLOW)

Answer 7

Respective NAC S/I ON, but low bleed air pressure, or Pt2Tt2 probe heat failed

Question 8

L NAC HT FAIL ON
R NAC HT FAIL ON
L R NAC HT FAIL ON
(YELLOW)

Answer 8

Respective NAC S/I not commanded ON, but bleed air pressure is present

Question 9

L PITOT HT
R PITOT HT
L R PITOT HT
(YELLOW)

Answer 9

Respective probe heat OFF or pitot heat failed

Question 10

SAT HT FAIL (YELLOW)

Answer 10

SAT/TAT probe heat failed w/R PROBE S/I ON

The SAT probe heat is inhibited on the ground.

Question 11

STAB TEMP LOW (YELLOW)

Answer 11

Anti-Ice ON, stabilizer heat too low for effective anti-icing (> 10 seconds)

Low speed flight should be approached with care so that detection of abnormal flying qualities can be obtained. Elevator buffet or stick pumping indicates ice may have formed on the stabilizer.

Question 12

STBY PITOT HT (YELLOW)

Answer 12

Standby R PROBE S/I OFF or heater failed

The standby pitot-static mast may be visible from the co-pilot’s seat. Visually check mast for ice or damage.

Question 13

WING TEMP LOW (YELLOW)

Answer 13

Anti-Ice ON, wing heat too low for effective anti-icing (> 10 seconds)

Question 14

L WSHLD HT FAIL
R WSHLD HT FAIL
L R WSHLD HT FAIL
(YELLOW)

Answer 14

Respective system or engine alternator failed/under-temp (< 50F)

• Descent into conditions with a small split between the temperature and dew point may result in interior windshiled condensation (fogging).
• If either WSHLD switch is OFF or inoperative, circling approaches are not recommended in icing or fogging conditions.

Question 15

L WSHLD OVHT
R WSHLD OVHT
L R WSHLD OVHT
(YELLOW)

Answer 15

Respective windshield overheated (> 160F)

Question 16

ICE DETECTED (WHITE)

Answer 16

Ice detected with Anti-Ice systems selected ON, (suppressed on the ground)

Question 17

STAB TMP FAULT (WHITE)

Answer 17

One of two stabilizer sensors failed; still functions normally

Question 18

WG/STAB HT OK (WHITE)

Answer 18

Ground test of wing/stab heat system OK (checks controller and sensors)

Question 19

WING TMP FAULT (WHITE)

Answer 19

One or more of four wing sensors failed; still functions normally

Question 20

L R WSHLD HT FAULT (WHITE)

Answer 20

Respective windshield heat ON, but degraded operation (still effective)
