LearJet Training Resources    |   Part 135 Training Resources

1. With the loss of airplane electrical power, the anti-icing system will be lost on:
A.All systems
B.Pitot, static, and Pt2 Tt2 probes only
C.All systems except the nacelle inlet lips
D.all systems except the windshield and radome alcohol system


2. The internal windshield heat defog system uses
A.230-VAC power
B.163-VAC power
C.An electrically heated coil in the cabin heat system
D.Engine bleed air pressure


3. Anti-icing equipment must be turned on:
A.When in icing conditions
B.Before entering icing conditions
C.Before Takeoff
D.During climb out


4. The alcohol anti-ice system may be used to anti-ice the
A.Radome
B.Copilot's windshield
C.Pilot's windshield
D.Both A and C


5. Exterior windshield anti-icing, and rain removal operate on
A.DC Power from the WSHLD HT circuit breaker on the left main bus
B.AC Power from the WSHLD HT standby inverter on the right main bus
C.Power from the DEFOG circuit power barrier on the left main bus
D.Power from the constant speed drive, and from the essential bus tie breaker


6. Bleed air is not available for windshield anti-icing
A.on the ground
B.in flight when DC electrical power is applied to the airplane
C.with both the left and right emergency pressurization valves in the emergency position
D.with both the left and right emergency pressurization valves in the normal


7. Under normal conditions the windshield heat bleed-air temperature is automatically controlled. If either outlet nozzle temperature reaches the ground limit or the flight limit while airborne,
A.the thermoswitch will extinguish the green WSHLD OV HT light on the glare shield and cause the solenoid shutoff valve to close
B.the thermoswitch will illuminate the red WSHLD OV HT light on the glare shield and cause the solenoid shutoff valve to close
C.the high temperature limit is exceeded on the ground due to the failure of the squat switch
D.the high temperature limit is reached due to the failure of the pressure regulator valve


8. The windshield/radome anti-ice system
A.is still operational if both emergency pressurization valves are in emergency (provided DC power is available)
B.is operational if both emergency pressurization valves are in emergency
C.is not operational unless both emergency pressurization valves are in emergency
D.may be operational provided that the air cycle machine input pressure is equal to 35 PSI


9. During night operations, the windshield ice detection lights indicate ice or moisture formation on the windshield. Ice detection lights normally shine unseen however they will
A.reflect red spots if moisture has formed on the windshield
B.reflect red spots if ice has formed on the windshield
C.reflect red spots approx 1-1/2" in diameter if ice or moisture has formed on the windshield
D.reflect red spots when the anti-ice system is working normally


10. The ice detection light on the pilot's side
A.is inside the anti-ice airstream; the light on the co-pilot's side is located outside the anti-ice airstream. For this reason, the co-pilot's light should be monitored when flying in icing conditions.
B.is outside the anti-ice airstream; the light on the co-pilot's side is located inside the anti-ice airstream. For this reason, the pilot's light should be monitored when flying in icing conditions.
C.is outside the anti-ice airstream; the light on the co-pilot's side is located inside the anti-ice airstream. For this reason, the light should be tested with the light test switch every 5 minutes when flying in icing conditions.
D.is automatically illuminated when flying in icing conditions.
