What angles do the nav lights disperse light in?
Wings 110, Tail 70 (140 total)
Why should you not handle bulbs with bare hands?

What are the 3 types of anti collision lights?
Rotary reflector, Rotating Bulb, Red Strobe type.
What generates the high intensity flash of a Red strobe beacon?
Strobe unit located independently of the strobe light, providing high voltage to the strobe at required flash rate.
What is important about the positioning of the white collision avoidance strobe lights?
Flash should be visible from any point around the aircraft in an area 30 degrees above and below the aircraft horizon.
White collision strobe lights due to their intensity are switched on when?
Just before takeoff and switched off after exiting the runway on landing.
Where are the power packs for strobes located?
In a water resistant area of the wing/aircraft
What is important about handling strobe light circuits?
Power must be disconnected for a period of time before touching. generally 5 minutes.
What are some precautions in regards to strobe lights?
1: Don’t look directly at operating strobe.
2: Don’t operate during refueling
3: Do not touch tube assembly.
Landing lights generate a lot of heat and cooled by ram air in flight, what precautions must be taken on the ground?
Do not test for extended periods of time.
If a quartz halogen bulb is handled how must it be cleaned?
Lead free spirit.
Why are quartz halogen bulbs used in aircraft taxi lights, landing lights and flood lights?
Envelopes made of quartz withstand much higher temperatures than glass, hotter filament also produces more light.
Where are the taxi lights positioned on the aircraft?
To the steering part of the nose landing gear.
What precautions are there when operating lights?
Do not operate for more than 5 minutes, allow time off equal to time on.
Which lighting is used for wing leading edge/ ice detection?
Sealed beam lamp
Cabin lights are used to illuminate the main cabin of the aircraft, where is the control for this system and where does it draw power from?
Flight attendant station, Ground service bus.
Cabin window lighting is run independently of other cabin lighting in most aircraft, how are these operated?
Fluorescent tubes are commonly used and most aircraft use a ballast unit instead of a fluro starter.
What automatic control does the aircraft have over the advisory sign operation?
1: Landing gear down
2: Flap selection is made
3: Cabin decompression
What are the 5 types of cockpit lighting?
1 Integral lighting
2 Post lights
3 Trans-illuminated panels
4 Floodlights
5 Utility or wander lights
