Module 12.15 External Light for General Reading

I had been searching the internet for suitable resources to introduce module 12.15 Lighting system. I found a youtube video, but unfortunately, it was uploaded by a person who is not from the industry. However the pictures and videos are useful resources.

The external lights are...
- Navigation Light - left wing tip - red, right wing tip - green, viewed from rear lights- white.
- Beacon Light - rotating or flashing red light - one on top of the aircraft and the other at the bottom.
- Strobe Light - while flashing lights at three locations, wing tips, and tail of the aircraft.
- Landing Light - used on landing and take-off, normally at three locations, wings and center.
- Taxi Light - for the pilots to see the taxiway
- runway turn off - useful for turning
- wing lights - illuminate the wings areas for ground safety and checking for the ice.
- logo light. - commercial value for advertisement.

External lights are used for different purposes. Some are legal requirements, others are operation while some are commercial. These are the uses..

1. Aircraft parked at the bay - the navigation lights are on, logo lights and wing light on.

2. Time limiting lights - The landing lights and taxi lights are high power. When the aircraft is inflight, the air help to cool the lights. For maintenance, switch it on for as short a time as possible.

3. Disturbing the eyes - both the strobe lights and beacons are affecting the eyes. Use the beacon light as necessary to show movements of aircraft or engine is running. Strobe lights to be used when the aircraft is moving in poor visibility.
