Exterior lights
This is the info I got from some instructors with regards to lights usage on light aircraft (which should also apply to large aircraft to some extent, day or night)
1. Anticollision / Beacon - ON when engines are running
2. Nav/Position - ON when aircraft is manned
3. Strobe - ON when entering runway, off upon vacating runway
4. Taxi - ON when taxiing
5. Landing / Takeoff - ON when entering runway, on final approach. OFF upon vacating runway
Pls correct me if I am wrong in any of the above. Also, would greatly appreciate if someone can lead me to official documentation on the usage of these lights.
