Q

How many NAV lights

A

Red/Green NAV lights: two lights on each wingtip-only one on each wingtip operates at a time (MX switch only).

White tail NAV light is actually on trailing edge of the wing. No lights on tail other than logo light.

Q

List lights

A

3 taxi, 3 landing

One set on each Nose, left-wing root, right wing root
Landing lights are the bigger ones

If those lights are left on, they turn off when gear is retracted
