use of lights
this is an example of an SOP of an airline.
Start taxiing...taxi light on, day or night
enter a rwy (active or not) taxi light off, inboard ldg and turnoff on
cleared for takeoff, during the day, c line above
cleared for takeoff, at night, c above plus outboard landing lts
after takeoff checklist, at night, outbd landing lights off
reaching cruising flight level, inbd landing and turnoff off, beacon and nav stay on all the time btw..
initiating descent...inbd landing and rwy turnoff lights on day or night
500 ft AGL outbd landing lights on...
leaving rwy, all landing and turnoff lights off, taxi lt on
facing marshaller, taxi light off..if u forget uīll see him cover his face, thatīll remind u.
emergency descents. all lights on(except taxi), including wing inspection light
RVSM problems that require 90š heading changes to leave an airway, all landing lights on, donīt know about wing inspection..I would turn it on I guess..
hope this helps.
