Please, please do NOT turn on **all** your lights when lined up on a runway. #1, it blinds the heck out of everyone holding short right beside you at night. #2, it tends to create much anxiety for someone who is crossing the runway down field, as your aircraft all lit it gives the impression that you've gotten takeoff clearance.
Runway turnoff and wing illumination (ice lights) are fine in position. The rest (Strobes and landing lights) on when receiving takeoff clearance.
This seems to be an issue with non US airlines. Taxiing around at JFK at night, it is not uncommon to be blinded by a foreign airline taxiing straight towards you with a bunch of lights right in your face. Seems like common courtesy goes out the window. If you're facing someone, especially at night, turn off your forward facing lights!
Airbus extendable landing lights cause a loud rumble for anyone sitting in rows over the wing. I agree, switch them off when retracting flaps. Leaving them on to 10 is just plain loud. Turning them on at 10 on descent, same thing: turn them on when extending first set of flaps. Same goes for 737 belly extendable lights. Company sop should leave room for captain discretion.
Just some observations...carry on. merry Christmas to all!
