Not wishing to hijack your thread, but in an allied vein I still cannot understand the captains who won't turn on the nosewheel landing light for takeoff or landing but are happy to have the wing-mounted landing lights on. When asked why, they can provide no reason or, for landing, resort to the fatuous "Well, the landing gear is still up so the light won't come on". Yes, I know, Mr Boeing designed it to come on when the gear is extended but it won't if the switch is off. Pathetic.
