Are there any A320 operators out there who allow the crew optional use of the landing lights? Seems all airlines MANDATE the use of those lights at all times below 10,000... making one hell of a noise and vibration in the mid cabin when extended. Are they really necessary on a clear bright day that high up?
Disclaimer: at my airline, on the MD80 fleet, the extendable wing landing lights were always optional, and if used, they were not put out until at least slats/flaps extend at slower speed, so as to mask the vibration.
