L1011 Belly Lights

Tue Apr 25, 2006 5:17 am

Hello all,

This will be my first posting in the TECH/OPS section, so please excuse my ignorance. Also, I couldnt find this topic.

Back in the day, I remember looking out the window at night during our MIA/LIM route on Eastern Airlines L1011s. I vividly remember staring at the engine covers and seeing about 4 or 5 red lights blinking (turning on and off slowly) in a row. Nowadays, I believe the gran majority of planes have a single strobing red light. Anyway, why the 4 to 5 lights? and why in a row? I also had a poster of an EA L1011 and I remember recalling the picture of the lights on the belly of the airplane. Thanks in advance!!

The L-1011 is equipped with two (2) rotating anti-collision lights on the bottom of the fuselage and two (2) rotating anti-collosion lights on top of the fuselage. On the later build aircraft the rotating lights were replaced by strobe lights.

I read in an article the reason they had two beacons on the top and two on the bottom is for redundancy. If one in each set burns out it can be MEL'd and the plane can be dispatched.

while thas true you can MEL it if there is none operative!
i think theres a note in the MEL saying you have to adopt a different procedure to show that the aircrafthas intent to move or the engines are running! i think you can use the strobe lights for this!
