Why does the B777 have three rear facing (white) nav lights? The early B777's of United and BA only have two (each wing), and later Boeing added one to the tail as well as the wing tip ones. It can't be a wing span issue because the 744 has only one, no rear facing ones on the wing tips. The early 777's had the anti-collision strobe by the apu outlet but not the nav light. Just curious...

This is my fist post on A.net....
When the first 777s without the rear nav light were delivered to United, there were numerous instances where smaller aircraft like 737s almost taxied into the 777s at night because they were so much lower. It was hard for the pilots of the smaller aircraft to judge where the tail of the 777 ended because it was dark and so much higher. United let Boeing know about the problem after about a year of the 777 being in service with them and they added the third nav light. Now its a lot easier for the pilots of following aircraft to judge distances and prevent collisions.

Not all have the strobe on the wingtip/tail; including the DC-8,BAE-146,Fokker-F-100 to name a few."
First of all *ahem* it's M11...not DC-10 =P.
I still think all aircraft need to have a rear white nav light, including the ones you listed above:

If I am not mistaken A319/20/21 have the rear navigation lights too, but not on the wingtips
Yes the 777 is recognizable while flying at night. I live three miles north of MCO and I saw a 772 taking off to the south which had to been 5-6 miles away, but it was easilly recognizable because of the three white lights. It was most likely the BA flight since we pretty much only get one daily Delta 772 nowadays here and that departs around 2-3pm
