BA's 747-400 Without Taxi Lights.

Wed Aug 09, 2006 4:19 am

Hey, im wondering why BA doesnt have taxi lights on their 747-400"s they only use the RWY turnoff lights. Even their newer 744's dont feature this.

I also noticed that QF dont have them either exept on the 744 with GE engines including the ER's. And the new 744's VH-OJS and OJU

CX dont have any either. Exept on the Ex. SQ planes.

So are these airlines planning to install them or not ???

As you can see the VS plane has lights over the runway turnoff lights.

So 2 different types of lights on the gear.

I never noticed it until you brought it to my attention. Thanks Qantas744ER. Now I know something new about 744's. Maybe a BA pilot can shed info on this.

Sorry you're wrong:





It's just a matter of whether the pilot uses them or not.

Which could be a question of whether it's dark outside or not. If it's daylight, there's no real need for the taxi lights to be on.

I dont think he is. If you look closely at the two pictures he provided, you can see that the BA aircraft has only 2 lights on its main landing gear, while on the VS B744 it has 4 lights on its main landing gear. Take a look.

This could be an option carriers choose. For example a lot of carriers opt not to have the tail lights installed.

Maybe somebody can clarify.

No problem  Silly

I also found out that the earlier 747-400's didnt have the taxi lights and only RWY turnoff lights aswell. But after Line Number 900 or something like that the airlines had an option to get them. And i think because BA does have a lot of pre LN 900 they decided not to get any Taxi lights on their newer 744's even if it was an option. So its probably just to keep the costs for spare bulbs away etc.

But many airlines like UA did decide to retrofitt their 744's. And give even the older ones taxi lights.

So for now

BA
CX
QF
LH
JL
and Korean ( cant remember the code)
Dont have them.

I don't think this is it given the first 744s off the line for NWA had the taxi and landing nose-wheel lights. See below:

I think every B747-400 has taxi lights. Thats why they are at a angle. They can be pointed forward or turn to help the pilots see where they are going. The two lights on top are just extra "landing lights" to make the aircraft more visible when the landing gear is down as compared to having just the wing lights on.
What is it? It's A 747-400, but that's not important right now.

Wrong the lights on the bottom are called Runway turnoff lights, the ones on the top are taxi lights and the 2 pairs on the wings are Landing lights.

Just look at the picture and stop playin smart  Wink

And in no way can they be pointed foward.

The tail/Logo lights are required and all 747 have them installed, however you can opt for three lights on each side instead of the usual 2. QF has three on each side and even upgraded the three A/C that were purchased second hand I believe.

Those lights don't move. I think with the lightings is adequate enough. They are pretty bright when taxi in to the gate on shining in to your eyes.

My question os why do they flash before going off when the gear is retracted.
The only valid opinions are those based in facts

Flashing before moving off I believe is to tell the ground crew that they acknowledge that they see them with the gear pins I think. You don't see them flashing in the day.

As for the second one the taxi lights and runway turnoff lights turn off automatically when the main undercarriage leaves the ground on takeoff. These lights would not come on when the aircraft is inflight even when they are turned on in the cockpit. That is why many times if you notice when the pilots have those switches on when the aircraft touches down on the main undercarriage the lights come on automatically.

Its also the same on the B757. Most of BA B757 have no nose taxi light. One aircraft, PEL I think, has a nose taxi light down between the nosewheels like most B737 have, but its the only one.
