Spotlights On Airbus?

Thu Jul 17, 2003 10:25 am

I was always wondering what these lights are on the fuselage of the A330? Are those spotlights of some sort that point at the engines? From my visits to airports whenever I see an A330 take off those lights shine bright and they seem to be brightest when viewed at an angle - this angle in particular... which leads me to that "engine illumination" theory. The lights in this photo are right under the "I" and "R" of the "AIR CANADA".

Though I'm not at all familiar with the A330, I believe those are the wing/engine illumination lights or the "ice lights". They illuminate the wing/engine nacelles so the flight crew can attempt to determine if ice is adhering to the surfaces.

So they are spotlights of sorts.. Are those present on all A-bus aircraft?

Offhand I can't think of any large aircraft in commercial service that doesn't have some means of illuminating the wings for ice inspection.

Any particular reason these lights aren't on more of the time? I woulda thought if they turn on landing lights 40 miles from the airport (or whatever) they might as well turn the sideways lights on too-- but they usually don't, right?

Sonic99: Those lights are called the "Wing and Engine Scan Lights." The forward one (the larger one) is 7LX, the left wing scan light. The further aft light (the smaller one) is 9LX, the left engine scan light. This is from the A330 AMM, Chapter 33-49-00, Fig. 001. Regards,

Most all airliners have those lights, even the small turboprops.

I don't know of a regulation about the use of landing lights, but there may be. Usually the company's manual of operation would tell you when and where to turn them on, but even so, the wing inspection lights are not considered landing lights. At night, they would even be a nuisance for other aircrafts in the vicinity upon landing.

Their only purpose is to enable the crew to look at their engines and wing leading edges at night.

Although it looks cool to turn them on when taking off or landing during daylight...  Laugh out loud

I have always thought that it was Landing Lights on on passing FL100/10.000 feet, in order to make the aircraft more visible as it descends into the more congested airspaces.

Hi guys.

Here's a good photo of a Boeing 727's Scan Light for the left wing. It's pretty BRIGHT eh!

Trust me, these lights are extremely bright at nightime. I remember flying along in a Royal Airlines 727-2 while enroute to Halifax from Toronto back December of 1996.

We were about a half hour from landing while decending through the dark sky at about 9:30 pm. I was looking out my window on the right side of the jet (just infront of the wing), when the pilots turned on their wing scaning lights. Holly Smokes!!!!  Wow! Suddenly it was so bright I could hardly see, because we were flying through a snow storm and the scan light was illuminating all the snow flakes as they screamed horizontally past my window. It was quite a show!  Big thumbs up

I didn't even know it was snowing out untill those inspection lights were turned on. Thankfully, the pilots turned them off for the final approach, thus I got to see the ground lights when we poped out of the clouds.

PS, I agree with Avioniker. I think all airliners have these scan lights to inspect for icing.

Here's another picture of the wing (or engine) inspection light on the port side of a new 737. If you enlarge the photo and look to the very left side, you'll see it.

B-52s don't take off. They scare the ground away.

My desktop wallpaper just changed, and I'd like to know a thing about 777 spotlights:

Are all of those three lights on the left of the frame wing/engine inspection lights?
