Flashing Red Lights On Bottom Of Aircraft

Mon Sep 12, 2005 9:58 pm

(A question similar to this one: Rotating Red Lights On Fuselage & Blinking Ones (by Vimanav Aug 26 2003 in Tech Ops))

Are those lights called strobes? Or are strobes just the lights on the wing tips? Also do the red lights on the bottom rotate (like a fire engine's lights) when on the ground, then flash when up in the air? I seem to have noticed that.

That's right. The two flashing red lights on the top and bottom of the fuselage are the beacon lights and the white one's on on each wing tip are the strobe lights.

As far as I know it seems to be the older aircraft have rotating beacon light/s? Correct me if I'm wrong on that one.

The strobes are the white flashing ones in the wingtips.
The Navigation lights are the red & green in the wingtips.
The beacon is that red one that you say, and is indeed used to tell that the engines are running.

No, it rotates also in the air, but you don't notice it because you wont see that ''going around'' thing that reflexes on the ground, instead, if you are looking sideways and it's spinning, you'll see it go on and off cause you see the back part when its spinning and its pointing to the other side, thus making it look like flashing from the distance. I tried to be as clear as I could.  Smile

Pay heed to those anti-collision (beacon) lights. I've seen a few baggage carts get toppled after a careless ramper drove behind a running engine or two.

Strobes are a type of lighting system. You can have strobe beacons, rotating incandescent beacons, flashing incandescent beacons, and LED beacons. Similarly, you can have wingtip strobes, wingtip oscillating incandescent lights, wingtip flashing incandescent lights, and wingtip LED lights.

The bottom line: Not all beacons rotate and not all wingtip lights are strobes.

Here's a strobe tube:

At my company you know when the a/c is about to taxi because they put the fixed floods on, when towing the a/c the anti-coll is switched on, this is also switched on prior to start, never heard of it refering to engines being running, the red and green lights at the a/c port/starboard side are nav lights or ordnance lights (including the white light at aft of a/c (reversing light)) the white flashing ones are strobes and red flashing/rotating are anti collision lights.

Gotcha'

And a quick refresher- green on the left wing, red on the right? And old flight sim manual said it was so that other aircraft could tell which direction the aircraft was flying in.

Red on Left, Green on right. If you see a green light, he's flying from your left to your right. If its red hes flying from your right to left. If its white he's flying away from you, and if it's Green on your left and red on your right, then watch out 'cause he's coming straight at you!

Mnemonic: "There's no red port left".

The rotating beacons on is the indication rampers are looking at to see if the engines are running. Pilots messing this up better be careful during their walk-around... I once got a dose of hot air down my neck when putting the blocks on an aircraft where they had turned off the beacons prematurely, and I was not a happy camper.
I thought I was doing good trying to avoid those airport hotels... and look at me now.

At my flight school, the strobes are referred to as anti-collision lights (as part of a mnemonic for what is required for night flight). The Warriors that are used don't have beacon lights at all - the strobes are used during the day, and the navigation lights are used at night.

I've always used the terms beacon and strobes to avoid confusion.
