Strobe Lighting Question

Thu Jan 19, 2006 11:58 pm

Basically, I'd like to know if Boeing and Airbus have a different strobe light pattern?
e.g.I have noticed many Boeing a/c have a patern like this 1...2...1...2...1...2 etc, whereas Airbus go 1.2...1.2...1.2...1.2... etc
Its like Boeing a/c have one flash a second and Airbus have two.
Is this true, or is it my imagination? I have never seen a Boeing a/c do two flashes in a second, although I have seen A have one a second, but not very often.
I know this is a weird way of explaining, but its been playing on my mind for a while. Is it maybe something to do with the country?

Thanks

I don't think Boeing has had an airplane with a 1.2...1.2 pattern since the 727-200's (i.e. Western and some UA). Otherwise, the rest of the Boeing airplanes have the other pattern.

I just saw an airplane yesterday with strobes on the leading and trailing edge of the wing and they'd flash once each alternately.... I'm thinking it was a 737?

I think any differences have to do with a particular manufacturers feeling of what is most visable. I know airbus flash 2 or 3 times successively and I've seen some only flash once at a time and others as many as 4 or 5.

Airbus aircraft strobes flash 1.2...1.2...1.2... with the red beacon flashing in between 2...1. that is a least how it is for the A320 family, and im pretty sure for the A330, A340, and A380.

Now, Boeing aircraft, they don't really have any flash order. The older 737s (100/200/300/400/500) just flash randomly, while on the 737NG the wing strobes flash at the same time, but Boeing aircraft don't have any flash order or any synchronized with any of the other strobes or beacons.

Are you going to say that Airbus has a synchronization between the strobe and beacon lights?

BTW, I check all these lights every night and I´ve never thought one second about the "flash pattern"...
This job sucks!!! I love this job!!!

Airbus does have a synchronization between the strobe and the beacon lights. heres an example if what it looks like
1=1st wing strobe
2=2nd wing strobe
3=beacon

1.2..3..1.2..3..1.2..3..1.2..3 so on and so forth

The A320 series has 2 lamps in each wing tip that flash alternately. A single strobe does not flash twice to produce this effect.

Airbus uses a direction identification logic in their strobe lights. Forward facing strobes (left and right wingtip) double flash, whereas the rearward facing strobe is a single flashing unit. As a result you can identify whether the aircraft is coming towards you or away from you by the strobe flashes (double = towards you, single = away from you).

This system is more expensive a strobe units are not interchangable, although some operators have!

At night the Double flash on the Strobes help distinguish Airbus from Boeing on Approach at night apart from the Landing lights distribution while We await our Aircraft.
