Strange Lights On 727

Wed Oct 26, 2005 5:46 pm

I recently saw a B727 for Buraq airways departing out of istanbul. The lights that would normnally be red for the beacon were strobe white, quite bright as well, and there were no strobes being used on the wing tips...

i know that beacon and anti collision are used synonymously, but is that the case? and which other a/c have white beacon lights on the belly like this 727 did?

I occasionally see various light twins flying around with white strobe beacons on their bellies. If anyone knows what models, feel free to specify.

I've seen UK manufactured Aircraft having White Anti collision lights on the Fuselage top & Bottom in lieu of the Red Lights by most other operators.Is there a reason.

The origanal Anti-collision lights on a 727 were red rotating beacons. they were replaced by strobes as they wore out in the '80's and 90's in the US. (1980's aircraft were delivered with strobes). If it had the original lights, it could have been replaced witha white strobe instead of the customary red.

Beech 1900Ds and later model King Airs, and Fairchild Metro 23s were/are delivered with white flashing beacons that use Halogen lamps instead of strobe flashtubes (a dispensation letter is needed from the regulatory Authority in this country in order for them to remain on the a/c, as the local Regs specify red beacons). I think it is just a matter of the white beacons being cheaper and more reliable than the Grimes motor-driven Tandem Oscillating beacons that Metro IIs and IIIs and earlier King Airs had fitted.
