Hello,who can tell me, why the rear light of the PJF Foker F28 flashes irregularly?Thanks for your answer, Jack

I'm not familiar with the F-28, but could it be a strobe light?John M

John,yes, this taillight is a strobe light. When the aircraft is ready for take off, the taillight flashes regularly, as the strobe at the wings. After the start, the taillight flashes irregularly. That is the problem.Greet from Switzerland Jack

It's very common to have strobes flash in an irregular rhythm, and then go back to a steady interval. Part of the secret of success in life is to eat what you like -M.Twain
