Pro experty něco z pprune.org:
Regarding the speed of the video... I think the majority here are wrong.
The anti-collision lights on the CRJ (upper and lower fuselage) are Goodrich 2LA 002 760-70 with 8ES 002 769-03 power supply. This has a flash rate of 45 fpm (alternating top bottom, so each lamp is effectively 22.5 fpm).
The first flash I clearly see on the top occurs at 0.05 secs, the second top flash at 0.08, or roughly 20 fpm... given the inaccuracy of the timing (lack of precision), that puts it very close to the stated 22.5 fpm for each beacon.
I think you will find this is real time. |
