Since i work around the full mixed fleet of AWA planes daily,let me add some observations.
our A319's & A320's do in fact have two seperate wing tip strobe lights, within the same wing-tip housing. they do blink in sequence (1st, 2nd, 1st, 2nd,etc..). the anti-collision beacons are red & blink in sequence. oddly, the rear strobe @ the aft of the fuselage is a white single blink only. the single blink is in sequence with the 1st wing-tip strobe. when Lufthansa operated FRA
, we used to watch it land & take-off. the A340-300, has the exact same wing-tip strobe pattern & anti-collision beacon pattern as the A319 & A320.
our 757-200's have a sequenced red anti-collision, followed by the sequenced white wing-tip strobes. the HA
767-300, has the exact same sequence.
's 737-700/800/900 (AWA handled CO
Ground Ops @ PHX
until summer 2003) have the same sequence as the 757 & 767, except that the single rear strobe @ the aft of the fueselage blinks randomly or out of sequence.
rather strange how aircraft strobes & beacons flash qualities differ.
