Strobe, landing and wig wags questions

[RFguy]

the sealed beams, like the classic GE4509  are pretty bright (landing lights). they are a narrow beam, draw alot of current, and get hot, and have a MTBF of perhaps 15 hours in an aircraft

something like 110,000 Cd.

My Whelen Parmethius G3 PN# 01-0772102-10   says  100,000 Cd for the first 5 minutes, then as it warms up, 80,000, and at 1 hour and max ambient is at 60,000 Cd

has 10deg beam spread.

 Rally cars used them and you can see individual insects on blades of grass, sliding  during turns. They will overheat fast in a no air over them condition like taxiing downwind.   IF you go past Tullamarine most days you'll see the aircraft landing lights of many aircraft landing on 26 or 34.  20 +kms away.  Williamtown Had approach strobe lights to the western end of the runway that were Very effective.

This fairly recent video by a young YLED (Lethbridge) pilot tells two stories from which, he says, he took lessons about traffic conflicts near airports. The first shows how the other plane's OzRwys traffic helped with separation when his own radio comms were, he thought, somewhat lacking. And the second (04:00), shows how it was the other plane's landing lights that saved the day when that pilot's radio call had placed him somewhere else entirely.  I guess we all agree, see-and-avoid needs all the help it can get.

 

Anyway, kudos to FlightFix for sharing what he's learned in such engaging, well produced videos.

IF you have vertical separation you can be sure you won't collide.. Nev

Agreed,  and in the second video story I thought he did well to descend underneath the converging Cessna because even though he too was in a high wing he probably had a better chance of keeping sight of the threat looking forward and upwards until it passed over (as opposed to climbing and losing it under the nose.)

In the first story he says they were both vertically constrained by a cloud layer just above circuit overfly height.  In that case, he reckoned his take-away was he should have been less fixated on his original joining plan when faced with unexpected same level traffic.

Good radio procedures are still a major part of this always present problem, but it didn't stop a Garuda B 707 crossing the runway as I was on late final  say 200 ft in an A 300. The quickly initiated go around by me . (I was 1/2 expecting it) resulted in missing him by about 50 ft. Potential death figure around  800.. That's at our biggest Secondary Airport. You can NEVER relax. . Be ready for anything.  Nev
