Question About The 727 Lights.

Sun Mar 11, 2007 10:00 am

What I remember about the 727 was that the starboard and port lights (Red,Green) would oscillate back and forth. Was this the only aircraft with this feature? If not what other airframes used this and what was the reason for them to move?

I think Eastern was one of the airlines that had this option, and I say that based on the fact that their 727s also had an oscillating light (white) in the aft tailcone fairing on top of the vertical stabilizer. Strobes were not as prevalent then, and the oscillating light was intended to catch your eye, so you'd notice the aircraft.

I know Delta also had the 727 with the oscillating wing tip lights.. NW has the 727's with the rotating anti collision light but with wing strobes until the republic merger they got the advanced 727's with both anti collision and wing were strobes. Ironic that the strobes lights you see today on most commercial and military aircraft was developed by Harold "Bill" Atkins who was a B17 and B29 instructor in WW 2 and a pilot for Northwest Airlines.

Kinda like the "Disco lights" show that your company does with the landing lights  Wink Took me by suprise the last time the tower told me to hold short for a landing 737...  Smile

Yeah, of course, those are simplier, i.e. no moving parts to break (like the old oscillating ones), just existing lights that pulse.

I used to cater at IAH in the mid-1970s, and I distinctly remember Eastern's...

Here's one:

Not all had them...but some did....

Oh, it was mechanical, not electronic. Didn't realize that...(RE: the 727's).

I've always liked the electronic pulsation of the anticollision beacon (red) that the Air Force used on the F-15's and, IIRC, the Navy also uses on the F-18...gives the bird this kind of eerie but serious appearance at night  cool

Two of our old -200s were like that, N24SW and N26SW, then Boeing started using strobes in everything coming off the line.

IIRC, the L1011s had the old-style pulse type, whilst the DC-10s had strobes....

Indeed; the L-1011s (non -500s, that is) actually have dual rotating beacons, both on top and bottom, for a total of 4. The -500s have dual lights too, but they are strobes. Anyone know why Lockheed went "dual" with the anticollision lights on the L-1011?

Dispatch reliability within the scope of the MEL. According to the MMEL, one upper and one lower Anti-Collision light must be operating. All 4 may be inoperative as long as the aircraft isn't flown at night. This allows the operator to MEL 1 upper and 1 lower Anti-Collision light and still dispatch the aircraft for night flight.

I think some of the NWA DC-9s still have this oscillating disco style light, I remember that once, when I used to fuel A/C on the ramp in MEM, one was left on, giving the ramp an interesting, red, green, and white, oscillating glow. I prefer the strobes.

Aren't strobes required by the FAA for commercial aircraft now?

All of NW's 9s have the rotating beacons. None of them have strobes. It's nice to watch them at night whenever I'm at MSP. And frankly, they're cool to watch because they spin only 180 degrees before reversing direction and going back 180 degrees, in a cycle. The beacons each have two lights on them, thus completing the 360-degree light coverage required of such anticollision lights. Just a lot more interesting than strobes which seem to lack character.

I was talking about the nav lights, and the trailing wing lights on some of the DC-9s.

If you see the wing strobes or oscillating wing lights operating on the ground on a DC-9 it is one of two things. MX has pulled the gound shift circuit breakers so he can check to see if those lights are functioning properly ot the aircraft has a ground shift problem. The DC-9 wing strobes and oscillating lights are designed to turn off once the nose gear is down after landing.

I dunno what the deal was, but I saw em' on while the A/C was at the gate, if I remember correctly, they stayed while the pax boarded, and then even stayed on while the plane pushed back and taxied away!

DHL's DC-9s (when they still flew into BIL) had the rotating beacons. Neat thing to watch. Big grin
