727 IranAir ldg without Nose Gear. Video and Question?
 
Few days ago after flight from Moscow »»»



However one doubt...why no Spoilers/SB after the touchdown/landing roll?

Avoiding the possible CG change to a forward position, leading to a previous nose down attitude, maybe?

However...very nice crew job!:D

Never flown the 72, but it's the same for a 73..

Beautifully done !

If armed, the spoilers when extended would tend pitch the airplane over on the nose at perhaps an undesireable rate.

As a side note, I used to fly 727's for Iran Air in the 70's. That video brought back some memories.

Very professionaly done. Looked like minimal damage due to their gentle lowering of the nose at the end of the landing roll. I loved the 727. I would have retired in it if they hadn't screwed up the schedules at the end so much.
We old guys are lucky we got to fly some of these wonderful airplanes while they were here.

Johnson Bar system in B727?
 
A very well handled emergency landing, congrats to the crew. Never operated on the B727, just wondered if they have a similar 'last resort' system for getting the NLG down as in the B707? The Johnson Bar was stowed and operated from the Lower 41. If you are reading this Hoppy you may recall how it broke during a demonstration during '79. :ok:

As I recall you could go back in 1st class, pull a panel up, and see if the nose gear was down. I don't think you could lower it from there though. It has been 15 years but I am quite sure you couldn't.

I'd be pleased with that landing even with nose gear down....

Now just to sit back and wait for the ensuing Pprune discussion about how this couldn't be done in an Airbus, how ME pilots are pooly trained etc etc...oh, and could someone post the METAR ;-)

All three landing gear can be manually cranked down via three access hatches in the cockpit.




A crank is connected and after about eighteen million turns each one will lock down. Done this a few times in the sim many years ago practicing for hydraulic failure.



Of course if things are disconnected or broken that's another story.



Great job by the crew, the wonderful flying qualities and enormous pitch authority on the B727 certainly help.

I flew 707's for Iranair in 1975 and following a nightstop in Frankfurt, when we arrived at the airport we were told that the aircraft inbound the day before was being towed from the hangar as the previous evening they were unable to lower the nosewheel normally and had to use the emergency system as described in an earlier post. The reason it wouldn't extend was that it hadn't been lubricated. I'm not suggesting this was the case here. We returned to Teheran with no further problems.

It happened for real to me three times, once I cranked it down when I was playing FE and the other two times the guy playing FE cranked it down while I looked from the left seat.

Oops, I take that back, one of the times we had a real FE on board and he cranked the gear down. Really didn't have to watch him, he knew what he was doing.

The crew in the video did an excellent job.

As for the non-use of the spoilers, for some reason I seem to remember Boeing recommending not to use the spoilers if landing nose gear up or showing unsafe/not down and locked. But I have not flown a 727 since 1998, so I very well could be wrong. I need to dig out my old training manuals and look that up.

You want to stop even faster???

stepwilk 26th Oct 2011 23:56


(Of course, memory is one of the first things to go.)
It's the second thing to go...

My old 727 QRH says
AFTER TOUCHDOWN PROCEDURE.....
- For both main gear down and nose gear up, raise speedbrakes fully.

Anyway, nice job!

gulfairs 27th Oct 2011 21:31

18 million turns, I thought it was 18 million and 2!

Please no expert but I have seen many an aerodynamic breaking rollouts esp. on classic 747's. I feel they did not want to loose the drag of aerodynamic braking (not ideal in a normal landing) or rather risky in a normal landing. If they dumped the spoilers I feel the nose would have hit the ground with less control and at a higher airspeed. Lovely landing!

bubbers44-

Uh.....the only thing wrong with your 727 was the engines were in the wrong place and it had a "T"-tail.

You shudda flow the -8 and THEN you'd know what a REAL airplane is !!:cool:

stilton 28th Oct 2011 01:56

No problem with the DC 8 but if you'd had the privilege to fly the lovely B727
you'd soon understand the affection for it !

DC-ATE 28th Oct 2011 02:06

Well, I had the senority to fly anything and I chose the DC-8. Only "real" airplane we had after the DC-6s were gone !!

Also 2 pages about cranking the gear manually. Too lazy to copypasta any more, if you are interested, pm.
