NP229 was one of a batch of Proctor IVs that went to the French Air Force for use by ERN (Ecole des RadioNavigants) 703 at Pau.

What was the perspex dome used for?

What was the perspex dome used for?
I don't know but I'd take a guess that it was for taking star shots for training navigators. Something like that.

What was the perspex dome used for?
Since it had a D/F loop in it, and since the aircraft was used by the French School of Radio Navigation, it might just have been used for D/Fing NDBs.

Yes, you can see the DF loop. I don't know when NDBs were introduced (non-directional beacons) but the loop in that dome would have been used for getting a QDM. That was a bearing from a ground station, and therefore a heading to steer to get back home. Or, if you had three bearings from different stations you could work out your position. My original question was because I didn't know that radio trainer Proctors had them, until seeing that fine photo of NP229.

I take it that DF stands for direction finding and the loop has to be manually pointed in the right direction?

Sorry for the jargon. Yes Direction Finding. I'm not sure whether the loop was motorised, but I think it was manual.
That's another lovely picture!

I remember a DF in a dome on a DH Heron.It had to be moved by winding a knob to get a Null in the tone from the BFO to get the direction to of from a beacon. IIRC.

I wonder how many pilots today could carry out a let down procedure using a manual loop DF. i.e using the null Lovely to see a dedicated trainer for just that. I was taught to do them by an old Australian Pilot whilst I was operating in the Sahara. Very useful when a ADF signal was weak.

l.garey 19th Oct 2017 16:10

We're a bit off thread for Luton, but I don't mind, having seen those lovely photos of Proctors. At least for a DF let down you would have a navigator to do the twiddling. I still recall how difficult an ADF approach was. I failed my first Instrument Rating because of that. Back to Luton.

Mk5 plus Luton's first control tower.

Bit of a Long Shot but has anyone got a recollection or even a photo of a HP Hermes at Luton?

LTNman 19th Oct 2017 19:30

Closest one I have got is one at Bovingdon.

OUAQUKGF Ops 20th Oct 2017 08:08

LTNMAN can you post your Hermes photo on the RAF Bovingdon in The Sixties thread which you will find somewhere in History and Nostalgia? I would love to see it. Thanks Tom.

It looks to me like a Balliol.

l.garey 20th Oct 2017 13:15

Not a Balliol: it's a Provost alright.

Agreed. The Balliol didn't have a radial engine, for one thing.

l.garey 20th Oct 2017 14:33

Right. A Merlin of all things. Unmistakable. Used to see and hear them growling around Peterborough in the 1950s.

A question: A close relative was telling me that when she was flying back from Switzerland with her children (she lived there) . Her aircraft made the most horrendous landing at Luton. Oxygen masks deployed, passengers told to brace. The engines made quite a noise, passengers got blooded, one chap looked like he had a broken arm and the aircraft nose wheel ended up in the mud. Obviously my relative was more concerned with her young family but she believed it was a Boeing 707 and they were diverted to Luton as their destination should have been Gatwick. It was traumatic and she could not remember the details so well. It may have been 1973. She eventually had her luggage sent to her.

I cannot find a reference anywhere, can anybody help ?

It will be much appreciated.

LTNman 24th Oct 2017 06:15

Only Luton based Britannia Airways operated 707’s and that wasn’t for long. Also a 707 would not be a normal aircraft for that route. I can’t see why any other 707 would want to divert to Luton with its short runway unless the crew had no choice.

The only case I can remember where an aircraft had to divert to its nearest airport that happened to be Luton was when a British Midland aircraft possibly a 737 had double engine problems after take off from East Midlands Airport. I think some seals were missing after maintenance work spilling oil everywhere but that was year later.
