Help needed for 1-11 510ED Autopilot

Post by **MALTBY D** » 14 Oct 2006, 13:13

Thanks very much Peter.
I remember you mentioning the HARCO thing before & that it was very good equipment. Interesting stuff.
I'm going to go for the later BA 510, so it will have the big blank section in the middle of the panel where the map would have once been.
It could well be right that they had also removed the autoland by that point, so I'll have to have a think about that.

With the automatic switching on the A/P, I will just make it work the same as on the Trident model.

I think I've enough info to complete it now. If I find out more over time I can refine it.
Whatever, it will be better for the 510 than the current panel is.

Thanks
David

Chris, I had a look at the 1-11 cockpit shots on Airliners.net & the only ones for sure that have up as 'ON' are the two 510EDs AVMO & AVMU.

There are a number of other marks 200, 400 & 500 all showing down as 'ON'. I'm sure it was the standard fit.
None of the pictures are clear enough to read the panel text, but a trained eye can spot the signs.
The Gen switches is an easy spot, even if you can't read the words you can tell from the size of the words if 'Reset' is top or bottom of the three (Trip, Norm, Reset)

I think on reflection that on is up really was an American thing ; although it has become universally adopted now - but from memory the various European light aircraft ( French and Italian )I flew also were on is up

It's a bit confusing and only seems to bring the Alzheimer's nearer!

On the main panels & pedestal etc., up for 'ON' is normal with all of the British airliners. Trident & VC10 also have up for 'ON' on their overheads.

Why the 1-11 was t'other way round I don't know, but I've not found any but the 510ED (for BEA) that have up for 'ON' on the overhead.
The overhead in American Airlines 1-11 400s was also down for 'ON'. I've got a copy of the manual.
Weird. :think:

Just a guess but Vickers had to modify the Viscount extensively to sell it in the States so perhaps with that experience they decided to make the One-Eleven compatible with what was becoming standard practice.

The Trident and VC 10 were designed for the British State airlines so would be totally British.

The One-Eleven was designed for a wider audience straight off.

As I say just a guess, but that would make the One-Eleven different from other contemporary and previous home grown designs.

Hi Garry,

You have a very valid point there mate. The 1-11 broke tradition by being the first airliner to be ordered by US carriers (from over here anyway) before it was actually built and BAC were keen on giving a very full service and list of options. Switch positions would have been one such option and if it meant securing a sale, then why not

Hi Dave

With the One-Eleven they tried to make it a aircraft for all in it's basic form. So removing one of the major sale hurdles would be a good and cheap mod if done from the desogn stage

A lot of British Independants like BKS were operating early Brit Viscounts alongside ex American fully developed 745D. There was nothing at all compatable making crewing difficult.

Making switch direction universal is a good step in the right direction and a good safety measure.

Ive sat and read this thread with alot of fascination however the "which way" switch problem is not one that is seperated by the Atlantic - there were airlines in the US that requested "reversed" switches - one very famous airline in particular TWA - ALL aircraft post Connie the switches were reversed from US standard to match the Constellations rather odd switching
In fact to this day you can tell an ex-TWA 727/757/MD80 by the switch selection.

Garry you are right.
I was pointing out that Chris' idea that 'up is ON' was an American thing can't have been right - since that's quite normal for Trident & VC10.

But I didn't realize that it must have been the Americans demanding the overhead to be the other way around on the 1-11!
Of course it was. It was the Americans that were mad & prefered down as 'ON'.

Maybe Chris' Alzheimers had in fact arrived & that is what he really meant to say all along.
