I thought it would be a good idea if there was a single thread for British Instrument documents on the forum as there have been a number of requests over the last year or so for such info.

I am starting with Section IV Altimeters from AP 1275 Aircraft Instruments.

The watermark is to reduce the number of scum websites that steal free content and sell it.

And section 1 - Indicators. Ignore the (Now issued in A.P.1275A) as most, if not all, are in here. I have two other copies of this manual so if you find one chapter missing let me know and I will see if it is in one of the other (tatty and less complete) copies.

Sorry I forgot to finish this as I scanned the manual and have since added two more versions to the collection so I will go back and update and finish what is above. One edition from the 60s only has about 6 chapters.

Also the Polish Air Museum at Krakow has a 1927 version so here that is. The different page sizes are as downloaded as jpgs from their site.

Here is an older one. Officially Amendment 31 but it includes parts of various amendments up to #78.

And I actually remembered to OCR it - that rum liquor I drank just now must have improved my memory
