British Instrument documents

[MiTasol]

Next up a partial AP 1095A Aircraft Indicators.

This is a scan from a single sided photocopy that was, from the multiple edge and binding hole shadows, a copy of a copy of the original. It was impossible to work out the original page sizes and the foldouts had been reduced in size to fit the paper at some stage.

It is missing most of the introduction section (Title page, Amendment record, etc) and several sections and pages are missing.

Whereas the US had a single wiring system for all aircraft the British had many different systems, five of which are listed in section 3.

This one is a much earlier version - 1921 - and includes oxygen equipment. Interestingly the Brits were using a lot of liquid oxygen at that stage.
