Hi

So this brake pressure gauge,

It has three needles. The port and starboard needles rise together provided there is sufficient hydraulic pressure? the outer needele gives and indication of total hydraulic pressure in the brake system? ie port brake plus

From 'The Spitfire Mk.V Explored'

"A triple pressure gauge, showing the air pressure in the pneumatic system cylinders and at each brake, is mounted on the left side of the instrument panel."<div class="ev_tpc_signature">

That looks like a great CD. I saw it on sale at RAFM Hendon but went for the books instead. Im a bit surprised that its a pnuematic system rather than hydraulic.

Very well found.

Is ther any indication as to what the MKIC means?<div class="ev_tpc_signature">

This is similar to the guages on a cargo truck with airbrakes. "Supply Air" is the amount of air contained in the air tanks, supplied by an engine-driven compressor. The Port and Starboard readings would be "Application Air", or the amount of pressure supplied when the brake pedal(s) are depressed to send air to the diaphrams that activate the respective brakes.

Interesting...I knew the flaps were pnuematic, but I never realized the brakes were as well.<div class="ev_tpc_signature">

Well, the gauge shown on the cd is similar but not identical to yours, in that the numbers are slightly different, and has 'Mk.I' written on it. So, it could be the 'mark' of gauge, or mark of aeroplane?

Short answer - sorry, I don't know.

Brakes, Flaps, Guns, and Camera appear to be pneumatically operated on the Spitfire.<div class="ev_tpc_signature">
