5. There's always sufficient engine start pressure although no external air is connected. See the "Engine Start Air Pressure Indicator", No. 7 gauge http://img403.imageshack.us/img403/4472/startpressureind.th.jpg http://img840.imageshack.us/img840/707/startpress.th.jpg

According to my 707 manual, this is the rudder hydraulic pressure gauge, and not the engine start air pressure indicator. There is also mentioned such a engine start air pressure indicator in my manual,  but it has got a different scale than the gauge we got in our 707. The one in our 707 has exactly the same look and scale like the rudder hydraulic pressure indicator in my 707 manual. So if there is enough hydraulic pressure, the needle should be in the green band. If no pressure, of course, it should show less or 0 if no pressure is available...

Just by the way: Great work here!  :D I'll check the frequency control knobs for each generator on the electrics panel, I dont think they're working... And of course will check the radar.
