Sorry to be a pain, but I'd appreciate advice on the test for leakage of air to these devices (EFIS and my steam gauges)
Pumping up my ASI to 130 knots leads to a rapid leakage (5 seconds from 120 to 110 knots) until the pressure has reduced to an indication of 100 knots or so at which point the leakage becomes slow, probably an exponential improvement.
Similarly, sucking out air from one static port (with the other blocked) leads to rapid leakage from 1100 to 900 feet, then dramatic improvement in the leakage rate.
Is this normal? Or should I expect essentially no leakage at any pressure?
Cheers...Keith
