Here’s my first stoopid question:
I can’t quite get my head around the ASI and why a blocked pitot would indicate a higher IAS. Is it simply that the trapped pressure in the capsule will be expanding against decreasing static pressure outside the capsule like a deflated balloon inflating in a vacuum?
If so does that mean the degree of false IAS reading would depend on the airspeed (and therefore trapped pressure) at the time the pitot became blocked?
