- not in a Turbulent. Airflow noise is about all you have (long silk scarf and open cockpit sometimes helps ). I once did a post C of A airtest on an Auster, which as usual involved a dive to published 'Vne' which I think was around ?120mph? (long time ago!). With full power and about 30 degrees nose down and 105 on the ASI and a hairy Yorkshire engineer urging me to ' **** get the speed up' (yes, I got him to fly on the AirTest!!) I quit, since it 'sounded' bleedin' fast. Turned out there was a large 'ole in the ASI tubing and Lord knows what we were up to!500N wrote:If the pitot tube is covered, is their any other way of telling what speed the aircraft is doing ?
This was after I had embarrasingly spun round on the grass trying to taxy since a brake had stuck on...............
