speaking of buggered ASI, had an interesting one in an Arrow, accelerated down the strip, asi working well, 70 kts rotate, climb at 80, then 90 then 110 then 140 then 180, the ASi kept on winding up! well past redline then back around for another lap. the needle then came back to 200kts then to the stop, then back to 80 kts, then back to the stop, one busy and confused Bug going for a walk along the Pitot system. completed a circuit and touchdown at 170 kts! what this has to do with intersection departures umm, i dont know.
