It appears that incorrect airspeed indications almost brought the Wellesborne-based Avro Vulcan to grief during a fast taxi test in September.
The ASI normally used to ascertain the aircraft’s speed is the one fitted in the P2 position, so P2 calls the speed for the P1. That Air Speed Indicator (ASI) stuck, and by the time the P1 realised it the vintage jet was simply travelling too fast at the normal turn off point. The P1 turned the aircraft left after departing the runway to parallel the hedge, and the Vulcan departed eventually stopped next to the airfield perimeter. No one was hurt and the aircraft was undamaged.
