"Hi guys, my sensors are giving inconsistent airspeed indications.
Everything else seems OK, so I'm going to fly pitch and power until I get things sorted out"
This wise in almost every case.
But what if (unknown to yourself as you are receiving conflicting information) you are in a deep stall with idle thrust and you now increase the thrust to, say, 83%?
(NB: I realise you would have had to have been asleep to jump from normal flight to a deep stall without noticing something was awry).
