A320: Unreliable Speed, how to accelerate and clean up?
Hello Guys,
I was recently checking the procedure for unreliable speed in the QRH for aircraft not equipped with the BUSS and assuming you takeoff conf 2, and at 1000 feet you have complete loss of IAS. Ok memory item done, you are now level off with conf 2 at let's say 4000 feet. Now if you decide to divert ( assuming weather is bad at departure airport) what will be your technique to accelerate and clean up the plane? Or even if you could come back to departure airport, how will you descend with conf 2?
Surprisingly the QRH only provides pitch and N1 table for climb, cruise and descent only in clean configuration!?!
I was thinking maybe set Thrust climb, pitch 5° with conf 2 for like 10 seconds then select flaps 1, watch out for VLS and set the pitch & n1 according to the table in QRH for conf 1 and same thing for clean configuration... But that just an idea, don't know how good or bad it is. I would prefer to know what Airbus will recommend us to do, or if none what would be your techniques?
Thank you.
