Atr72
Hi folks
Even though these questione have been asked in the past, i was not able to locate the proper answers.
In the atr72 and bear in mind that i do not fly turboprops even though i am a huge fan of the atr, why do you have to increase the prop from 77 to 86%Np when you use the anti-ice system - if i am nt mistaken the props are left in the AUTO detent corresponding to 77%Np setting throughout the flight?
does it have to with the performance of the airplane or is it related to the load on the pneumatic system or else?
With reference to the atr crash a few years back in the chicago area due to icing accretion behind the boots, how did that result in a hinge moment reversal? My guess is that the ridge would have caused the detachment of the boundary layer across the top surface of the wing, causing the aileron to flutter and not in a full hinge reversal, but i guess the facts prove my theory wrong!
Finally why is it now recommended to hold in a clean configuration?
Kind regards
