V2 gives you a better climb gradient then V2+20
are u sure about this ? If true, why do we have improved climb?
Retracting flaps means you started the third segmenet...pushing the nose over for a faster speed, a level off...something you might not want to do whilst trying to get over the hills...get it?I
to begin with he has stated that he has achieved the required speed in his aircraft, so why does he need to accelerate! He isn't going to hit the hills.
As the Hawker appears to have 0 flap performance tables, is there any reason why he can't do what he wants in THAT aircraft.
For me, the lack of 0 flap performance information limits what we can do, we have no data to back up the theory that we will get a better gradient with 0 flaps and the appropriate speed and can guarantee obstacle clearance. We also have an issue with the higher speed increasing the takeoff path and possibly encompassing more limiting obstacles.
Noise, not rushing the configuration change, standard sop's across fleets, liability, are all external issues.
