Perf A - "Visual" Departures
Have been told by a pilot of a UK operator which shall remain nameless (but they fly big shiny jets) that their operator has stated that if it is "visual" they can use alternative performance data which ignores the obstacle clearance criteria of Perf A.
Needless to say on certain runways at certain airfields this gives a considerable increase to the RTOW.
I recall that the CAA banned this practice in the early 80's - is it now allowed on JARs then?
It is not a practice that I would be at all happy with - the thought of climbing after take off with an engine out and looking out the window for the "obstacles" frightens me!
Anyone care to comment?
