so in scenario 2 a little more speed might help avoid the stall, possibly.
Yes that might be the case, but you should
not IMHO fly your aproach like this and it is
not what I was suggesting, In a Pa28 Warrior for example (With notes I have to hand) the best glide is 73kts with a threshold of 70 but the stall is only 44kts full flap so you could comfortably pull up to 60 kts or less and still have an adequate margin. If you fly your approach fast based on the fact that there
might be wires you are more likely to cock the approach up in the first place. Also, most people seem to agree with my point of go
under the wires rather than over, in which case a high speed is again going to give more problems rather than less.
