But that is a side effect of flaps. So what you are saying is that they had planned their pattern assuming they would be able to extend flap on final but couldn't and ended up too high?
I assumed they came in a bit too high as an insurance (you can burn height but can invent it), but just ended up with a lot more than they expected just because if their lack if familiarisation with the situation in that plane, so much that the dive break alone weren't sufficient to burn it.
- FabHK 10y agoYes, typically you'd want to come in a bit high (or fast; you can always trade speed for altitude to an extent). Then, you put in flaps to have a less efficient wing profile and descent more steeply (without gaining excessive speed). However, here they did not have enough power to do that, so the Captain put it into a slip: flying uncoordinated, with (say) left rudder, but right aileron, flying somewhat diagonally (or rather, flying straight ahead still towards the runway, but presenting not only the nose, but a bit of the aircraft body to the wind). That gets you down quite well. Those are really the techniques when you're too high on the approach: 1. Flaps 2. Slip 3. S-Turns
