and whether the aircraft will be able to be set up in time (ie is it fixed u/c as, if not, that can mean a safe wheels-back-down landing may not be possible).
Number one point. It should be hammered home during complex type SE training NOT TO RAISE THE GEAR UNTIL NO USEABLE RUNWAY REMAINS! (If you'll pardon the double negative)
Number two point. In order to safely conduct this exercise, from a point when you are actually airborne in a climb, probably requires a runway of around 2,000 metres. There aren't that many that long in the UK, where SE training takes place.
Number three point. The standard call to ATC when conducting a simulated engine failure after takeoff is 'fanstop'. to which the response is 'roger, report climbing away'. As has been said elsewhere, it seriously diminishes the training value of a simulated EFATO if the student knows about it beforehand, by way of other communication with ATC.
Number four point. The best place to carry out your practice PFL down to a landing is from the aerodrome overhead. We even used to manage this at an aerodrome in the London area which was partly embedded in what was then Class 'A' airspace.
