Not meaning to cause trouble but...
Where have I stated that?,
quote from MJ:
They also don't have a hope in hell of making the field if the donk goes because they are on a shallow approach.
I tend to teach slightly steeper above the 3 degree approach. Most light singles glide around 5 degrees, so surely anywhere between 2 and 5 should be acceptable? I certainly don't teach students to follow the PAPIs or ILS, as you will end up landing deep into the runway. As long as you are teaching the visual aspect and touchdown somewhere close to the beginning of the runway, does the steepness of the approach matter that much? I've seen perfectly well flown 2, 3, 4 and 5 degree approaches, if it's a viual approach it shouldn't matter (taking any obstacles into account).
