I think the student will have to unlearn the fast approach technique

fast airplane you have to manage your energy if you want to land on a
small field at the conclusion of the approach.

I only teach in Monneys but I'm not sure why you would need to be
faster without flaps. Even if I used flaps I wouldn't change the speed
on the approach. Are you flying ILSs in a 172 at 50 knots such that
you need flaps?

With the proliferation of VNAV GPS approaches more and more smaller
runways have basically ILS minimums. A typical ILS ends with a 5,000
foot+ runway -- not so for VNAV GPS.

But either way you have full flaps once you go visual so the landings
distance is the same in each technique.

Try this next time -- see what happens to the ILS needles when your
student drops full flaps once the runway is in sight.

Once you're visual holding the needles in the middle is trivial
because you are looking at the runway.

Nope --100-90 KIAS in an A36, 90 KIAS in a 172. Approach flaps set in
the A36 and 10 degrees in 172.

While that may be the case in a particular Mooney or Cherokee or
Skyhawk, this method will not work in a faster (more slippery)
airplane.

Do you ever practice ILS all the way down to touchdown? If not, you
may want to try it -- it's a good confidence boost.

I never noticed that as a problem in the A36. It was very stable at
100 knots without flaps. I never felt any tendancy for it to be
unstable.

What plane are you flying that is more slippery than a Mooney and that
does not slow when you deploy the flaps? Your A36 is a truck compared
to the slippery Mooney. I used to cook into San Jose Int'l in the A36
at 150 knots and drop the gear/flaps on short final. I could feel the
G's of the decelleration, so you can't tell me that your A36 won't
slow with flaps.

Keep in mind -- I never said Full flaps on approach -- only approach
flaps. In most airplanes that's 10 degrees. Full power at the MAP and
the airplane climbs. You climbing? Good -- flaps up. Still climbing?
Good -- gear up.


That's always worked for me, as well.
