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.
