Phrase "landing runway" vs. "cleared to land"

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?

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


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

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.

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.

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.

The A56 drag coefficient is a bit more than a Lear and an F-104, so
it's pretty slippery.

In the Army we differentiated between doctrine and technique. Doctrine
everybody was to do, period. Technique was the method you employed to
achieve doctrine.

In this case "doctrine" is to arrive at the runway with as little
energy as possible, given the requirements of safety in the conditions
at hand.

If you can reconfigure the airplane on short final and reduce the
speed as appropriate to achieve this, then that's your technique.

But I think teaching this particular method as the only way for every
airplane is a mistake, as it will eventually lead to overly fast
landings when the student climbs aboard his/her faster airplane.

It just seems to me that a consistent, less drastic change in
configuration is the better technique.

True, but its still a truck compared to a Mooney.

I think anyone who teaches either technique and claims its good for
all aircraft is probably full of crap. I wouldn't teach flying
approaches w/o flaps in a 767. When I'm giving training in the Mooney
or occasionally in the A36 people are looking for type specific
training. Showing them how its done in other aircraft (like a 767) is
not what they are looking for. In both those aircraft I find the no
flap approach best. Add to that that I live in a fog valley and
finding nothing but 0/0 at mins is not uncommon so shooting approaches
to mins in actual is not theory around here and neither are missed in
actual.

Wel, as a matter of fact, we do have to do that....

So, you are able to:
Apply full flaps
Reduce speed from 90-100 K to 70 K
Continue descending to the touchdown point
Stabilize the approach at somewhere near 1.3-1.4 Vso
All beginning at 200' AGL?
