"Andrew Boyd"
Years ago, I was flying a practice ILS 32 in VMC at CYOW in our
Maule:

That's the nicest pic of an (older) Maule that I've ever seen. Nice lines
on a nice ship! Looks like you've moved on to a Pitts...

and I was asked by ATC for "minimum speed" after glideslope intercept.
It was a neat exercise to keep the needles centered under the hood during
the airspeed reduction to 50 mph ias.

I was grinning away because a cold front had passed, and the wind out
of the northwest gave me a nice headwind, so my groundspeed (knots)
was in the high teens, which is probably not something ATC sees every
day on the ILS ... but they did ask for "minimum speed", didn't they? :-)

Yep, they did. The ironic thing is that with the negative or reflex flaps
on my Maule, the easiest way to fly an ILS is to speed up. I don't know if
your Maule had a negative setting but my normal ILS procedure is to fly
cruise or slow cruise until GS intercept, then select negative flaps.
Depending on the RPMs, I get a 600ft/min descent with a touch of up trim at
115 to 125 knots. Fits into traffic real well.

The 80knots would have been a good exercise except that I was almost airsick
from the turbulence. Man, did I want to be on the ground.
