Received my first speed restriction

"Peter R."
Yesterday, while wrapping up my complex, high performance instruction in a
Bonanza V35, I received my first speed restriction from ATC during the
approach back into the class C airport. "Bonanza XX, do not exceed 150,
number two following a Dash 8, cleared ILS 28 approach."

Congrats!

My one and only speed restriction (at HPN) went like this "Maule, how slow
can you go?", "80 knots", "...reduce speed to 80 knots, your number 2 behind
blah blah". What a mess. I did it but it didn't matter... got a missed
approach on short final.

The controller appeared to be handling, or perhaps coordinating a lot of
traffic with other controllers. In any case, he was using speed changes and
restrictions to manage it instead of vectors. Problem was that my
groundspeed varied about 30 knots throughout the approach. I'm sure that
everyones elses did too. Embedded, low energy cells seem to alternately
cause headwinds and tailwinds. No way that airspeed management would work
on such a day.

The 'Bo sounds nice. Hope to get the chance one day.
