I teach the use of approximately 1/2 spoiler from a point abeam the

Very interesting - I guess you are flying a very tight apporach
pattern, starting very high on downwind, right?

I'm just wonderung, because if we'd do this with the ASK-21 in the
traffic pattern at my home airfield (height at downwind about 650 ft
above ground), we wouldn't even reach the airfield.

LIkely we are teaching a steeper approach profile than you are.
This is because we want pilots used to a fairly step approch on final
to allow shortest landing in a field. It is also easier to judge a
steeper angle.
Pls take the 1/2 spoilers(airbrakes whatever) with a bit of a grain of
salt.
The point is to establish a rate of descent on the order of about
500ft/min
and adjust from there.
