Commercial precision landings
I like 1.5 Vs until on final, that provides a good margin
for maneuvering with bank angles up to 30 degrees. Yes you
can calculate the proper speed, Beech does have the proper
speeds on their performance charts, adjusted for actual
weight.

Vsx gear up.

| You are likely flying too fast and too wide on downwind.
| You are also probably watching your gauges and airspeed
as

sound

and

Make
| sure you know the procedure and have checked during the
| pre-flight that the gear handle can be un-stowed
[sometimes
| the spar cover is installed over the handle]. But also
| remember that it take 50 turns to get the gear down and
you
| only have so much time. If he gives you a simulated
engine
| failure and then the gear fails, exercise your judgment,
| tell him that in a real case you'd land gear up rather
than
| risk a crash while trying to crank the gear. Then add
power
| and go-around, crank the gear on downwind to show him
you
| know how. Sometimes an examiner will give you a task to
see
| if you have fixated on the checkride and not the safety
of
| the flight.
|
| Jim, is there any speed that is best to fly when cranking
the gear down
| by hand?
