List members,
The first flight of N613BX
was done this morning and went off as planned. The density altitude was
8700 ft.
The flight time was 32
minutes. I did some turns up to 30 deg bank after climbing to 9500 ft,
set up descents with half and no flaps to get 80 Kt and 300 fpm descent rate to
determine the power settings for this. Then I did a couple of stalls, one
with no flaps and one with half flaps. The indicated airspeeds for the
stalls were around 58 and 50 Kt respectively with the power setting close to
that determined for the descents. Then I made one approach and landing
with no flaps.
I think I am overpropped,
but it still flies!
I have not contributed much
to this list, but I have benefited from it greatly. My thanks to you all.
