Had never done an emergency descent with banking as a tool. *It was
suggested to me to try this with a 90 degree bank.


Very interesting experience as it really works and works quickly! *I
tried 2 without banking and 2 with banking of which the video contains
one of each.


Video contains both outside and instrumentation views but the
instrumentation view unfortunately wasn't as good as I hoped. *Camera
power saving feature shut the camera off and I lost my zoom setting..


Comments here or on the video most appreciated on helping me improve
the technique as this was my first time doing this


Question for you -- What are the Sundowner limits on pitch and bank?


Another speedy way down is a slip of course -- it also allows enough
throttle to keep the engine warm.


I don't have the documentation handy and my memory may be in error,
but I think the Mooney's limits when used in the general utility
category are 30 degrees pitch 60 degrees bank. *Since it's used mainly
for XC, mostly under IFR, there's no reason to ever come close to
those limits. I wondered if the Sundowner certification was markedly
different.- Hide quoted text -

Ah, here it is, and it isn't just Mooneys.

* * * * * a. *FAR Section 91.71 defines "acrobatic flight" as "an
* * * intentional maneuver involving an abrupt change in an aircraft's
* * * attitude, an abnormal attitude, or abnormal acceleration, not
* * * necessary for normal flight." *In addition, Section 91.15(c)
* * * indirectly refers to acrobatic flight in which it specifies that
* * * "unless each occupant of the aircraft is wearing an approved
* * * parachute, no pilot of a civil aircraft, carrying any person
* * * (other than a crewmember) may execute any intentional maneuver
* * * that exceeds:

* * * * * * * (1) *A bank of 60 degrees relative to the horizon; or

* * * * * * * (2) *A nose-up or nose-down attitude of 30 degrees
* * * relative to the horizon."- Hide quoted text -

Another minor issue -- if you are going to do steep descending turns
in a low winged airplane, you may be a little better off making the
turns to the left. Visibility into the space you are turning into
would be better.

Also, question for the readers -- does anyone flying left seat in a
low wing airplane do their slips with right wing low?
