Default Approaches & Landings (a Creeping Thread...)


"Bob Whelan" wrote in message
...

By way of conclusion, here's a thought problem for some dogmatic readers.
I no longer worry about not having a slip in the landing arsenal of the
ship I have most of my time in. Oh, it'll slip just fine, but its descent
rate in a non-turning slip is significantly less than what it generates in
the slip's absence. How can this be???

Regards,

Check the LS-4 Pilot Handbook. It says that slips with full airbrake are not
so effective because airbrake causes a strong nose-down pitching moment, and
airspeed increases excessively.

In practice, I have found this to be so---Full airbrake alone produces a
steeper approach than full airbrake plus slip.

Is that the case in your ship?
