Its been some time since flying a 150,but doesn't the airspeed indicator

go out-off-wack when executing a full slip approach.

Patrick.

In a slip the pitot tube is only registering a vector of the forward airspeed
(visualize the forward component of a diagonal "cross wind" on the ground).
More importantly, the static port of the aircraft is now seeing an increased
pressure due to ram air, thus less differential pressure and less A/S reading.
 I did my training in a C-172 and when practicing slips kept the reduced A/S
reading above the stall point knowing that when I let out of the slip I would
have a good safety margin.

Not true on the static pressure. Usually there are static ports
on both sides of the airplane.

The ram air problem is taken care of on experimental air planes
(not the kind we build) by a pivoting pitot tube that points into 
the wind.
