	GPS Groundspeeds Measured (mph)			True Airspeed		CalibratedVc
Target AS	V1	V2	V3	mph	knots	knots	mph
170	185	189	188	187	162	150	172
150	160	154	167	164	142	132	151
130	138	136	146	142	124	114	131
110	117	130	124	121	105	97	112
90	96	109	103	100	87	80	92
70	77	74	84	81	70	65	75

In the table above, the first column and the last column are the ones of interest, showing the target airspeed and the calibrated airspeed, with the difference being the error of the airspeed indicator. Not too bad - at anything over 90 mph, the error is within 2 mph.

Throttle:	1400 RPM - descend to pattern altitude
Approach:	Use landing checklist - maintain 100 mph downwind / base, 90 mph final, extend landing brake on final, touch down 75 - 80 mph.
