Hello everyone....I'm looking for the air speed correction chart for the early Avengers.
This isn't for an early Avenger, but since nobody has replied, and on the theory that something is better than nothing, here are the airspeed installation correction tables for the TBM-3:
Flaps and landing gear retracted
100 knots, subtract 4 knots
140 knots, subtract 3 knots
180 knots, subtract 2 knots
220 knots, subtract 1 knot
Flaps and landing gear extended
70 knots, subtract 6 knots
80 knots, subtract 6 knots
90 knots, subtract 4 knots
100 knots, subtract 4 knots
110 knots, subtract 3 knots
