Cozy MKIV - Third Flight Test Protocol

Third Flight Plan - Engine Performance:

GPS: Set to FIT area - 12 mile range
Radio: Fitchburg traffic, Experimental N83M(ike)Z(ulu) departing runway 32 to the west - Fitchburg.
Throttle: Full - Check for 2300 - 2400 RPM static
Accellerate: To 75 - 80 mph and rotate
Climb: 100 mph straight out to 1000 ft.
Check: CHT / Oil Pressure
Climb: Climb checklist - 100 mph gentle turn to west area to 3000 ft.
Level: 3000 ft.
Throttle: 2200 RPM or to 135 mph (do not exceed 140 mph)
Controls: Check Pitch trim - 80 mph to 135 mph (adjust with throttle); Check roll trim - view ailerons and note position when trimmed for level flight
Radio: Fitchburg traffic, Experimental N83M(ike)Z(ulu) maneuvering at 3000 ft. 3 miles west Fitchburg
