Brief Description: 8th Flight (2). AOA Calib, Cruise Perform data
|
|
Conducted 2 flights.
1st Flight: Evaluated final rudder trim size. Found to be perfect.
Performed AFS AOA calibration. Doing the "0 G" calibration manuver starting at 90 mph - flaps down, was "interesting". Final results are good with stall occurring just after the 3rd red light comes on. Conducted glide testing different speeds, all at Idle power:
70 mph: 680 FPM
75 mph: 850 FPM
80 mph: 870 FPM
90 mph: 1000 FPM
2nd Flight: Engine reliability testing, EFIS Map use and NavAid AP-1 Tracking.
During flight at 10,500 ft headed toward Tillamook, noted the alternator dropped out!, Made sharp 180 turn back to Aurora and on roll out, power came back. Off line about 1 min. Continued flight for 2 hrs and had no further issues. Cruised race track between Hillsboro to Independence at 9500 ft. (12,600 ft Density Altitude) 65% power & (FT & 2300 RPM), leaned to 50 Deg rich of peak, 8.5 GPH, 181 MPH TAS. Increasing RPM to 2500 only increased speed to 185 MPH, increased fuel flow to 9.7 GPH! Very little "bang for the buck"!
Starting to understand use of the EFIS map function. Engaged AP-1 Autopilot to EFIS, but tracking would hunt back and forth across the course. Obviously have some calibrations yet to do.
OAT on landing at 1400 hrs was 97.... OAT taxiing on the asphault was 117!!
After flight, permanently glued rudder trim piece to rudder trailing edge.
