Section 5 - First Flight
The first flight must not be attempted unless every detail of the installation has been
accomplished in strict compliance with this manual and the pilot is thoroughly familiar
with the standard operating procedures as defined in section 4.
|If any procedure specified in this section conflicts with
recommendations of the aircraft or engine manufacturer, then those recommendations should
take precedence over contrary instructions contained herein.
During the first flight the pilot should have available a pencil and the flight test
log sheet included as Appendix B in this manual for recording
flight test data.
|If at any time during the following procedures the engine
or flight instruments give readings that are outside of acceptable limits, the flight
should be discontinued.
1. Preflight the aircraft in accordance with normal preflight procedures.
2. Start the engine in accordance with section 4 of this
3. Complete the normal engine run up and pre-takeoff check lists. Prior to brake
release, check engine instruments to determine that full takeoff power is available. The
take off should be accomplished with the mixture in the full rich position and the
induction heat off.
4. Climb to an altitude that is comfortable for normal cruising flight and reduce
throttle to cruise power. After trimming the aircraft for hands-off level flight, allow
enough time for the aircraft's speed to stabilize, then record the data requested on line
1 of the flight test log.
5. While at the same altitude and power setting as above, carefully lean the mixture to
peak RPM or peak EGT if a constant speed propeller is installed. If RPM or EGT begins
decreasing as the mixture is leaned, then the full rich mixture setting is too lean.
Discontinue the flight and repeat section 3-3 of this manual. After 5 minutes of hands-off
stabilized level flight, record the data requested on line 2.
6. While at the same altitude and power setting, slowly lean the mixture to the
threshold of engine roughness. Record on line A the RPM (or EGT) at which roughness is
first noticed and then return the mixture to full rich.
7. While at the same altitude as above, advance the throttle to wide open. Adjust
mixture to 50 RPM (50 degrees EGT) on the rich side of peak, Trim the aircraft and allow
time for the aircraft speed to stabilize. Record data required on line 3.
8. Climb to 7000 feet leaving the mixture control set as directed in step 7 above. Trim
for hands-off level flight at full throttle, and allow time for speed to stabilize. Record
data on line 4.
9. While at the same stabilized flight condition, lean mixture to peak RPM (EGT).
Record data on line 5.
10. At the same stabilized flight condition, lean the mixture to the threshold of
engine roughness. Record the RPM (EGT) at which this occurs and then enrich only as
necessary, just to restore smooth operation. Record data requested on line 6.
11. Position mixture control to FULL RICH prior to descent.
12. After landing retard the throttle to idle while mixture is full rich. Record idle
RPM on line B.
13. With brakes on, and tail tied down, set the engine speed at 1000 RPM and perform a
"jam" acceleration. Note behavior on line C of the test flight log.
Following completion of the above test, fill out all remaining portions of the flight
test log sheet. The original should remain with the aircraft log book and a copy
must be returned to Ellison Fluid Systems, Inc.
