T1-1
Section T1 - Taxi Tests.

Start engine and verify proper engine and systems operation following POH procedures.
CAUTION: Rapid application of throttle or high RPM may lift canopy open
CAUTION: RPM should remain below 2500 RPM until the oil temp has risen above 122
o
F.
For iS engines, a short duration above 2500 RPM (up to 5 seconds) is allowable to engage
generator (see POH checklist).

Verify that brakes can hold the aircraft stationary with power at up to 2500 RPM.

Taxi slowly and make sure that brakes are functioning and that the aircraft can easily be
brought to a full stop.

Taxi slowly and verify that the aircraft tracks straight with rudder held straight and without use
of brakes. (This must be done on a level taxiway and with less than 5 knots wind)

Verify that, when taxiing at 15 kt or faster, aircraft can be steered using rudder only and no
brakes.

Verify that with one brake locked, the aircraft can be pivoted or spun 360 degrees on one
wheel. Perform this task in both directions.

Latch Canopy.

Once oil temperature has reached at least 122 degrees F [50 º C], perform a 4000 RPM run-up
and verify that the brakes can hold the aircraft stationary.

Verify that the aircraft can be held stationary with the engine at full throttle. If unable check
again after brake conditioning procedure and add ballast weight if necessary.

Taxi at progressively higher speeds up to but not exceeding 25 knots. At each speed, verify
that aircraft can be accurately steered using only rudder and that the aircraft can be rapidly
brought to a stop while tracking in a straight line. Pay attention to the amount of rudder input
necessary to counteract engine torque and to keep the airplane straight on the runway.
Watch out for rapid applications of throttle at low speeds.

Perform brake pad conditioning per Brake Manufacturer instructions then let brakes cool for
five minutes.

Perform magnetometer calibration according to EFIS manual.

Shut down engine per following POH procedures.

After shut down move the aircraft approximately 3 aircraft lengths by hand to verify that both
brakes are fully releasing and are not dragging.
