DH 60 Moth Checklist
Exterior Preflight
1) Inspect airframe for airworthiness
2) Verify adequate fuel and oil aboard
Start Check
1) Fasten Safety Harness
2) Turn fuel tap ON
3) Set
Altimeter to field elevation.
4) With
wheels CHOCKED and Switches OFF, have your Mechanic pull the propeller through
four or five times.
5) On the Mechanic’s command, reach around
windscreen and turn Switches ON. The
engine WILL START when the Mechanic pulls the propeller through with the
Switches ON.
6) Verify
Oil Pressure within 60 seconds
7) Allow the engine to warm up for 3 – 5 minutes depending on
conditions
8) If a magneto check is desired, verify that
the wheels are chocked and have the Mechanic hold the tail. Remember, THERE ARE NO BRAKES.
9) When ready to taxi, have the Mechanic
remove the chocks.
Pre-Takeoff
Check
1) Check
fuel gauge to verify adequate fuel aboard.
2) Recheck
that the Altimeter reads field elevation
3) Set
the Elevator Trim for takeoff
4) Check
Elevator, Rudder, and Ailerons for freedom of movement and that they move in
the proper direction.
5) Check
the area to insure that there is no conflicting traffic. Turn into the wind and smoothly open the
throttle to full power. As airspeed
permits, raise the tail and allow the plane to fly off in a tail-low
attitude. Best rate of climb speed is
approximately 55 mph. Normal climb speed
is between 60 – 70 mph.
Cruise
Normal cruise power is 1800 rpm with either the Cirrus or Gipsy
engine. For maximum fuel efficiency, De
Havilland recommends a true airspeed of 79 mph in Cirrus powered airplanes and
76 mph in Gipsy powered airplane.
Descent
Descents can be made with power off or power on. If making a power on descent, do not exceed
162 mph indicated airspeed. Do not
over-speed the engine. Maximum RPM is
2000 for the Cirrus engine and 2100 for the Gipsy engine.
Landing
1) Overfly
the field to determine wind direction.
2) Enter
the downwind leg at cruise power.
3) Abeam
the touchdown point, close the throttle.
Trim to maintain no less than 60 mph until established on final
approach.
4) On
final, slow to final approach speed.
If
Autoslots are installed, maintain at least 50 mph
until beginning the flare.
If
Autoslots are NOT installed, maintain at least 55 mph
until beginning the flare.
After
Landing
1) When the aircraft has slowed to a safe
speed, exit the landing area.
2) When
you have reached your parking area, allow the engine to cool at idle (600 – 650
rpm) for at least 90 seconds before turning the Switches to OFF.
3) Reset
the trim lever to the index position.
4) When
the propeller has stopped, signal the Mechanic to chock the wheels or exit the
airplane and chock them yourself. DO NOT
LEAVE THE AIRPLANE UNCHOCKED.
5) If
the airplane is not to be flown again, arrange for it to be tied down.
6) Document
any mechanical discrepancies encountered in the aircraft Logbook.

only and must not be used in a real airplane.
