2. The best speed for take-off is about 60 MPH under normal conditions.
Trying to pull the airplane off the ground at too low an airspeed decreases
the controllability of the airplane in event of engine failure.
3. Flaps may be lowered at airspeeds up to 115 MPH. To reduce flap
operating loads, it is desirable to have the airplane at a slower speed
before extending the flaps.
4. Before attempting to reset any circuit breaker, allow a two to five minute
cooling off period.
5. Before starting the engine, check that all radio switches, light switches,
and the pitot heat switch are in the off position so as not to create an
overloaded condition when the starter is engaged.
6. The overvoltage relay is provided to protect the electronics equipment
from a momentary overvoltage condition (approximately 16.5 volts and
up), or a catastrophic regulator failure. In the event of a momentary
condition, the relay will open and the ammeter will indicate "0" output
from the alternator. The relay may be reset by switching the ''BATTERY''
switch to "OFF" for approximately one second and then returning the
"BATTERY" switch to "ON."
7. The vacuum gauge is provided to monitor the pressure available to assure
the correct operating speed of the vacuum driven gyroscopic flight
instruments. It also monitors the condition of the common air filter by
measuring the flow of air thru the filter.
If the vacuum gauge does not register 5" + 0.1" Hg at 2000 RPM, the
following items should be checked before flight:
a. Common air filter, could be dirty or restricted.
b. Vacuum lines could be collapsed or broken.
c. Vacuum pump, worn.
d. Vacuum regulator, not adjusted correctly.
