Is there a backup system available if the engine-driven vacuum pump were to fail? (AFM/POH)
This system may be electrically driven or could be an engine-driven vacuum pump running in parallel to the primary pump.
We have electrically driven
Check POH
Interpret the following ammeter indications. (AFM/POH)
Ammeter indicates a right deflection (positive).
After starting —The power from the battery used for starting is being replaced by the alternator. Or, if a full-scale charge is indicated for more than 1 minute, the starter is still engaged and a shutdown is indicated.
During flight — A faulty voltage regulator is causing the alternator to overcharge the battery
Ammeter indicates a left deflection (negative).
After starting — Normal during start.
Other times indicates the alternator is not functioning or an overload condition has occurred in the system.
The battery is not receiving a charge.
During flight —
The alternator is not functioning or an overload has occurred in the system.
The battery is not receiving a charge.
Inside the plane static pressure is usually lower than outside, selection of the alternate static source may result in the following indications:
Altimeter: will indicate higher than the actual altitude
Airspeed: will indicate greater than the actual airspeed
Vertical speed: will indicate a momentary climb then stabilize if altitude is held constant
What instruments may be relied upon in the event of a complete vacuum system failure while operating in instrument meteorological conditions?
The alternator has quit producing a charge,
master switch and the alternator circuit breaker should be checked and reset if necessary.
If this does not correct the problem, the following should be accomplished:
a. The alternator should be turned off; pull the circuit breaker
(field circuit will continue to draw power from the battery).
b. All electrical equipment not essential to flight should be turned
off (the battery is now the only source of electrical power).
c. Land as soon as possible
What action should be taken if the ammeter indicates a continuous charge (right needle) while in flight (more than two needle widths)?
If a positive gear down indication is not received, what action is recommended first? (AFM/POH)
a. Check that the master switch is set to “On.”
b. Check that the “Landing Gear” and “Gear Pump” circuit
breakers are in.
c. Check both “Landing Gear” position indicators by using the “Press-To-Test” feature and by rotating the dimming shutter.
d. If a bulb has burned out, you can use the other operating bulb
as a temporary replacement.
will not extend normally? (AFM/POH)
lf the landing gear fails to extend normally, the following checklist should be completed.
Attempt to extend the gear manually. If this action is unsuccess- ful, plan for a gear-up landing. The following checklist should be completed:
There is a hand-operated pump, located between the front seats,
which may be used for manual extension of the landing gear in the
event of a hydraulic failure.
What is the recommended procedure in dealing with a flat main landing gear tire? (AFM/POH)
a. Establish a normal approach configuration with full flaps.
b. Touchdown with the good tire first on that side of the runway and keep the aircraft off of the flat tire for as long as possible.
c. Use braking on the good wheel as required to maintain
directional control.
What is the recommended procedure to follow if the nose gear is unsafe or the tire is flat? (AFM/POH)
Why should taxiing on a slush, snow, or ice covered taxiway in retractable gear airplane be avoided? (AC 91-13)
mud and slush can be thrown into wheel wells
If it then freezes during flight creates landing gear operational problems.
1.What is an “asymmetrical” flap emergency?
What procedure should be followed in an asymmetrical flap emergency? (FAA-H-8083-3)
What procedure should be followed if loss of elevator control occurs? (AFM/POH)
a. Extend the landing gear.
b. Lower flaps by 10°.
c. Set trim for level flight.
d. Using throttle and elevator trim control, establish an airspeed of 70 knots.
Do not change the established trim setting.
Maintain control of the glide angle by adjusting power.
At the landing flare , the elevator trim should be adjusted to full noseup and the power reduced.
A the moment of touchdown, close the throttle.
Don’t allow anyone to attempt to close the doors while in flight.
By design, the baggage compartment door will tend to remain closed during flight due to airflow pressure.
What two factors should be considered in choosing the type of survival equipment to carry for a flight over an uni nhabited area? (AIM 6-2-6)
Approved flotation gear for each accupant
and at least one pyrotechnic signaling
