Squat switch locations for stall warning system and landing gear
left wing and left main gear
right wing and right main gear
right wing and left main gear
left wing and right main gear
The squat switch has two functions on the Piper Seminole when it is on ground
Removes power from the hydraulic pump
Deactivates the stall warning
Activates pitot heat
Gives power to the hydraulic pump
If hydraulic pressure is lost, the landing gear
will free fall down
will remain retracted
will get stuck mid extension
will explode
Emergency landing gear extension is limited to
90 kts
The Seminole is equipped with brakes on:
Main landing gear
Nose landing gear
Nose and main landing gear
How many blades does the propeller of each engine has?
This is the capability of a propeller to change the blade angle:
Controllable Pitch
Constant Speed
Full Feathering
How many alternators is the Piper Seminole equipped with?
2, one on each engine
1 on left engine
1 on the right engine
none
This is the capability of the propeller blades to align with the relative wind to decrease drag:
The Seminole is equipped with this type of flap system
Manual
Pneumatic
Hydraulic
Electrical
The landing gear on the Seminole is:
Hydraulically actuated, electrically operated
Manually operated
Electrically operated
Electrically actuated, hydraulically operated
The propeller governor constantly varies oil pressure into the propeller hub to change the propeller blade pitch. This is known as:
The Piper Seminole has the following wing flaps positions:
0
10
20
25
30
35
40
Pitot tube and static port are combined together and located on the:
Left wing
Right wing
Nose
Tail
Regardless of the propeller lever position, what will happen when oil pressure is lost?
Propeller will feather if the RPM are above 950
Propeller will not feather.
Propeller will feather regardless of the RPM
Propeller will feather if the RPM are below 950
The stall warning horn is activated by two lift detectors on the leading edge of the left wing, outboard of the engine nacelle. The inboard detector activates the horn when the flaps are in the
0 and 10
25 and 40
The stall warning horn is activated by two lift detectors on the leading edge of the left wing, the outboard activates the horn when the flaps are in positions
10 and 0
The landing gear warning system will be activated under any of the following conditions:
Gear not locked down with throttle below 15" MP
Gear not locked down with wing flaps selected from 25 - 40 degrees
Gear handle up position when on ground
Airspeed is below 88 KIAS and the gear is up
RPMs drop below 2300 and the landing gear is up
