Systems Flashcards
The Lance’s wing is of what design?
Conventional design, rectangular in shape. The shape allows the wing to stall from the wing root to the tip, this is to ensure more controllability as the aircraft stalls.
Does the lance have ailerons that hVe differential deflection?
Yes, these ailerons reduce adverse yaw in turning maneuvers. The downward aileron has less deflection.
Describe the engine of the Lance.
Air cooled IO-540, with a fuel injected 6 cylinder horizontally opposed engine at 300 HP at 2700 RPM. The engine has single drive dual magnetos with an induction scoop.
If during the mag check on run up, the tolerances are exceeded or there is no RPM drop, can you still depart?
No, the ground wire off the ignition switch is not grounding. It could also be that the magneto timing is set in advance of a specified firing time.
What kind of prop does the lance have?
3 bladed Hartzell that is non feathering constant speed prop. Pitch is regulated by the prop governor.
What is prop overspeed?
Usually involves a runaway prop as the governor malfunctions, or low oil pressure. If such a scenario is encountered try to maintain pitch at 2700 RPM.
How many gallons of usable fuel does the Lance have?
94 gallons.
How many gallons per hour does the Lance typically burn?
20 gallons per hour.
How many fuel pumps are onboard the Lance?
2 one engine driven, the other electrically driven.
Can you use and MEL to depart with one of the fuel pumps inoperative?
No, neither can be deferred with an MEL.
How is fuel delivered to the cylinders?
Through a fuel pressure fuel flow gauge/divider, and into the cylinder via a fuel nozzle. 12 - 18 psi on start and the. 12 - 40 during normal operations.
In Lauren’s terms describe the Piper Lance
Single engine, retractable gear, all metal aircraft made of an aluminum alloy. The wing structure is rectangular.
How many qts of oil are in the Lance?
12 13 with the filter.
What is the minimum allowable oil for flight?
2 3/4 qts oil.
What is the maximum oil temperature allowed?
245 degrees.
What is the pressure range for normal operations concerning oil?
25 - 100 psi.
How many volts and amps does the Lance battery have?
12 volt battery, with 35 amps for one hour.
How many volts and amps does the electrical system usually run?
14 volt system with 60 ampere alternator.
What is the normal tire pressure on a Lance?
35 in the nose 38 in the mains.
How are the gear actuated in the Lance?
Activated electrically and actuated hydraulically.
How are the landing gear held up during flight?
With hydraulic pressure.
How are the gear held down and locked?
With mechanical locks.
Where is the squat switch located?
On the left main gear torque link strut. This switch remains open until gear are fully extended.
What kind of brakes does the Lance have?
Cleveland double disc hydraulically actuated brakes that have a common reservoir.
