Piper Arrow II Flashcards
Describe the engine
Lycoming IO-360
Four cylinder, direct drive , horizontally opposed, fuel injected engine
Max gross weight?
2650 lbs
Max horsepower for the engine
200hp
Maximum RPM of the prop
2700 RPM
What is the amperage and voltage of the alternator?
60 amp, 14V
Describe the propeller
Hartzell two-bladed, constant speed, controllable pitch prop
Describe the landing gear system
Retractable tricycle landing gear, hydraulically actuated by an reversible electric pump
What is the approximate landing hear transit time?
About 7 seconds
What area the landing gear max retraction and extension speeds?
125 MPH - retract
150 MPH extension
Describe the nose gear system. How is it operated?
Steed through a 30 degree arc by use of the rudder pedals and brakes. As nose gear retracts, the steerage linkage is disengaged in flight. The nose wheel also contains a hydraulic shimmy damper.
Describe the oleo struts. What is the normal extension.
Air-oil type struts. Normal extension is 2.75” for nose gear, 2.0” for the mains.
Describe the brake system.
Toe brakes on left side rudder pedals and a hand brake. Toe brakes on the right side are optional. Toe brakes and hand brake have individual cylinders but share one reservoir. Single disk, single puck brake mounted on each main gear.
Describe the horizontal stabilizer
Uses a flying tail or stabilator design with a trim tab/servo mounted on the trailing edge.
What is the capacity and useable fuel for the fuel tanks?
25 gallon capacity per tank. 24 gals useable per tank.
How is the alternator protected?
A voltage regulator and an over voltage relay.
What is the voltage if the battery? How many amp hours can it support?
12 volt, 25 AMP hours
What does the vacuum system consist of?
Engine-driven vacuum pump, a vacuum regulator, a filter and necessary plumbing
What type of pump is the vacuum pump
A dry pump
What protects the vacuum pump from damage?
A shear drive
What happens if the vacuum drive shears?
The gyros become inoperative
What is the normal operating range for the vacuum system?
5.0 In/hg +/- 0.1
An unexpected decrease in vacuum system pressure could indicate what problems?
Dirty filter, dirty screens, a sticking vacuum regulator or leak in the system.
What could zero pressure in the vacuum system indicate?
A sheared pump drive, defective pump, a defective gauge or collapsed line
What happens if vacuum system pressure is outside the normal operating range?
Too high - could damage the gyros.
Too low - gyros are unreliable
Where is the vacuum regulator located?
Behind the instrument panel
What annunciations are provided by the annunciation panel?
Alternator, oil pressure or vacuum system malfunctions.
