Arrow

The Wing is of a conventional design semi-tapered and employs a laminar flow.  The stabilator incorporates an anti-servo tab which improves longitudinal stability and provides longitudinal trim.  This tab moves in the same direction as the stabilator, but with increased travel. 

Each wing contains one fuel tank.  The flaps are 4 position wing flaps mechanically controlled by a handle located between the front seats.  When fully retracted, the right flap locks into place to provide a step for cabin entry. 

Lycoming - IO-360-C1C6 four cylinder - IO stands for Injected & Opposed

Horizontally opposed

Air cooled

Normally Aspirated

Direct drive

The Arrow is equipped with a retractable tricycle landing gear, which is hydraulically actuated by an electrically powered reversible pump. 

For Emergency gear extension, the emergency gear lever, located between the front seats to the left of the flap handle, must be held in the down position to manually release hydraulic pressure and permit the gear to free fall.  The nose gear is spring assisted.

Gear down and locked positions are indicated by three green lights located to the left of the selector.  A red WARNING GEAR UNSAFE light located at the top of the panel, illuminates while the gear is in transit, or not in the full up or locked down position.  An all lights out condition indicates the gear is up.  The landing gear should not be retracted above a speed of 107 KIAS and should not be extended above a speed of 129 KIAS. 

A micro-switch in the throttle quadrant activates a warning horn and red WARNING GEAR UNSAFE light under the following conditions:

a)  Gear up and power reduced below approx. 14 inches of manifold pressure.
b)  Gear selector switch UP while on the ground and throttle in retarded position
c)  Whenever the flaps are extended beyond the approach position (10 degrees) and the landing gear not down and locked. 

The Arrow is equipped with oleo struts of the air-oil type with normal extension being 2.75 +/- .25 inches for the nose and 2.5 +/- .25 for the mains. 

On the left side of the fuselage is a pitot static system which when connected puts the gear down at a certain airspeed.  We do not have the feature turned on.

BRAKES

The Arrow is equipped with hydraulically actuated disk brakes on the main landing gear wheels.  Braking is accomplished by depressing the tops of the rudder pedals.  The hydraulic system for the brakes is independent of that for the landing gear.  To set the parking brake pull back on the lever and depress the knob attached to the top of the handle.  To release the parking brake, pull back on the brake lever; then allow the handle to swing forward. 

FLAPS

The Arrow is equipped with a manual flap system.  The flaps are extended with a lever located between the two pilot seats.  Flap settings are 0, 10, 25, or 40 degrees of flaps. 

VACUUM PUMP

The Arrow is equipped with one engine driven Vacuum pump.  The vacuum system operates the attitude and directional gyros.  The vacuum pump is a dry type pump which eliminates the need for an air/oil separator and its plumbing.  A shear drive protects the engine from damage.  If the drive shears the gyros will become inoperative.  Normal range is 4.8-5.1 inches of mercury.

PITOT STATIC SYSTEM

The heated pitot tube is located on the bottom side of left wing.  The static port (1) is located on the pitot tube.  Push button type drains are located on the lower left side of the cockpit.

FUEL SYSTEM

The Arrow, which uses 100 low lead avgas (blue), is equipped with two 38.5 gallon tanks.  2.5 gallons is unusable in each tank.  Therefore there is a total of 77 gallons and only 72 gallons are usable. 

Each tank is equipped with a filler neck indicator tab to aid in determining fuel remaining when the tanks are not full.  Usable capacity tab to the bottom of the indicator tab is 25 gallons.  The tanks are vented individually by a vent tube which protrudes below the bottom of the wing at the rear inboard corner of each tank. 

Normally fuel is supplied to the engine through an engine-driven fuel pump.  An electric fuel pump serves as a back-up feature and is used for engine start, takeoff, landing, and fuel selector changes. 

ELECTRIC SYSTEM

The Arrow is equipped with a 14 volt electrical system which utilizes push-pull type circuit breakers: a 12 volt, 35 amp hour battery ; and a 60 amp engine driven alternator with a voltage regulator and over voltage protection.

The airplane has two buses -  a main bus and an avionics bus 

HEATER

An opening in the front of the lower cowl admits ram air to the heater shroud and then the air is ducted to the heater shut-offs on the right and left side of the firewall.  When the shut-off's are opened the heated air then enters the heat ducts located along each side of the center console. 

PIPER EXTERNAL POWER

An optional starting installation known as Piper External Power (PEP) is accessible through a receptacle located on the right side of the fuselage aft of the baggage compartment door.  An external battery can be connected to the socket, thus allowing the operator to crank the engine without having to gain access to the airplane's battery.
