ARROW I1
INSTRUMENT PANEL
The instrument panel is designed to be functional and professional, accommodating
complete instruments and avionics equipment for VFR and IFR flights. A wide range of
optional instruments and avionics permits an equipment selection uniquely suited to individual
needs.
Flight instruments are grouped in a standard "T" directly in front of the pilot. Radio
navigational indicators are to the right of the flight instruments and are located to correspond to
the respective radio control heads. Fuel gauges are located to the right of the pilot control wheel
and engine instruments are located to the left of the control wheel. The tachometer and
manifold pressure instruments are located to the left of the power quadrant and are positioned
respective of the throttle and propeller controls.
The circuit breakers are protected by a cover door.
The climatic controls, when the air conditioning system is installed, are located in the right
instrument panel above the circuit breakers.
An annunciator panel* is mounted in the upper instrument panel to warn the pilot of a
possible malfunction in the alternator, oil pressure or vacuum systems.
PITOT-STATIC SYSTEM
The system supplies both pitot and static pressure for the airspeed indicator, altimeter and
vertical speed indicator (when installed).
Pitot and static pressure are picked up by the pitot head on the bottom of the left wing.
An optional heated pitot head, which alleviates problems with icing or heavy rain, is available.
The switch for pitot heat is located on the lower left instrument panel.
To prevent bugs and water from entering the pitot and static pressure holes, a cover should
be placed over the pitot head. A partially or completely blocked pitot head will give erratic or
zero readings on the instruments.
NOTE
During the preflight, check to make sure the pitot cover is
removed.
