Introduction
Aircraft instruments are the instruments that provide the pilot with information about the flight situation of that aircraft, such as height, speed and altitude. The flight instruments are of particular use in conditions of poor visibility, such as in clouds, when such information is not available from visual reference outside the aircraft.
Airspeed Indicator
The airspeed indicator or airspeed gauge is an instrument used in an aircraft to display the craft's airspeed to the pilot.
Airspeed Arcs
What does each colored arc mean?
White Arc?
Flap Operating Range
Green Arc?
Normal Operating Range
Yellow Arc?
Caution Range
Red Radial Line?
Never Exceed Speed
Altimeter
Altimeter is indicates an estimated height above sea level .
Static Input Only.
Manufacturer seals the aneroid wafers at a specific pressure. As the static pressure fills in the area around these sealed wafers, they will be able to contract or expand accordingly.
Altimeter Operation
It senses pressure changes.
With changes in pressure aneroid wafers will expand and contract, which turn the pointer on the altimeter.
As the aircraft moves into lower pressure a climb is indicated.
As the aircraft moves into higher pressure a descent is indicated.
Attitude Indicator
An attitude indicator (AI), also known as gyro horizon or artificial horizon, is an instrument used in an aircraft to inform the pilot of the orientation of the aircraft relative to earth. It indicates pitch (fore and aft tilt) and bank or roll (side to side tilt)
Conlusion
At the conclusion ,at the time of flight training by using this instruments the pilot should be able to fly the aircraft consistently within its limitations, know when to use its systems, determine if those systems are operating properly, be able to use its navigation, flight instrumentation and autopilot systems efficiently and be able to fly the aircraft safely.
