Why Are Aircraft Instruments Important?
- Critical flight information
- safety and efficiency
- navigation and maintaining control
Standard set of instruments found in most aircraft. Essential for understanding and controlling the aircraft’s status: These
instruments provide critical information for flight operations.
The Primary Flight Instruments (“Six-Pack”)
Measures the speed of the aircraft relative to the surrounding air: Displays how fast the aircraft is moving through the air.
Airspeed indicator
Shows the aircraft’s orientation relative to the horizon: Indicates pitch and bank.
Attitude indicator
Measures the aircraft’s altitude above sea level: Displays height above a set reference point.
Altimeter
Indicates the rate of climb or descent: Shows how quickly the aircraft is gaining or losing altitude.
Vertical Speed Indicator
Displays the aircraft’s heading or direction: Shows which direction the aircraft is pointed relative to magnetic
north.
Heading Indicator
Shows the rate of turn and roll: Indicates how fast the aircraft is turning and the degree of bank.
Turn Coordinator
Refers to electronic
displays and systems that provide flight information through digital readouts, typically on LCD screens.
Digital Instruments
Combines essential flight information such as airspeed, altitude, attitude, and heading into a single screen.
Primary flight display
Provides navigation data, weather information, engine parameters, and other crucial flight data.
Multi-function display
Digital displays for engine performance, fuel management, and system health.
Engine Monitoring System
Advantages of digital instruments
- Increased Accuracy
- Enhanced situational awareness
- Ease of interpretation
- Improved reliability
