Autopilot Modes

• Attitude Hold: Maintains a pre-selected altitude automatically by adjusting control surfaces.
• Heading Hold: Adjusts the aircraft's direction by controlling rudder and aileron surfaces.
• Airspeed Hold: Maintains desired speed by adjusting throttle or engine power.

Mode Classifications

• Lateral Modes: Control aircraft movement side to side.
• Vertical Modes: Manage altitude and vertical movements including altitude hold and vertical speed hold.
• Combined Modes: Allow simultaneous engagement of both lateral and vertical modes for flexible flight management.

Sensor Technology in Autopilot

• Pitot Tubes: Measure airspeed and altitude; key for flight safety and performance.
• Static Pressure Ports: Supply static air pressure for altitude calculations.
• Gyroscopes: Detect changes in aircraft attitude (roll, pitch, yaw) for stability.

Global Positioning System (GPS)

• Provides high navigational precision through three operational modes:
  • En Route: Navigation between waypoints during flight.
  • Terminal: Transitioning near the destination airport.
  • Approach: Guidance during final approach and landing.

GPS Components

• Space Segment: Consists of satellites that provide location data.
• Control Segment: Ground-based systems for monitoring satellite status.
• User Segment: Aircraft systems that utilize GPS data.

Enhancement Systems

• Wide Area Augmentation System (WAAS): Improves GPS signal accuracy for various flight phases.
• Inertial Navigation Systems (INS): Combines gyroscope and accelerometer data for navigation.
• Radar Altimeters: Measure altitude using emitted electromagnetic waves.

Additional Avionics Tools
