Study Notes
Autopilot Systems
- Definition: Automatic flight control system that uses sensors and computers to control the aircraft's flight trajectory
- Types:
- Single-axis autopilot: Controls one axis of the aircraft (e.g., altitude)
- Two-axis autopilot: Controls two axes (e.g., altitude and heading)
- Three-axis autopilot: Controls all three axes (pitch, roll, and yaw)
- Functions:
- Altitude hold
- Heading hold
- Navigation (e.g., GPS, route following)
- Autoland (automatic landing)
Cockpit Design
- Human-centered design principles:
- Ergonomics (comfort, accessibility)
- Visibility (instrument placement, minimal distractions)
- Usability (intuitive controls, minimal complexity)
- Key components:
- Flight deck (cockpit layout, instrument panel)
- Pilot interface (displays, controls, and alerts)
- Crew resource management (CRM) principles
Flight Instruments
- Primary flight instruments:
- Airspeed indicator
- Altimeter
- Heading indicator (compass)
- Turn coordinator (bank and turn rate)
- Navigation instruments:
- Horizontal situation indicator (HSI)
- Navigation computer
- GPS navigation
- Engine instruments:
- Engine speed indicator (RPM)
- Fuel flow indicator
- Oil pressure and temperature indicators
- Additional instruments:
- Vertical speed indicator (VSI)
- Machmeter (aircraft speed relative to the speed of sound)
Autopilot Systems
- Automatically control the aircraft's flight trajectory using sensors and computers
- Three types of autopilot systems:
- Single-axis: controls one axis of the aircraft (e.g., altitude)
- Two-axis: controls two axes (e.g., altitude and heading)
- Three-axis: controls all three axes (pitch, roll, and yaw)
- Primary functions:
- Maintain altitude
- Hold heading
- Navigate through GPS and route following
- Autoland (automatic landing)
Cockpit Design
- Human-centered design principles ensure:
- Ergonomic comfort and accessibility
- Optimal visibility with minimal distractions
- Intuitive controls with minimal complexity
- Key components of the cockpit:
- Flight deck layout and instrument panel
- Pilot interface (displays, controls, and alerts)
- Crew resource management (CRM) principles
Flight Instruments
- Primary flight instruments:
- Measure airspeed
- Indicate altitude
- Show heading direction
- Display bank and turn rate
- Navigation instruments:
- Horizontal situation indicator (HSI)
- Navigation computer
- GPS navigation
- Engine instruments:
- Monitor engine speed (RPM)
- Measure fuel flow
- Track oil pressure and temperature
- Additional instruments:
- Measure vertical speed
- Indicate Mach number (aircraft speed relative to the speed of sound)
