- Describe cockpit arrangement

Detailed objectives:

1/ Generalities:
- Explain what is meant by “avionics system” and “cockpit”,
- Explain the meaning of “system”, “function”, “component”, “interface”, “HMI” and apply them to the systems addressed in this course
- Explain the role of avionics systems in Civil Air Transport
- Classify avionics systems according to their function
- Describe cockpit arrangement

2/ Basic Navigation Principles:
- Use geographic coordinates, distance measurement units, directions (heading, track) and true / magnetic referencespas
- Triangle of velocities: Describe the different speeds used for navigation
- Describe the different types of trajectories : rhumb line, great circle
- Explain dead reackoning principles
- Describe the different time references
- Explain the differences between altitude, height and flight level

3/Navigation Systems:
- Identify the airborne systems that compute aircraft position and state:
- Ground Based Radio Navigation Systems
- Satellite Based Navigation Systems
- Self-Contained Navigation Systems
- Explain the working principle of each navigation system
- Describe systems’ architecture and identify the associated main sensors
- Identify the parameters computed by each system and explain their importance

4/ Flight Management System (FMS), Flight Guidance System (FGS) and Flight Control System (FCS):
- Describe systems’ architecture and the interactions between these three systems
- Explain the differences between Electrical Flight Controls (i.e. Fly By Wire) and Mechanical Flight Controls
- Describe the main functions of the FMS: flight planning, navigations, predictions, performance optimization, trajectory computation…
- Describe the main functions of the FGS: autopilot (AP), flight director (FD) and auto-thrust (A/THR)
- Explain the principles of the flight envelope protections mechanisms
- Explain the fault tolerant design principles
