Datalink

INTRODUCTION

1.   General.   A datalink is a means of transmitting information from one point to another. When the transmission is accomplished using a wireless means, the datalink may also be referred to as a 'radio link' or 'radio modem'.

INS
INTRODUCTION
 
1.   The navigation function forms part of the Guidance, Navigation and Control (GNC) system and consists of calculating a platform's location and velocity (also known as the state vector), as well as its orientation (or attitude). Navigation relies on input from a variety of sensors and subsystems.

INTRODUCTION

1.   Air data information is a key issue for use onboard aircraft in order to estimate current altitude and airspeed. Such flight parameters may be measured using a variety of different sensors.

In the very early stages of aviation, control of an aircraft was based purely on visual feedback and sensorial perception: flying ‘by the seat of the pants’. Such instruments as were available in the cockpit were very basic and limited in their capacity. As aircraft complexity has increased, more information and more complex instruments have become available.

Radar Altimeter

INTRODUCTION

Altimeters are devices designed to calculate the height of an aircraft above the surface directly below it. This height may be Above Ground Level (AGL) or Above Sea Level (ASL).

Different types of altimeter use different technologies to calculate this height, including pressure-density to altitude relationship and the propagation and reflection of electromagnetic waves etc.

GNSS

Navigation is a process involving three steps:

  1. Establish the track that needs to be followed (i.e. Flight Plan)
  2. Establish current position relative to the FP
  3. Execute all necessary guidance actions to correct any deviation in position

There are different types of navigation system:
