The Readout on the Radar Screen
Direct Altitude And Identity Readout is the direct display of altitude and identity on the radar screen: the information about a target, immediately visible. DAIR is the basis of air traffic control and air surveillance – the numbers that tell who flies where.
Why Readout Must Be Direct
In airspace surveillance, every second counts: the controller needs altitude and identity at a glance, without queries, without delay. The direct readout delivers both – from the transponder of the aircraft to the screen of the controller.
DAIR appears in this meaning mainly in air traffic and surveillance documentation. The abbreviation belongs to the vocabulary of the controllers – whose work depends on fast, reliable information.
