Navigation

In the sea even gigantic carrier appear smaller then a dot for their aircraft flying at heights greater than 10 km.At those heights visually sighting the carrier becomes impossible.To retrieve the launched aircraft the carrier must reveal its postulation to the  its posturing to the incoming aircraft.The carrier does nit this through a system called Tactical air navigation.

Chant through a ta can transponder the carrier continuously relays its identify mi mores code at a particular frequency.Through appropriate antenna arrangement it maintains a carotid radiation pattern for this transmission.Aircraft can revolve these signals by tuning their Tara receivers.

These receivers compare aircraft bearing with the direction of the signal reception and give the bearing of the carrier to the pilot.The ta can receiver also gives the slant range,known as crow flight distance of the carrier.

For this aircraft ta can receiver interrogates the carrier ta can transponder with the carrier interrogate pulse.The tactician transponder receives that and after a delay of 50 sends a reply signal aircraft ta can receiver receives this replay.Then by knowing the time at which the receiver had sent the interrogating pulse and the time it receives the replay it calculated the round trio distance time this time minus the 50 delay is the actual round trip distance time with the speed of the radio waves known range is calculated which is the crow flight distance.

Typically a ta can transponder of a carrier can provides navigational data to approximately 100 craft simultaneously interrogating at a time.With ta can an aircraft can accurately navigate to the carrier diction and range are displayed in aircraft moving map display as way points and also as pointers in the pilots head up display .

The next task is to control the movements of outboard and in bounded aircraft.Appropriate commands and support are given to inbound air craft for landing this is done by carrier air traffic control which is generally called amphibious air traffic control.
