Air traffic control

Since both the carrier and aircraft are moving any traffic control is much more complex and elaborate than their land based counterparts.All these operations are controlled from a command center called carrier air traffic control center This command center is situated on the top most story called is situated on the top most store called priory above the flight deck of a carrier.All aviation related data like aircraft flight plans and approaching air craft status are assembled at this center for air operations to be monitored and controlled.
For these control operations many radar systems play as crucial role outbound aircraft are allotted a 3D air corridor through which these leave without interfering with incoming aircraft incoming aircraft from various locations are first marshalled to another air corridor and speed to fly in a pattern around the csg.
Depending on the status of the aircraft whether low on fuel or hit by enemy but in a flexible conditions or having technical snag these are assigned priorities as incoming aircraft of high priority keep landing aircraft flying around the csg are instructed to move to hold pattern around the carrier as aircraft keep landing a landing sequence is formed where aircraft trail behind each other by kilometres.



Once aircraft are lined for landing these are transferred to approach and landing controlled that help the pilots in landing the aircraft during high intensity air operations aircraft come and land every 30sec for this a radar called marshalling radar is used which is the air traffic control radar.
Mars haling radar  The marshalling radar an spam 43 is a 2d surveillance a band radar dedicated for air traffic control it is used for vectoring carrier bound it is used for vectoring carrier bound air craft into final approached for landing it also acts as a back up short range air search radar for air defense operations it provides azimuth and range of detected aircraft form 80.5km to a minimum range of 229m at altitudes from radar horizon to 9144m
The radar has an inbuilt identify pries or foe system.the radar display console displays all echoes in the area of responsibly in the form of blips.But how can individual aircraft be set apart from these blips for this a system called direct altitude and identify readout is used to identify the aircraft.
DAIR. Dalr is a highly automatic beacon and radar tracking system.it is used for identifying incoming aircraft and operates as a sort of back end for marshaling operations whereas the radar operates as the front end every american combat aircraft has a transponder this transponder is queries by dare through span 4 radar.


These transponder give their identifying and altitude of the aircraft to dare through an span radar.then dare superimposes this data as alpha numerals over the blips of corresponding aircraft appearance on display consoles so mere anonymous blips are replaced but names and their altitudes this system is also capable of processing and superimposing flight plans geographic reference points and map lines for enhancing mission planning.
Marshal ling radar dare combo is a high precision system enabling controllers to track every aircraft effectiveness their consoles air traffic controlled can interact with dare for tracking a particular aircraft flight then they give in instructions for the pilot through separate communication channels that exists between air traffic controllers and pilots they line up aircraft in a ques for launching and then transfer the control to the landing and then transfer the control to the landing controllers.
In catch there are many personnel each handling a specific controlling and mini tiring task dealing with outboard aircraft incoming aircraft landing aircraft civilian and neut art flights underfunded blips and the like.
