A Beechcraft B350 aircraft from the Airports Authority of India (AAI) landed in Kannur International Airport at 4:35PM on 30.08.2018 for the calibration of the Instrument Landing System (ILS).
The calibration was carried out from 31.08.2018 – 01.09.2018. The activity was done by a Flight Inspection Unit (FIU) from AAI led by Mr L.N. Prasad, AGM (FIU).
The calibration aircraft was piloted by Captain Sanjeev Kashyap and co-pilot Dikshit
ILS guides aircraft to land safely even under poor weather/visibility conditions. It consists of a localiser, glide path and distance measuring equipment. Localiser gives the lateral centre line of the runway and glide path gives the glide angle.
Each of these equipment was independently checked with systems on-board the aircraft. The required adjustments were done by the ground team comprising Communication Navigation and Surveillance (CNS) members. It was rechecked and found to be fit for operation.
While ground measurements can be done, flight inspection is critical due to the influence of terrain, atmospheric factors, etc.
Since this is the first (commissioning) inspection, more number of exercises were carried out in the flight inspection, to bring all parameters to ideal value.
The aircraft departed at 11:30AM on 01.09.2018 from Kannur International Airport, after the calibration was completed.
The FIU team from AAI will be submitting a detailed report to the Directorate General of Civil Aviation (DGCA).
A commissioning instruction would then be issued. Also, the ATC will be formulating procedures for landing of aircraft. Once both of these are ready, the ILS can be used.
The calibration of ILS is valid for a period of six months.
