Airport Authority of India has introduced the concept of the Height Clearance NOC and all the applications are managed by the NOCAS. The list of calculations includes the permissible height and the elevation point, according to the Site location coordinates, plus the installations like radios/TV aerial/vent pipes and relevant attachment. The legal height clearances are assured by the Designated Officer altogether with the inputs of the Aeronautical Ground Aids (AGA), Surfaces or Obstacle Limitation Surfaces (OLS), Communication Navigation and Surveillance (CNS). GRP Estate delivers the effective consultancy services for the Height Clearance NOC. Looking for assistance? If yes, then request a callback at 887-267-1234.
