To apply for an NOC to build above the permissible height (for buildings within a 20km radius of any airport and those not in or near the approach/ takeoff path), a builder must pay an initial fee of Rs 2 lakh to AAI. If the proposal is admissible, the builder pays another Rs 22 lakh-plus for an aeronautical study. So an NOC costs around The norm is followed across India
In June 2011, the AAI began charging builders just Rs 2 lakh for an NOC for projects in the vicinity of Juhu airport. From August 2012, it discontinued charging even the Rs 2 lakh with retrospective effect from April 1, 2012. About 11 to 12 NOCs were issued every month
The upper permissible limit for buildings within a 2.5km radius of Juhu airport (and those that don’t fall in or near the aircraft approach path) is 49.87 metres above mean sea level (AMSL). From June 2011 onwards, AAI started allowing builders to go
Any builder who paid just Rs 2 lakh could build to a height of 56.27m AMSL
Last week, AAI officials, in the interest of safety, decided to review NOCs granted since June 2011. Builders plan to go to court. NOCs have been issued to over 150 projects which do not fall in the aircraft’s approach path. The limit here has been set at 49.87 metres above mean sea level (AMSL). But, citing the Negi report, the AAI started granting permission to increase the heights of buildings to above this limit. “Any builder who paid Rs 2 lakh could build up to a height of 56.27 metres AMSL. Those who did not pay Rs 2 lakh were given 49.87 metres AMSL as the upper limit,’’ Narasimhan said. AAI chairman V P Agarwal was unavailable for comment despite several attempts to reach him.
The AAI, following several protests from helicopter operators has now conceded that the Negi report is technically unsound and so the height increase permissions the authority has granted to builders could compromise flight safety at Juhu airport. “But the AAI has already granted height increase permissions to over 100 builders. Some of them have started constructing. The AAI has a tough job on its hands now,’’ said the source.
Negi had specifically said that the secondary runway at Juhu was redundant, but pilots argued that when Mumbai airport’s main runway is shut and secondary runway used, then the Juhu airport’s secondary runway has to be used as the main runway and Mumbai airport’s secondary runway have converging flight paths.
