The US Federal Aviation Administration (FAA) has granted a request by trade group Airlines for America (A4A) waiving slot usage requirements at Newark Liberty International airport during runway work scheduled for later this year.
The group representing US carriers asked for the waiver of rule dictating that slots at Newark must be used 80% of the time in light of planned runway construction and resurfacing of 4R-22L scheduled between 15 April and 15 December of 2012.
During that time nightly and weekend closures of the runway are planned as well as closing of the intersection of 4R-22L and runway 11-20, which will result in the shortening the available length of both runways, said A4A.
The group argued the closure would significantly impact Newark's throughput since 4R-22L is the airport's principal arrival runway.
FAA granted the request with certain conditions. The waiver only applies to slots on Saturdays and Sundays from 15 April through 15 November, from 4 May through 9 May during the intersection closure and from 8 September through 17 September.
To obtain a waiver carriers must temporarily return slots they will not operate during the waiver period. FAA stated a carrier would retain historical precedence for the temporarily returned slots.
The deadline for temporary slot returns for the summer timetable is 16 March and for the winter 2012-2014 timeframe 15 August.
