Muscat: Oman's Public Authority of Civil Aviation (PACA) has implemented low noise operating procedures at Muscat International Airport to minimise noise over sensitive and populated areas near take-off and landing paths.
H.E. Dr. Mohammed Bin Nasser Al Zaabi, Chief Executive Officer of PACA said: "The application of reduced noise operational procedures at Muscat International Airport is one of the most important long-term solutions to address noise, and a very important and advanced step in the civil aviation sector in the Sultanate — and to contribute to the protection of the environment from noise pollution."
The new reduced operating procedures for noise at Muscat International Airport are threefold: takeoff procedures, procedures for approaching and landing aircraft from Muscat International Airport, and noise control procedures from the engine test on the airport floor.
The first procedure involves requiring all types of aircraft to follow routes such that the aircraft reaches a height of 3,000 feet above the airport as soon as possible after take-off and then adjust turbines to reduce noise from their engines, without compromising the safety of flight operations.
The second type is the approach for landing aircraft at Muscat International Airport, which has been designed to reduce the noise caused by the movement of aircraft coming to Muscat airport following what is specified in the Flight Operations Manual.
Al Zaabi says: "This type of procedure includes requiring pilots who apply visual landing procedures to continue to fly in the appropriate direction to the runway at a height of at least 1,500 feet until the final stage of approaching the runway is reached. Pilots that need to land at night [are directed not] to use reversing or reverse-thrust devices that result in high noise, except for technical or safety reasons."
The third procedure is the noise control parameters of aeronautical tests, that prohibit engine testing in non-designated areas. These procedures also include the allocation of a specific location to operate the engines for testing within a time period not exceeding 5 minutes, or greater than those used in normal conditions of operation and traffic at Muscat airport. Approval of the air control tower is also required to move the aircraft to sites dedicated to the tests.
