Surat: The Airports Authority of India (AAI) has invited tenders for the strengthening the Surat airport runway strip for reducing damage to the aircraft in the event of an unintentional excursion from runway surface, as per the International Civil Aviation Organisation (ICAO) standards.
The project, which was to be taken up during the runway expansion of 655 metres in 2016-17, has been delayed by five years.
A runway strip—and its graded portion—aims to reduce the risk of damage to aircraft running off the runway and to protect the aircraft flying over it during take-off or landing operations.
Aircraft manufacturers consider a depth of 15cm below the finished strip surface be prepared to have a bearing strength of California Bearing Ratio (CBR) of 15. The intention of this underlying the prepared surface is to prevent the nose gear of the aircraft from sinking more than 15cm in the event of excursion and veering off from the main runway.
A senior AAI officer seeking anonymity said, “The input cost for the strengthening of the runway strip at Surat will be increased by 30% as the prices of cement and steel have increased compared to 2017. However, the runway strip work is the need of the hour to protect the aircraft in the event of excursion from the main runway.”
