Singapore's Changi Airport ranks among the top ten in the world with the largest number of grounded aircraft, with 124 aircraft parked, according to the South China Morning Post.

SCMP, which sourced its information from aviation data company Cirium, reported that Singapore's Changi Airport was ranked ninth in the world in July, behind Hong Kong International Airport (sixth place), with 131 aircraft parked.

Hot and humid environments can cause corrosion to aircraft parts

In May, a small number of aircraft from Singapore Airlines, Scoot and SilkAir were flown to Alice Springs in Australia, a desert airport that is ideally located for storing aircraft for the long-term.

A humid environment such as Singapore is poorly suited for long-term aircraft preservation, due to the risk of corrosion to aircraft parts.

It was predicted that the planes will be out of action and remain at Alice Springs for at least three to four months.

According to FlightGlobal, as of July 3, 2020, there are a total of 22 aircraft from the SIA group parked at Alice Springs airport.

This is despite the group cutting approximately 94 per cent of passenger capacity scheduled for July.

22 parked aircraft is a relatively small number compared to the size of its actual fleet, which comprises of approximately 200 aircraft.

FlightGlobal reported that about 25 of SIA group's aircraft are deployed on passenger services, while 30 passenger aircraft have been deployed on pure cargo services.

Cathay Pacific, which operates a similar-sized fleet, plans to send a third of its aircraft, which comprises of about 60 passenger planes, to long-term storage in Alice Springs and other overseas facilities.
