A standard runway is given a quantity denoting its energy however issues are performed otherwise when the runway is made from ice.
Crews use what is named a proof curler, weighing 88 tonnes, to roll excessive of the runway and establish pockets the place the ice is weaker. These holes are then stuffed in and retested.
Proof rolling takes about 22 hours and is completed constantly, up and down the runway, altering drivers when required.
“You must ‘proof’ that the runway can face up to a sure drive, and that drive is larger than the drive the plane will place on it,” Mr Learn mentioned.
“This yr we had 405 failures so we needed to restore 405 areas, taking about two very laborious days to restore.”
Lastly, within the days earlier than the primary flight arrives, employees run a tiller up and down the runway to supply ice shavings, which then freeze and create sufficient traction for the airplane’s wheels.
The wind pace needs to be below 20 knots although, or the shavings fly away.
