Reverse-thrust is a procedure pilots use during landings to help slow aircraft down.
It requires engine power, which results in more noise. The decision to use reverse-thrust
is that of the pilot, and when used in conjunction with brakes, provides a safer way to
slow an aircraft when the runway is wet or slippery. On clear weather days, when the
runway is bare and dry, use of reverse-thrust may not be necessary. During these times,
we encourage pilots to use minimal reverse-thrust consistent with safety.

We use an automated system to monitor all landings on the north runway. Data from
this system is used to prepare performance reports on each airline. The reports are
distributed to the airlines to increase awareness of the issue. The reports have received
favourable feedback from the airlines, and members of the community have noted a
marked decrease in reverse-thrust noise.
