Don’t count on quieter jets

Re: “Upgrade could cut volume at airport,” April 22.

The Calgary Airport Authority is misleading us in saying the Required Navigation Performance (RNP) procedures “may” reduce noise. RNP was designed to reduce flight times and fuel costs for the airlines.

The noise issues many Calgary neighbourhoods are experiencing are caused by high-density air traffic corridors.

When there are 100 to 150 jets and helicopters over one’s neighbourhood every day, the noise reduction by a few planes using RNP will be negligible.

Instead, YYC must widen, relocate and alternate corridors to give those of us on the ground a break. Jane Hillard, Calgary
