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
