Some of you may have heard that airliners headed to Calgary International are going to be changing their landing patterns. Known as Performance Based Navigation (PBN) in the United States, what is called the Required Navigational Performance Procedure (RNP) in Canada will eventually be deployed throughout North America. While the details of the flight patterns, both current and anticipated are complex, there are some basic points we are excited about:
There will generally be less noise
The current landing patterns require the planes to descend in steps. This forces planes to fly closer to the ground earlier in the landing pattern, and requires planes to fire up their engines repeatedly through the process. The new system allows planes to stay higher in the air until they have lined up with the runway. In this system, planes will lose altitude at a greater angle as they finish their approach, without the need to fire their engines. If you do not hear the planes now, you will likely not notice a difference in the future.
There will generally be fewer greenhouse gases, and pollutants over Calgary
Because of the decreased fuel use and shorter approach times, planes that use this approach will see a decrease in emissions. Calgary International Airport already hosts some of the newest fleets in North America. Our airport does not generally see planes with older emission technology. This landing pattern innovation will make a good situation even better.
Please keep in mind these changes won’t be immediate. Because the RNP procedures require special navigational equipment onboard the airplane and pilot certification to make use of the equipment, not all flights will employ RNP immediately. West Jet is already set up to do so, but the other airlines will adopt this procedure as they acquire the necessary resources.
Please join Nav Canada and the Ward 11 office at the Palliser Bayview Pumphill Community Association on January 6, 2016, from 6:30 to 9:00 pm to view the diagrams available and ask any further questions you may have.
Members of the public are also invited to provide input into the discussion of the airspace
changes via an online survey by January 30, 2016.
