Civil air navigation system operator Nav Canada intends to launch new landing procedure for planes at the Calgary International Airport in Alberta which can reduce flight timings and result in fuel savings.

Termed as the ‘Required Navigation Performance Procedure’ (RNP), the process will involve implementation of advanced GPS technology to make entry for the airplanes into the airport much smoother.

Each flight descents supported by RNP is expected to result in three to four minutes of flying time savings and up to 200l of fuel savings, Nav Canada said.

"The RNPs that Nav Canada are proposing are actually already being flown now."

The landing procedure is also expected to reduce air traffic noise around the Canadian city.

Calgary Airport Authority spokesperson Jody Moseley was quoted by CBC News as saying: "The RNPs that Nav Canada are proposing are actually already being flown now.

"So it’s a matter of a little bit more precise flight path. We think that there’s a benefit because that aircraft comes in quieter and also gets in quicker and those are really important things for the community below."

Nav Canada Government and Public Affairs director Michelle Bishop said: "There are obviously fuel savings with reducing that number of track miles as well and when aircraft reduce their fuel burn, we reduce the amount of emissions that we’re emitting into the environment."

Initially, about 10-25% of aircraft are expected to use the system.
