At the moment, most aircraft taking off to the west turn south around 1.5 miles from the end of the runway which results in a steep climb to get up to altitude. This turn takes them over where we live and, because the turn is early in the flight and aircraft lose height when the turn, they have to open the throttle wider to keep climbing. This is worse in the holiday season: when the air is warmer aircraft don't climb as well as when it's colder, jet engines are less efficient and it's exactly when aircraft are more likely to be fully loaded.
We think that the Airport could use a flight path to the west that goes straight up the Tyne Valley over an unpopulated area. They could climb more gently and turn south several miles later at a height at which noise impact would be minimal. It's a slightly longer route but it would make a huge difference to us.
The Airport won't do this, they think that this will put airlines off flying services out of Newcastle. It claims that there would be an increase in fuel use and hence CO2 emissions as well as cost to airlines. We think that this might be wrong and that the difference would be small, if any: a more gentle climb would need a smaller throttle setting added to which there would be less wear and tear on engines with reduced maintenance costs
We asked the Airport to show us the evidence for their conclusion - they refused saying the report was a private internal document. We think their assertion should be exposed to scrutiny for independent validation.
