Interviewed on BBC News today, Emma Gilthorpe, Executive Director of Heathrow Airport, explained the need to reduce the number of aircraft using the runways by saying "we need to leave more gaps between the planes... and because we need more gaps that means we can land less planes".

Surely if there are less (she means fewer) planes that means there are fewer gaps, not more gaps...

Not just on the runways. There are prescribed distances between planes - for instance, planes following Airbus 380's need a (?) 6 minute gap before passing through the same air space. This is due to the turbulence that aircraft in weight categories produce. In cold weather, the air is denser, hence turbulence is more pronounced. In wet weather, turbulence can cause local condensation due to pressure differentials. Coupled with lower visibility both in the cockpit and by air traffic controllers looking at the air immediately around airports means greater gaps are needed to prevent that oops-crunch moment.

*** Edit: some tech-speak clarification from http://seattletimes.com/html/businesstechnology/2018240004_airbus19.html

"On approach to an airport, the required separation distances behind the A380 are 8, 7 and 6 miles, respectively, for "small" airplanes (such as business jets); "large" planes (such as a 737); and for "heavy" planes (such as the 767 or 747)."

Not really, they mean "more gap" not "more gaps". Most news now uses colloquialisms to some extent, it can hardly be a suprise.

Or indeed just poor, inaccurate and sloppy English.  Not that I'm a pedant of course!  smiley

I hate the use of the term "less" when they mean "fewer" - and "sat" when they mean "sitting"!

While I was sat sitting here, I watched the video and as far as I can tell, she really to meant to say that they need 'longer ' gaps between planes so it was as you say, sloppy English!sad

Maybe these gaps are like the holes in Yellow Submarine.
