ref the ano 12.33.04 9in flight national, i think it really strange that the pressure for flight levels will change in 2012 to 1015mb to take into account of global warming. this is the world gone wrong
Wiley, I can't imagine it making THAT much difference... 2 mb is what, about 60 feet worth? And taking into consideration that it's generally acceptable to waver +- 300 ft from your assigned altitude. Somebody refresh me, why is that again? Something to do with allowing for 'inaccurate' autopilots, and aircraft not equipped with two autopilots or similar?
Global warming or climate change. Whatever you want to call it, the repurcussion is that the ice caps will melt and sea level will rise. Increasing the standard pressure to 1015mb will effectively make our imaginary sea level lower. Surely they should make it 1010mb. Or am I just being pedantic?

Exactly, welliewanger, which exposes this as a windup, I think.
Unless climate change is so diabolical that the current cooling is actually sucking water out of the oceans and back into the icecaps. This would have enormous consequences for all the harbors, navigable rivers, indeed all economic activity built around surface water. We need to all be driving V-8 American SUVs now! Where can I buy a carbon credit that will induce someone to build a bonfire on my behalf?
Don't you think flying would be much safer without any regulation?
I once worked out that if the purpose of every on-route Air Traffic Controller in Europe were to cause collisions rather than prevent them, they would achieve 2 per year at the traffic levels at that time.
The basis of the calculation that with the known inaccuracy of vertical and horizontal positioning at that time (1980's) each aircraft could be anywhere in quite a large block of airspace. To cause a collision, the controllor could do no more than make the two blocks of airspace collide. The probability of the two aircraft, each randomly somewhere in its airspace block, actually colliding was very small indeed.
This study sat longside the disturbing thought that all that traditional on-route ATC methods achieve is a concentration of aircraft in the airspace above a small number of points on the ground.
