How B777 is called 21st century airliner?
No they are not.They keep them ice free by utting a mineral mix on he runway....which is very mugh like salt. Once spread on the runway it lowers the temperature at which water can freeze...that is water will not freeze at 0 degree celcius and freeze at wll below that temperatue if the mineral mix is sprayed over the runway. So even at low temperature the runway is ice free.
who is first women pilot in the world?
the pilot, flight crew, bagage handlears, they all piss on the runway before they clock in for the day, the amonia and saliene in the urin acts as a cheep deicer. the only down side to the system is that the tiers tend to drip dry in flight. (ever have a plane fly over head) no body objects because nobody beleaves.Where can i find a free download of a 1958 cessna POH manual?
They don't heat them.When calling up fighter jets, what are they doing when they say they have to be "scrambled"?
The most common deicing chemical is urea which is only good down to -7C.
What makes for the time difference?
NO they aren't. They just keep plows on them to keep them clear and if it gets too bad, they cancel flights!Have you ever flown in a helicopter, when and why?
A few attempts have been made at heating airport runways but the cost of fuel to keep it sufficiently warm is prohibitive.Any recreational pilots, particularly British, please help me?
Various compounds are used to reduce the accumulation of ice on runways. The most popular is urea. It is most effective if it is spread on the runways and taxiways prior to precipitiation. Liquid anti-icing compounds are sometimes used when allowed by environmental regulations. Propolene glycol (a close relative of the anti-freeze in your car) is preferred as it is nonpoisonous and low polluting. Frequent physical cleaning -- snow plows and huge rotary brushes -- is also employed to keep runways and taxiways as clean as possible.
Does anyone know the China Air Cargo sched. for BNA on Dec 30th??
It's a common mis-conception that runways must be totally ice and snow free for safe operations. Nor is it practical to achieve that. During precipitation, runways are frequently tested and a friction coefficient is published for aircrews to use in calculating safe landing distances. If the runway is long enough, an airplane can safely land on glare ice. Temperature is a significant factor here as well. If temps are right near freezing the surface may be very slippery making aircraft operations impossible. However at very low temps -- say -30 F or below, glare ice has nearly as good a friction coefficient as bare concrete and its presense is not a significant hazard to aviation.
How many miles does an Airplane fly in one minute?
No the runways are not heated, they spread a mixture on the runway to melt the ice, very similar to what they do on the roads. You will find at sometimes that the runway is not completely ice free and the aircraft continue to operate in a safe manner.The airport crews work really hard to keep up with the winter weather, ie... most of them are out all night plowing and treating the runways so passengers don't have to be inconvenienced by bad weather.
