Why do pilots say Fox 3?

Why do pilots say Fox 3?

“Fox” calls indicate the launch of munitions from an aircraft. It’s a shorthand for Foxtrot which is often used to mean “fire”. “Fox One” indicates the launch of a semi-active radar guided missile like the AIM-7 Sparrow. “Fox Three” indicates the launch of an active radar guided missile like the AIM-120.

What physics principle underlies the fly of an airplane?

Bernoulli Principle

Where is Bernoulli’s principle used?

Bernoulli’s principle relates the pressure of a fluid to its elevation and its speed. Bernoulli’s equation can be used to approximate these parameters in water, air or any fluid that has very low viscosity.

What age do most pilots retire?

65

At what temperature do planes stop flying?

“Jet fuel begins to gel in extreme conditions and does eventually freeze, typically at minus 40 or so, although additives can be included that reduce that further,” says Haines. “Aircraft at cruising altitude will often experience temperatures of minus 50 to minus 70 F for hours on end.”

Do planes dump toilet waste?

Blue ice, in the context of aviation, is frozen sewage material that has leaked mid-flight from commercial aircraft lavatory waste systems. Airlines are not allowed to dump their waste tanks in mid-flight, and pilots have no mechanism by which to do so; however, leaks sometimes do occur. …

What does Bernoulli’s principle mean?

Definition of Bernoulli’s principle : a principle in hydrodynamics: the pressure in a stream of fluid is reduced as the speed of the flow is increased.

How cold is it at 35000 feet?

How cold is it up there? The higher you get, the colder it gets, up until 40,000 feet. If the temperature at ground level was 20C, at 40,000 feet it would be -57C. At 35,000 feet the air temperature is about -54C.

How often do planes need maintenance?

Commercial airplanes require frequent maintenance to offer a safe flying experience. They typically undergo a basic maintenance inspection once every two days, followed by a more thorough heavy maintenance inspection once every few years.

Is Bernoulli’s principle wrong?

Bernoulli’s principle is then cited to conclude that since the air moves slower along the bottom of the wing, the air pressure must be higher, pushing the wing up. However, there is no physical principle that requires equal transit time and experimental results show that this assumption is false.
