What actually happens when fighter pilots take off their masks

  • A fighter fly’s mask is primarily used to prevent the pilot from getting hypoxic, which is the lack of oxygen to the brain.
  • The make happen of flying without the mask depend on how high the jet is flying and how long the pilot goes without the mask.

What happens if a fighter pilot takes off their mask? Movies equivalent to “Independence Day” and “Top Gun” portray it as a final act of desperation that’s strictly against regulation. But is this true? Before we get to the answer, let’s initial look at the purpose of the mask.

A fighter pilot’s mask is primarily used to prevent the pilot from getting hypoxic, which is the be deficient in of oxygen to the brain.

As part of our training, we’ll go into an altitude chamber where the atmosphere is reduced to one-third of what it is at sea pull down. The purpose of the training is to recognize our symptoms so that we can take emergency action should we experience it while flying.

For most people, their tokens start off as tingling in their fingers, followed by light-headedness and mild euphoria. Left unchecked, this can quickly about to confusion and eventually to losing consciousness, which can be catastrophic in a single seat aircraft. Modern masks also induce several additional features to aid the pilot.

Nearly all masks have a microphone built into them. By shoulder a button, usually on the throttle, the pilot can communicate across one of the several radios onboard the aircraft.

Some also be struck by a light built into them. Typically, at night we’ll fly with the cockpit as dark as possible, however, when understanding a map or writing, we’ll push a button inside the mask with our tongue, activating the light for a short amount of time. The most urgent innovation though has been the ability to smartly regulate the pressure inside the mask.

As altitude increases, breathing matures more difficult because the pressure inside your lungs no longer has a large differential to the air pressure outside your hull.

By introducing positive-pressure and forcing air into the pilot’s lungs, this effect can be countered, reducing fatigue on the pilot. Imperious pressure also helps us to counter the G-Force we experience during heavy maneuvering.

I weight 210 pounds, 240 with my outfit on. If you’ve ever been on a roller coaster that does a loop and pushes your head down, that’s encircling 3G’s. In a modern fighter, we’ll pull 9Gs. That’s over 2,000 pounds of force crushing me into my seat. It feels partiality a car is parked on your chest. This can make it extremely difficult to breathe. By forcing air into the pilot’s lungs, chic masks help us breathe under high G for sustained amounts of time.

Now that we’ve gone over what the mask does, let’s talk yon the air pressure inside the cockpit. Fighter aircraft are different than civilian airliners: In order to save weight and space, we don’t preserve constant pressure inside the cockpit.

From sea-level to 8,000 feet, we don’t pressurize it at all — it’s the same as if a hole was cut in the canopy. From 8,000 feet to wide 25,000 feet, we maintain 8,000 feet inside the cockpit—similar to many ski resorts. Once we climb beyond 25,000 feet the cockpit altitude slowly rises so that by the time we’re at 50,000 feet, the pressure inside the cockpit is comparable to about 20,000 feet, or the altitude of some of the tallest mountains in the world. (Everest is 29,000.)

So, what happens if a pilot mulcts off their mask? The answer is it depends. If they are cruising under 25,000 feet, they can fly for a long period of epoch with their mask down and not feel any effects. We don’t though because a cockpit depressurization could rapidly suck out the air — much stabler than an airliner due to how small our cockpit is.

Additionally — as anyone who’s visited a high city can attest — it’s easier for fatigue to set in. Chiefly 25,000, though, extended time without a mask will eventually cause hypoxia.

Because dehydration can be equally hurtful as hypoxia in a fighter, most pilots will drop their mask several times throughout a flight to slug water, and for longer missions, to eat. As long as it’s just for a short time, the effects are negligible and actually encouraged by our aerospace physiologists.
