Why does that happen? How come it doesen't happen always? Is it bad for a persons health?

If you know the answer please reply.

it is caused by the change is pressure. try chewing some gum during landing. it used to happen to me until i had ear surgury, i now have small holes in my eardrums. so the pressure inside my ear is the same as in the cabin(if my ears are clean   )

Perfectly normal to have a feeling of fullness, even of slight pain, from the pressure changes. This can happen on takeoff and landing, as well as steep banks or rapid ascent/descent in-flight. You know you have a problem if the feeling doesn't go away within five to ten minutes, or if it spreads to your sinuses, or you get a runny nose. In that case, you're probably getting a cold!


Up, up and away!

Why does it only happen some times?

This kind of feeling in your ears is indeed caused by the air pressure rising in the cabin as the plane drops to a lower altitude. Chewing gum is okay, but it doesn't work that well me personally. What I do is simply either yawn(only if I'm tired) or hold my nose in the same way that I would respond to a very bad smell, and try to exhale through my nasal cavity until the eardrums pop and the hearing goes back to normal. I don't get that kind of feeling in my ears that often, as I wear hearing aids.

Changing air pressure will not cause any health problems, although it may hurt a little bit in some people, but if there is serious pain associated with it, it could mean an ear infection. This kind of pain is not uncommon in children and babies while airborne. Their internal ear structures are not only more fragile, but they're more sensitive than those of adults. A lot of times when I'm flying, especially in a jet a/c, I often hear at least one or two kids crying and complaining that their ears hurt.

As for why it doesn't always happen, the cabin may be so well pressurized, that you won't notice, or that the plane didn't fly at that high an altitude to cause greater pressure differences. Sometimes the plane may descend so gradually that your ears adapt better.

That's your brain trying to squish it's way through your ears.

...the actual landing itself, and not the descent from altitude, it's probably the aircraft depressurizing.

Every transport I know of has a "squat" switch of some type or another that is closed when the weight of aircraft settles on the main gear struts. Think of the main gear struts as big shock absorbers with an electrical switch on the top/bottom halves that connects when it's compressed.

The reason for this system (some call it an air/ground sensor, or other names) is so that the aircraft "knows" absolutely positively when it's on the grouind, and when it's in the air. Why? There are some aircraft systems you want to work *only* when on the ground and *never* while you're in the air, and vice versa. Examples are thrust reversers, ground spoilers (only on the ground, never in the air), and on the flip side, landing gear (always in the air, never on the ground).

Another thing tied to the system is the pressuration system's outflow valve, which opens onces you're on the ground, allowing the cabin pressure to match the outside airport pressure. If this didn't occur (automatically, to avoid "human error") and the aircraft bellied in with fuselage intact, nobody onboard could escape (a possible fire?) since the still-pressurized cabin would be pressing down on the plug-type entry doors, preventing them from opening. A bunch of folks on a Saudi L-1011 met their doom this way after a successful emergency landing years ago. Nobody could evacuate since the cabin was still pressurized, and everyone burned with the aircraft.

The 727 has no such outflow ystem. The plane is intentionally pressurized on the ground to a max of .125 psi. Standard 727 operating procedure.

In a change of altitude, the air pressure changes. Therefore, the air pressure of your inner ear wants to become in equilibrium with the current outside air pressure.

In landing, the air pressure in your ear is lower than that outside, therefore, it feels like it is contracting. To remedy this, hold your nose and mouth shout, and try to breath out, this will force air up the inner tracts in your head and add more air to yours ear, bringing them to air pressure equilibrium.

For take off, it is the opposite.

So why do pilots sometimes land with a steeper glideslope? That is what I thought, also, is the cause of your ears feeling different upon landing on different flights. For example, once I could just feel the pressure in my ears while other times my ears were in a lot of pain (so much that I sometimes sweat). Shouldn't they all start descent at the same angle when they fly into different airports?

727's don't have outflow valves? Wow! I must have been changing the wrong parts then.....


This plane is built to withstand anything... except a bad pilot.

Maybe I could have explained it better. As we all know the 727 has an outflow valve. Even people who never changed one before could probably figure that out.

The 727's pressurization system has no link to the air/ground sensing. The 727 is pressurized on the ground to a max differential of .125. If an emergency evac is necessary the cabin outflow valve must be opened.

holding your nose and closing your mouth while trying to exhale is known as the valsalva maneuver. (or "equalizing" if you're a diver...)

like samurai said, it is much worse when you have sinus congestion because it may be much more difficult or even impossible to equalize the pressures...

Not to arbitarily quibble with someone who actually flies the aircraft, but re: your statement that "The 727's pressurization system has no link to the air/ground sensing", how is it that a failure of the air/ground sensor (aircraft stuck in "ground" mode after takeoff) results in the inability to pressurize the cabin, in addition to not being able to raise the gear? Having I been been dreaming the various times this has happened in my career?

DLmech, interested in your take on this too, as if anyone has the schematics, it's you...

About one year ago I was unable to equalize the pressure in my years. It took them something like three days to open up and I've had an annoying ringing sound in my right ear since then.

I know this is extreme, but it's still worth being careful...
