....but I figured this may be a good place to start. I've noticed
recently that during take-off I feel such an immense pressure against my head and chest area that I literally can't even see straight. (its a very strange feeling of helplessness that lasts maybe 10 seconds after take off) I know it sounds crazy, but thats really the only way I can describe. I can assure you its not anxiety as I have flown literally hundreds of times from big planes to small and have been all over the world. So flying does not worry me. I also noticed that this symptom doesn't occurr at all if I sit behind the wings so Im thinking it must have to do with some sort of pressure issue. My question is, why, after 25 years, did this pressure issue become an issue now? Why is it better if I sit behind the wings? What is it? Is it a dangerous issue? Why do I seem to be the only one with this problem (I look around the cabin after I regain compsure and no one looks like they were feeling the same effects)... |

My question is, why, after 25 years, did this pressure issue become an I recall something similar once or twice over the years. Purely speculative, but I'll try....... Because you're getting older (and perhaps your body can't adapt to changes as quickly as it used to), and because the problem only seems to occur when you're in the front end of the airplane, and because it includes what you describe as a sense of helplessness, I'm guessing that what you're experiencing is the onset of mild vertigo -- spatial disorientation -- brought about by both the acceleration and the rotation of the aircraft. Once the airplane is up and climbing, and has become "relatively" stable, your problem seems to sort itself out as your brain comes to grips with this new reality. You don't know how to describe it because you have no idea what's causing it. Google "vertigo" for straight clinical information, or "aviation vertigo" for the more particular ways the term is used in regard to flying. Ask your doctor, next time you get a chance. |

Thanks for replying!
I guess I should clarify, Im not a pilot, when i speak of flying I mean on commercial jets as a customer. also, when I say Ive been flying for 25 years, I mean I am 25 years old and I've been flying my whole life. 25 yrs of age is when the body starts slowing down, not adapting as fast as it used to so I think it may be what you speculate, a vertigo issue in relation to the rapid transition (its always when the plane has taken off [never when its landing] and then specificaly starts elevating rapidly, then it stops about 10 seconds later, I suspect its because although the plane isn't done elevating, it doesn't have to elevate as quickly since its further away from the airport??). The most pressure and sensitivity I feel during these episodes is directly dead center of my forehead. Its such a bizzare feeling, you really feel like something has taken over you and there is nothing you can do, I even begin to squirm a little but it never lasts long enough to do anything substantial. I know how crazy this must all sound, but it really is true! I suspected a heart condition like you sated above but Im a healthy 25 year old, and it doesn't happen when I sit towards the back of plane and although thats not proof it isn't a cardiac issue it just seems like if it was one, it would ocurr regardless of where I sat. but I have a doctors appnt soon so I will get tested for everything (you never know). I tried googling aviation vertigo but basically nothing shows up and what does seems to referr entirely to pilots of air fighter jets.... (clearly not my demographic). Then i tried looking up vertigo itself but nothing there seems to mention planes... is there a happy medium? ![]() |

The point of the aviation vertigo references is not that the phenomenon is restricted to fighter pilots, but that they are the most obvious example of the effects. You can feel [aviation] vertigo anytime your inner ear signals do not match up with what your eyes are seeing. When your brain tries to process these conflicting signals, confusion results. If the conflict is mild, as with most people on an airplane, it is relatively easy to overcome. As you accelerate and rotate to a flying attitude, your ears sense this but your eyes see only the stationary, placid interior of the cabin. For most people, the simple knowledge that you are on an aircraft taking off is enough to allow your brain to reconcile the conflict. Perhaps you've already tried this: Next time you're tavelling, make a point of looking out of the window during take-off, so that your eyes confirm what your ears are saying to your brain.

John Gaquin You know, now that you mention it, every time this has occurred, I have been in an aisle seat not looking out, or in a window seat but it was dark out so I didn't look out the window. And almost every time I have been seated in front of the wings its because I was in first class (no, Im not wealthy, I just spend all my miles on upgrades) and seated far from the window (now that all the first class seats are fancy theyre too big to be placed right up against the window). Plus when you're behind the wings you have everything in front of you to look at passing by, but if youre in front of the wings all you basically can look at (since the cockpit obstructs your view) is the distant horizon or the sky which I guess for me may not be enough to stave off this problem. The only thing is, I do remember once a looong time ago not looking out the window when the plane took off and I dont recall this happening. Could it be a life transitional thing, meaning, something you just get simply because youre older (like some people develop allergies later in life, others lose their allergies altogether etc...)? Also, is this "illness" (or whatever its called) serious in any way? |

Vertigo can also be caused by a sudden movement of the head, such as might happen if your car were struck from behind. It can also be a reaction to long-term overindulgence in caffeine.

I'm not a doctor, nor do I pretend to have any particular insight into this
question, but I have to say I'm skeptical about all of the references to "pressure" and related physical effects. Depending on what type of aircraft you are flying in, the takeoff roll will take anywhere from 30sec to a minute, to attain a speed of 120-130Kt or so. That's a slower acceleration than your own car starting out at a red light. Atmospheric pressure differential at takeoff is about the same as going up the stairs in your own house. There may indeed be a moment of disorientation as you leave the ground, as our sneses are not "programmed" to understand this event, but the purely physical penomena at the moment of takeoff in an airliner are simply not very extreme, compared with everyday events, such as walking and driving. What do you mean when you say you "cannot see straight"? Do you see blackness? Do you see distorted images? Tunnel vision? What visual disturbances do you perceive? Do you have headaches? You complain of sinus problems - has any doctor ever suggested you may have a migrane condition? Otherwise, even though you say you are comfortable flying, one is strongly tempted to suspect this is a panic response, and the symptoms are psycho-somatic. G Faris |

Well let me clear up again that when I say "pressure" I do in fact have
no idea what Im talking about. Im not a scientist, Im not a pilot nor have I significantly studied either. So I am just saying "pressure" because I don't know what else to really call it all. To answer Marks questions, when it does happen, it happens about 1 minute after the wheels leave the ground. There is a period in flight (again, don't know what its called but I can feel it) about a minute after take off when the plane feels like its dipping down and yet flying up at the same time and its that time which causes the issue. It feel a little like a negative-G feeling. As to G's questions, when I say I can't see straight, I don't see blackness, I see the same way I see as if you've just been spun around a lot, meaning I can see everything, no bluriness, but nothing is really staying put, kind of bouncing all over the place. The same thing you'd see if you were squirming around... I have never gotten a migraine before so I doubt its a migraine issue (especially if it only comes out during the take off of a flight). I totally do not blame you for thinking its a panic response, I know anxiety (my father is a psychiatrist) and I've been aorund people with psychological disorders. I also would know when I was suffrering from one, and I too am very quick to dismiss most things as psychological, but I can assure you this particular issue isn't for me. Within 4 months of 9/11 I took 16 flights, 4 in one day alone! Im telling you, when it comes to flying, Im not anxious. Also, I am very familiar with anxiety symptoms, they are much more general, they usually start pre-boarding and last throughout the flight. Ive never heard of a panic disorder thats lasts specifically 10 seconds, nothing longer nothing shorter, and is immediately gone. No panic disorder can go away that quickly without meds. Plus, and I know this is hard to portray (nor do you have to believe me) butu when it happens, I literally feel an outside force as oppose to anxiety which is way more internal. |
