Has Anyone Ever Experienced Negative G's On Plane

Sun Jul 11, 1999 7:06 am

Negative G's, in an informal definition, is the feeling you get when you are going down a drop on a roller coaster. Also associated w/ negative G's is when a person is lifting off a seat.

For some odd reason, on every 737-300 flight when landing I get a mild negative G feeling and I somewhat lift off my seat.

Please post your experience about negative G's on airplanes.

P.S. I was away on personal matter. I have alot to catch up on reading messages!

The reason for you to have a "mild negative G feeling" when landing is because the aircraft is in a decent. You are not really experiencing negative Gs, just less than 1G... sort of like when you get on an elevator going down, you still only experience positive Gs, but they are less than 1. If you have no restraint, you will never feel negative Gs, because when you go through the 0G mark, you will enter free fall and the object that was previously supporting you will drop away. I would guess that most airline passengers only experience negative Gs when in turbulence, if you seat belt is on, or your restraint in the aircraft is the ceiling ;-) I personally love them!

btw, welcome back, I hope everything is ok

In 1986 i flew from Vancouver to LA on Canadian Pacific...It's quite something to hit an air pocket in a DC-10-10 during meal service, though it was quite mild for an airpocket. Thankfully no one was hurt

Yes, it happened while I was washing my hands in the lavatory. United 727 bound for ORD from MSY.
The plane dropped quickly and I probaly lifted about an inch or two off the ground for a second. The bathroom shakes like crazy on a plane.

I've experienced them many times... mainly in smaller jets like the CRJ and in almost all bizjets.

A few times on QX routes, once notably in a Fokker-28 coming over the Rockies! Wow, that was turbulence. Also an intance in a Dash-8, sudden sharp descent then steep climb again, may have been a TCAS advisory.

Hehehe..
I was in the bathroom of a TWA 727 in 1996 going to FLL. I was standing up, doing my business, when suddenly, we dropped about 50 feet. I hit my head on the bathroom ceiling. A woman in coach threw her coffee halfway across the cabin, burning a man.
The Delta 1011 in front of us was hit by the same thing.

Hehe...every flight i am on i experiance what FEEL like negative g's....

One flight I was in a Continental 737-500 from IAH on my way to SNA...The whole flight was very turbulent. After we took of we dropped a good distance and then continued on a right turn. I was in First Class along with some other guy in a suit so i dont know if anyone threw their coffie lol. Later that flight I was finishing up the best sandwhich I have ever had and we hit some turbulence. I felt the plane go down and me go up. My water almost tipped over. The last occurance of this was when I was playing poker with a FA. We were somewhere of NM or AZ (some desert) and the plane dropped a distance....our cards raised up all together (syncronized) and at the same hieght from the table. The cards then fell back all in place on the table.

Neg G's

It is a pretty standard instructor trick to place a pen on the glaresheild and then pitch over rapidly. This will cause the pen (and anything else in the airplane not straped down) to float in the air if it is done right. This usually really impresses those that don't know about flying.

It is about the same manuver that both NASA and ESA use in their astronaut training program to simulate weightlessness. Just it is more of a prabola(spl?) flight track with the KC-135 and A-300 used by NASA and ESA. They just have a little more power and can stay in the pitchover longer.

I was coming down to MIA from JFK on a LanChile 767-300ER back when they connected throuh MIA. We hit two airpockets. Once over Nantucket, and the other time around JAX. It was an interesting experience. Since the food had been already picked up there was no major debree. The second time I was not strapped in, so I wet up to the ceilling (sp?) and landed on my girlfriend lap. So I stayed there for the rest of the flight until the decent. It was fun and I would love to do it again.

Yes, this scares! In January 99 I was coming from Lisbon to São Paulo, and some 4 hours before landing, while crossing the Equator, still over the Atlantic, the TAP A340-300 CS-TOD came down really carelly!
Then, I notice three followed cockpit-cabin sound signals for three times (a "tam-tam-tam" x3) , such thing I'd never heard before, and crew member going to the galleys (or cockpit?). The signals and the F/A movement were really strange! I think we crossed four airpokets in some two minutes. And, I also noticed than the plane, after each altitude loss, tried to climb again, which also scared me once it seemed that the current altitude wasn't safe.
There weren't major panic or injureds because it was 3am inside the plane, 2am in São Paulo' and 6am in Lisbon' time, the movie (Truman's Show by the way) had already finished and almost everybody was sleeping.

TP343, São Paulo, Brazil.

Wow, sounds like you had a good time TP343, the plane trying to climb again after the drop in altitude is the autopilot compensating and trying to return to selected altitude, so that's completely normal, scary at times to some, but normal. Not sure what the tam-tam-tam thing is though! I think, and I'm not sure that three cockpit to cabin chimes signals the FA's of an emergency or to return to their seats, not positive though, were the tams kind of chimes? Well, gotta run!

Quite a few summer back, my dad and I were flying from Wausau Wisconsin (CWA) to ORD on an American Eagle Shorts 360. The flight was smooth until the descent into ORD, there we puffy popcorn clouds in the area, we went through one and then as we came out, I don't know how many feet we dropped, but let me tell ya, we DROPPED, felt wierd, everyone let out a big sigh! It was like a roller coaster.
