How big is the g-force when a commercial airplane rises?
- John RLv 71 decade agoFavorite Answer
The largest G force you will feel will be the plane accelerating, pushing you back in your seat a bit, just as you would in a rapidly accelerating car.
The vertical G forces are not really noticeable during takeoff.

It's very small, only a fraction of 1 G. Not much different from an elevator. Commercial airliners are deliberately flown to minimize accelerations, in order to maximize passenger comfort.
For example, an aircraft that leaves the runway and achieves a rate of climb of 6000 fpm in ten seconds (which is pretty impressive for a large commercial transport) still only pulls +0.3 Gs. In constrast, a top fuel dragster will pull 6.0 Gs horizontally as it accelerates from the starting line.
If the rate of climb or descent is not changing, there are no vertical G forces (beyond the constant 1.0 G of normal gravity).

You will only experience 1g in a steady (constant rate) climb or descent.
You will experience more than 1g when the climb is initiated (rate of climb is accelerating). The amount of g-force you experience will depend on how quickly the climb is entered. The quicker the climb (more rapid acceleration) the more g's.
When initiating a descent, you will experience a negative g force again depending on the rate the descent is started the g force will vary.
On most commercial flights you will experience less than 2 g's.

On all commercial airlines no more than 1g, sometimes on takeoff, it rises to 1.5g (not any higher).
