航空機に3軸加速度計があるとします。航空機の向きに関係なく、（地球に向かって）加速度の垂直成分が何であるかを常に知る必要があります。追加のジャイロセンサーを組み込むと、これが可能になることを私は知っています。しかし、私たちがそれを持っていないと仮定します-他の方法で垂直加速度のみを取得することは可能ですか？たぶん追加の磁力計を使用して？

I would not recommend it for an airplane and I say it is an ugly hack but you can do something with an accelerometer.
The accelerometer readings are the direct measurement of the orientation assuming that the body's acceleration in the Earth's frame of reference is negligible and the body is not rotating fast. Basically this is what you asked for, this gives you the vertical component of the acceleration (aka gravity).
This is not too useful due to the assumptions.
Magnetometers would not help, it would only help you to find where North is but it won't remove the need for the above assumptions.
There are applications where the accelerometer and magnetometer readings together are enough, without the gyros. It is the case when the body is static and the task is to measure its orientation. I have implemented such an application and worked really nicely.
