Well -that's how a computer game designer would think maybe

For a starter - even if it was a good idea, how would you calculate a "vertical angle of heading"? How about AOA (angle of attack) for example? And if you could get the real "vertical angle of heading" - it would have to no use as the aircraft "longitudinal angle" would only be related the air that surrounds the aircraft... And what if that air is moving up or down (which is the thing that happens up there IRL accept a dead calm winter day)? What good would then the fact that the aircraft "moves at an angle of 2 degrees at 200 Mph" do you if the air surrounding the aircraft moves down at 8 m/s? What is the real rate of climb (or descent) then?

Do some reading on variometers as there are a lot of parameters to consider accept the 1940 versions that actually only worked on atmospheric pressure rise/drop that gave many problems...

Start here for example:

EDIT: And no - if you climb through non-turbulent air they don't oscillate (accept for engine vibrations )... In turbulent air the problem is mostly that they oscillate to little compared to reality
