VNAV Note:
For the very moment, VNAV is still in WIP state, so it could be buggy and has some missed features and readouts.
    Known major things that could be buggy/missed for the moment:
    - Descent vnav guidance/profile could be buggy
    - No any winds is considered for vnav calculation
    - Buggy or no at all vnav guidance for holds and vector legs
    - GA in relation to vnav is buggy or doesn't work at all
