Abstract
This chapter is an applied study of the Earth’s atmosphere. This is the differentiation point between legacy maritime navigation and air navigation. The atmosphere is the framework for flight. Flight dynamics allow the calculation of the flight trajectory with respect to the air. As the atmosphere is itself on the move, for the purpose of navigation, the aerodynamic trajectory needs to be converted to the ground reference, using the wind vector field. Starting with the basic principles of atmosphere physics, this Chapter presents the flight instruments measuring air pressure and airflow direction (aerodynamic instruments).

Notes
- 1.
Meters are used instead in China, North Korea and in CIS, including Russia; the latter is in transition from meters to feet, and meters are only left below the transition flight level.
- 2.
Also 30 ft/hPa is being used for example in Numerical Close-up 3.1 but 27 ft/hPa is less inaccurate.
