What is the Standard Pressure Region?

Attitudes and Movements

The standard pressure region is airspace that includes the Northern Domestic Airspace and all airspace above 18,000ft within the Southern Domestic Airspace. When flying in the Standard Pressure Region, your altimeter is set to 29.92 in Hg and all altitudes are expressed as “flight levels.”

For example:
FL210 = 21,000 ft
FL90 = 9,000ft

To maintain vertical separation between aircraft flying high in the Altimeter Setting Region of the Southern Domestic Airspace and the Standard Pressure Region, there are lowest useable flight levels for lower than normal pressure measurements.
If the altimeter setting is 29.92 in Hg or higher, the lowest usable flight level is FL180
For 28.92 to 29.91 in Hg, it’s FL190.
And for 2792-28.91 in Hg, it’s FL200.

OBJECTIVE

To understand the range of attitudes through which the aircraft is normally be operated.
To understand how the various attitude necessary for flight are produced and controlled.
To understand yaw and how it is controlled.

MOTIVATION TO LEARN THESE ATTITUDE AND MOVEMENTS

Understanding the different attitudes and movements and how they are controlled are fundamental to learning to fly an airplane. Without proper knowledge of which controls are used to make changes to your airplanes orientation you will not be able to perform the necessary air exercises to prepare you for your flight test.
