Which term best describes the region where you set 29.92 as the altimeter setting?

• A. Altimeter setting region
• B. Standard pressure region
• C. Transition region
• D. ADIZ

Answer: (B)

29.92 is the standard pressure setting used for flight levels in the standard atmosphere. The region where you set this value is the standard pressure region, typically above the transition altitude. In this area, pilots set their altimeters to 29.92 so the readings reflect flight levels (like FL180) rather than true altitude, providing consistent vertical separation regardless of local pressure changes. Below the transition altitude, the local pressure (QNH) is used to show altitude above mean sea level. The other terms don’t fit because ADIZ is about identification zones, and the transition altitude is the height where you switch to the standard setting, not a regional designation for using 29.92.
