Altimeter Setting

Question 1

Altimeter setting region

Answer 1

All low-level airspace in the SDA

Aircraft must set their altimeter to the altimeter setting of the station nearest to the aircraft

Question 2

Standard pressure region

Answer 2

All high-level airspace plus low-level airspace in the NDA

Aircraft altimeter must be set to standard pressure of 29.92 inches of mercury/ 1013.2 hectopascals

in this region Flight level is used instead of altitude

Question 3

Passing from altimeter setting region to standard pressure region in level cruise

Answer 3

Pilot will set altimeter to 29.92 inches of mercury immediately after leaving the altimeter setting region

Question 4

Passing from standard pressure region into altimeter setting region in level cruise

Answer 4

Pilot will obtain the current altimeter setting from the nearest station along the flight route and will set the altimeter immediately prior to entering the altimeter setting region

Question 5

Climbing from altimeter setting region to standard pressure region

Answer 5

Pilot will set altimeter to 29.92 inches of mercury immediately after leaving the altimeter setting region

Question 6

Descending from the standard pressure region into the altimeter setting region

Answer 6

Pilot will obtain the current altimeter setting from the nearest station along the flight route and will set the altimeter immediately prior to entering the altimeter setting region
