Transition Altitude
Definition
The altitude at which pilots change from QNH altimeter setting to standard pressure setting (29.92 inHg / 1013.25 hPa). In the US it is 18000 feet. Below this altitude, local QNH is used.
Why Transition Altitude Matters for Pilots
Navigation concepts like Transition Altitude are tested on instrument rating exams and are essential for safe cross-country flying. Whether you are planning a VFR flight or navigating under IFR, a solid understanding of Transition Altitude ensures you can find your way accurately and efficiently.
Exam Tip
This concept is commonly tested in navigation-related questions on FAA and EASA exams. Make sure you can explain Transition Altitude in your own words for the oral exam. Practice applying this concept to real-world scenarios, not just memorizing the definition.
