Ground Proximity Warning System(GPWS)
Definition
A system that alerts pilots to potential controlled flight into terrain by monitoring radio altitude, barometric altitude, glideslope deviation, and aircraft configuration. EGPWS adds terrain database mapping.
Why Ground Proximity Warning System Matters for Pilots
Instrument knowledge is tested on every pilot certificate exam. Understanding how Ground Proximity Warning System works helps you interpret cockpit information correctly and recognize instrument failures before they become emergencies. This knowledge is especially critical for instrument-rated pilots flying in reduced visibility.
Exam Tip
This concept is commonly tested in instruments-related questions on FAA and EASA exams. Make sure you can explain Ground Proximity Warning System in your own words for the oral exam. Practice applying this concept to real-world scenarios, not just memorizing the definition.
