Hobbs Meter
Definition
A flight time recording device measuring elapsed time from engine start or weight-on-wheels. Used for maintenance tracking, rental billing, and flight time logging. Different from tach time.
Why Hobbs Meter Matters for Pilots
Instrument knowledge is tested on every pilot certificate exam. Understanding how Hobbs Meter 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 Hobbs Meter in your own words for the oral exam. Practice applying this concept to real-world scenarios, not just memorizing the definition.
