Trivia: Where would an altimeter be most helpful?
Electrician’s tool belt
Correct Answer: Airplane
So why is this answer correct? : An altimeter measures the distance of a point above sea level. This makes it a crucial device in aircrafts, letting pilots know how high up they are. Hikers and rock climbers also carry altimeters to track how high they have climbed. Most altimeters are barometric, meaning they determine altitude by measuring the air pressure.
