Altimeter vs. GPS Altitude in Aviation

Pilot Institute

There is also a difference between Altimeter vs. GPS altitude, and there are some important differences to cover. Altimeters measure pressure altitude above a given datum and have to be calibrated to be accurate. Key Takeaways Altimeters use air pressure and need calibration to show accurate altitude. And herein lies the rub.

Black Hawk crew may have missed key ATC instruction before Washington DC crash 

Aerotime

I want to caution that this does not mean this is what the Black Hawk crew were seeing on the barometric altimeters in the cockpit, said Homendy. The NTSB said it was confident that the radio altitude of the Black Hawk at the time of collision was 278 feet higher than the 200 feet limit for that area.

What Does A-TOMATO-FLAMES Mean?

Pilot Institute

Think about situations where equipment, like a fuel gauge or altimeter, stops working. A faulty fuel gauge could lead to running out of fuel, and a broken altimeter might leave you uncertain of your altitude. Pilot Confidence : When you know your aircraft meets the legal standards, you can fly and focus on navigating safely.

What Is Manifold Pressure?

Pilot Institute

Gauges can serve as backup altimeters in emergencies. If you fly an aircraft with normally aspirated engines, you might use your manifold pressure gauge as an altimeter. This feature makes the gauge useful as an emergency altimeter, both on the ground and in flight. Readings depend on throttle, altitude, and RPM.
