Understanding pressure altitude and GPS altitude in aviation apps

iPad Pilot News

The panel in your airplane shows indicated airspeed (IAS, derived from the pitot tube on the wing), while the iPad shows groundspeed (derived from the GPS in your ADS-B receiver or iPad). Most pilots think about pressure, since we’re constantly adjusting the altimeter setting, but even that isn’t enough to explain the difference.

The Pitot-Static System: How It Works

Pilot Institute

” The answers come from a clever little setup on your airplane: a metal tube sticking into the airstream and a tiny hole on the fuselage. It helps measure how fast the airplane is going by measuring the air pressure. The other important part of the system is a tiny hole on the side of the airplane, called a static port.

Quiz: Understanding the airplane Pitot-Static System

Flight Training Central

Airspeed and altimeter. Airspeed, altimeter, and vertical speed. If a flight is made from an area of low pressure into an area of high pressure without the altimeter setting being adjusted, the altimeter will indicate lower than the actual altitude above sea level. What altitude does the altimeter indicate?

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 the Pitot-Static System and How Does it Work?

Northstar VFR

Pilots rely on the airspeed indicator and altimeter instruments to measure and display this vital information. The static port is connected to the ASI, altimeter, and VSI. How does the pitot-static system operate the altimeter? The altimeter utilizes the static port to receive inputs of the outside static pressure.

2) Prepare the Facts Beforehand I often have my students teach me a maneuver on the ground before we get into the airplane. What does your altimeter say to start the maneuver? Say the steps out loud to yourself, move your hands like you would in the airplane. See your visual landmark in front of you.
