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.

How to Read METAR and TAF Reports

Pilot Institute

Altimeter Pressure (A2990) The next part of the report indicates the local atmospheric pressure, measured in inches of mercury (inHg). Pilots use this value to adjust their altimeters, ensuring they display altitude as close to mean sea level (MSL) as possible. Its also possible to report negative temperatures with an M prefix.

The Day I Learned to Trust My Instruments

Air Facts

I focused on the panel: attitude indicator, heading indicator, altimeter. As I re-entered the clouds, turbulence increased. The turbulence wasnt extremelight to moderatebut inside that gray cocoon, time slowed. I locked into a steady scan: attitude, altimeter, turn coordinator, back to heading. Trust the tools.

There Is Definitely an Art to the Intro Flight

Flying Magazine

If you use an AATD for the first part of the experience, when you get into the actual aircraft, point out the airspeed indicator, attitude indicator, altimeter, etc. While you may be OK with marginal VFR, turbulence, and winds 10 gusting to 18, chances are pretty good the customer wont be if it is their first flight in a small airplane.

The anatomy of a commercial flight – all you ever wanted to know:   Part two   

Aerotime

While many believe that down-pull blinds are simply more susceptible to turbulence or heavy landings, making them more likely to simply drop down, there is an even more logical explanation than this. This again is a safety feature, but one which has traditionally been misinterpreted.

Who is the pilot in command of your aircraft?

Air Facts

“The instrument conditions, likely turbulence, and increased workload imposed by beginning the approach phase of the flight presented a situation that was conducive to the development of spatial disorientation and a loss of situational awareness. Then a strange thing happened.

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. Turbulent or rough-air speed. Airspeed only.
