Definition
Portable, battery-powered GPS receivers that a pilot can carry into the cockpit and use as a supplemental source of position, ground speed, track, and basic navigation information. They are not installed in the aircraft, are not wired into its avionics, and are not certified for use as the primary means of IFR navigation. Their use is limited to situational awareness and VFR navigation unless the unit and installation meet specific certification standards, which hand-held units generally do not.
Plain English
A small, portable GPS unit you can bring into the cockpit. It helps you see where you are and where you're going, but it isn't an official part of the aircraft and can't legally replace the approved navigation equipment for instrument flying.
Context Anchor
Seen in discussions of GPS equipment, especially when comparing portable GPS units with panel-mounted GPS equipment installed in the aircraft.
Derivation
“Hand-held” means small enough to be held and operated in the hand. GPS stands for “Global Positioning System,” a satellite-based system that helps determine position anywhere on Earth. Together, the term points to a portable device that uses satellites to show location.
Why Pilots Care
Provides critical redundancy so a pilot can continue safe navigation during instrument flight if the aircraft's primary electrical or GPS systems fail.
Intuition Check
Do not assume “hand-held GPS” means “approved aircraft navigation system.” It may give useful position information, but approval depends on how the equipment is installed, certified, and authorized for the flight.
Example Sentence 1
She carried a hand-held GPS as a backup, but flew the approach using the aircraft's certified panel-mounted receiver.
Example Sentence 2
Before an IFR cross-country, the student verified the hand-held GPS system battery was fully charged as a required backup.
