Other errors of omission: failure to fully utilize the calculation and database features of the GPS, including winds aloft, true airspeed calculations and runway information for the destination airport.

As another instructor put it to me, you can tell the GPS checkout is complete when the pilot can use it and still scan outside for traffic.Ĭruise: Zitts “biggest GPS peeve” is pilots who dont know how to activate legs of a flight plan, or to change a flight plan to continue precise, safe and legal flight as the route changes. Takeoff and climb: Aside from scrambling to input departure fixes or procedures, the biggest problem during takeoff and climb is fixation on the moving map. Before and during taxi they fail to access frequencies and runway data from the GPS database many dont use taxi diagrams or other situational awareness tools.

Taxi: Pilots rarely use the GPS features to their advantage, according to Zitt. This greatly increases workload right after takeoff, when the pilot must either enter the data in the air or devise some work-around that negates the safety and capability of the GPS navigator. In many cases the pilot knows (or can reasonably expect) hell/shell be cleared to a specific fix or along a STAR, but very often he/she doesnt load in the data. Preflight: The most common GPS error before flight is failure to use the entirety of the flight plan page. Beyond this fixation, Zitt sees these typical mistakes in various phases of flight: Prime among them is “instrument fixation” during the transition to TAA flight, a focused stare and excessive concentration on which button to push when the pilot is not completely familiar with the GPS used. Zitt notes that “each unit has its own pitfalls,” but finds common pilot mistakes regardless of the type of GPS installed.

He and his instructor staff work exclusively in GPS-equipped airplanes, some with full “glass cockpit” panels but most conventional round-gauge airplanes meeting the definition of Technologically Advanced Aircraft (TAA) through the installation of moving-map GPS. What are these common GPS errors? Whatĭavid Zitt is the Flight School Manager of Sportys Academy, the flight instruction arm of Sportys Pilot Shop in Batavia, Ohio.

Its a little surprising, then, that pilots seem to make the same errors and omissions pretty much regardless of the unit involved.

There are very different operating interfaces with units from competing manufacturers. The capability of GPS comes with great complexity. Its the rare IFR airplane that isnt equipped with at least a portable, moving-map GPS theres not an IFR-certified airplane in production that doesnt include a GPS-driven “glass cockpit” as at least an option-one thats almost always added. Theres no question ours is an era of great advances in safety and position awareness.
