3. PRODUCT LIMITATIONS
The D2 Pocket Panel is a portable device that aids situational awareness. As the D2 does not have
TSO authorization from the FAA or other regulatory body, it is not suitable for permanent
installation in type certificated aircraft.
The D2’s Ground Speed, Altitude, Vertical Speed, and Ground Track (direction) instruments are
GPS-derived. Their indications WILL BE DIFFERENT from the airspeed, altimeter, VSI, and heading
instruments in your aircraft panel. The D2’s GPS-based indications should not be considered
replacements for any of these primary aircraft instruments. Details about each of these
differences are described in the Product Tour section of this guide.
