Following are images of a prototype morion dynamics recorder. The LED indicators on the faceplate
are for (left to right) system status, GPS receiver, local card and remote card. The button on the left
side is an encoder with push and rotary detent actions. The connector on the right side is an option
for connecting a keypad by cable for entering pilot events. Pilot events may also be entered from the
encoder. The slot at the bottom is for access to the SD Card connector inside. At the back end of the
case are the power connector (top left), the serial port (top right), the GPS antenna connector (middle left),
the remote memory card connector (middle right), the Pitot/static block and the external data connector (under
the Pitot/Static block). The third image shows the remote memory module (version A) that would normally be
mounted at the rear end of the airframe for crash survivability.

Following are images of an early test flight in a Cessna 172. They were produced using
SeeYou, a glider flight analysis program,
for post-flight processing.
The log was copied to the International Glider Commission (IGC)
format for input to SeeYou. That format, and the SeeYou program, do not use all of the
information provided by the recorder. Nevertheless, these images illustrate some of the
graphic reconstruction capabilities that are possible from logs created by the WayTrac recorder.
This reconstruction used only GPS latitude and longitude, logged at 1 Hz, plus pressure altitude
from the cabin pressure sensor, as is customary for glider logs used in competitions and to claim records.
