HT717-1 Handheld Tester

The HT717-1 is a convenient easy-to-use tool for test and maintenance of aircraft systems that are tied to the Digital Flight Data Recorder (DFDR). It is a self contained handheld tester that displays the user specified data received from a Digital Flight Data Acquisition Unit (DFDAU) or DFDR output databus.

In an aircraft the DFDAU samples, conditions, and digitizes or reformats the analog and digital signals representing flight data. This data passes from the DFDAU to the DFDR and back on special ARINC 573 or 717 Harvard biphase encoded serial databuses. The HT717-1 provides access to the flight data by reading these Harvard biphase databuses or the bipolar auxiliary output for a Quick Access Recorder (QAR).

Operation

When connected to an ARINC 573 or 717 databus, the HT717-1 automatically senses and adjusts to the bit rate. It then synchronizes to the sync words in the serial data stream. Status is continuously reported including the bus speed, state of the sync, and current subframe and superframe. To display a particular flight data parameter the operator specifies the word by entering the desired word number, subframe, and superframe. The display is updated each time the specified word is received. Subframes and superframes may be specified uniquely or as odd, even, or all.

Menu Selections

Several menus provide added versatility by allowing the operator to select the following operational and display features. ARINC 573/717 words are 12 bits long and are displayed in binary and simultaneously in either octal, hexadecimal or decimal. To provide for non-standard and older 573 equipment, reversed and non-standard sync values and reversed data display may be selected. Since superframes are not defined in the standard, the superframe location may be specified in a menu.
