Teledyne's High-Speed Data Loaders provide convenient digital data interchange between airborne and ground-based computers via a standard 3.5-inch HD (1.44MB) PC-compatible media. Serving as a removable mass storage device used by multiple airborne computers, an ADL or PDL can load navigation databases and operational flight programs as well as perform multi-volume data recording and blank disk formatting.

Throughput of the airborne computer interface has been optimized to provide the highest possible performance via dual-speed ARINC 429 data busses (8-in, 4-out) and ARINC 702 standard open/ground discretes (4-in, 4-out). The second disk drive in the PDL permits a 2-disk 1M Word navigation database to be loaded in a single operation, eliminating disk change delays.

The Loaders accept either 28VDC or 115VAC, 400Hz aircraft power. All connector pins have built-in transient protection.

Effectiveness of operator interaction is enhanced by the 16-character, alphanumeric display, providing concise messages to aid in determining load progress and simplifies troubleshooting. Detailed error reporting and diagnostics are also available via the EIA232/422 serial console port.
