1985 Sikorsky UH-60A Black Hawk

An avionics modernization program to provide state-of-the-art digital avionics for primary flight

Navigation and engine/systems displays

solid-state sensors and area navigation capability meeting FAA Next-Gen 2020 standard requirements:

• Large-format 6” x 8” (viewable area) portrait EFIS/MFD displays • PFD/MFD pair for both pilot & copilot (4 or 5 displays) • Each display includes built-in FMS HTAWS & digital flight recorder (no separate LRUs) • Up to four EICAS pages are customizable for customer requirements • 2x GPS/SBAS receivers with antennas

• 2x ADAHRS provide attitude source to cockpit system & AFCS allowing removal of

heavy expensive & failure prone gyros • 2x dual-channel Data Acquisition Units (DAU)

• 3x serial analog/digital converters (SAND) for airframe discrete inputs/outputs

• Radio tuning will be accomplished through the PFD/MFD display to minimize weight complexity cost & failure probability Autopilot Upgrade HeliSAS

The fully coupled autopilot and stability augmentation delivers increased safety and workload reduction benefits in a compact

lightweight package:

• Weight – less than 25lbs (this is based on the redundancy of the servos required

anticipate this weight to reduce) • Dramatically reduced pilot workload • Safer more confident command in demanding conditions • Autopilot fully-coupled with FMS & navigation radios

• Auto-recover to a neutral attitude in situations where pilot may lose visual reference

• HeliSAS equipped aircraft provide reduced pilot workloads allowing for rapid learning during flight & hover
