Advanced Brake Controller (ABC)

The Advanced Brake Control system is a sophisticated dual-channel differential braking controller, incorporating anti-skid functionality and replacing the older legacy controllers of the F-16 aircraft.
The system is in operational service on-board more than 700 Lockheed Martin’s F-16 aircraft of different blocks, serving in more than 10 different Air Forces around the world. Its superiorbraking performance, coupled with fully redundant features, provides unique
“fail-safe” capabilities.

Technical Data

• Dimensions: (HxWxL) 4.0”x5.1”x6.4” (102x130x163)mm
• Weight: 4 lb (1.8 Kg)
• Qualifications: MIL-STD-810, MIL-STD-461 and MIL-STD-704
• Power Consumption: 17 W
• MTBF exceeds 15,000 flight hours

Benefits

• Improved landing and taxiing safety by:
  • Superior braking performance on slippery runway
    conditions - icy, snowy, flooded, transitional
  • Nominal braking performance even in case of a failure
    of a control channel.
  • Nominal braking performance even in case of
    a severely degraded wheel speed sensor.
  • Auto-recording of the last 9 landings for in-depth
    diagnostics
• Improves fleet availability and reduces fleet operation
  costs by:
  •  Reducing maintenance effort
  •  Reducing brake and tire wear, provides Life-Cycle-Cost
    reduction.
  • Increasing the entire braking system’s MTBF
  •  Reducing the entire braking system’s MTTR

 Main Features

• Improved braking algorithms - Normal and Backup for effective braking on all runway conditions
• Qualified for F-16 block 15 through 60
• No aircraft modifications required - Retrofit is flight-line executable
• Full dual redundancy - two independent controllers in one LRU
• Fault detection automatically triggers the 2nd redundant braking control channel
• Advanced BIT (Built-In-Test) and diagnostics:
• Covers the entire braking system (cockpit and wheels sensors, wiring and braking pads)
• Diagnostics provides automatic fault isolation
• Auto recording of landings for in-depth diagnostics & debrief
• First failure will be isolated prior to affecting the braking performance
• Full braking performance even with a defective wheel sensor
• Special failure indicator for quick reference for flight-line technician
• Re-programmable via communication channel
• Flight-Line Test Equipment – Utilizing a laptop or a PDA unit
• NSN 1630-17-112-8746
• RSL P/N AY96011129
• LM P/N 16VL014005-1
