AUTOLAND: System & Functions

Autoland:

1965: First automatic

approach & autoland performed

by a BEA-Trident from Paris to

Heathrow.

1968: First Commercial A/C

certified with CAT II (Trident)

and CATIII (Caravelle).

Further Functions:

• Traffic Alert and Collision Avoidance System (TCAS) with automatic

trajectory change by autopilot in case of TCAS alert.

• Use of GPS information to consolidate A/C positioning and motion.

• Foundation for more advanced functionalities (ROPS, BTV, etc.).


ROPS: Runway Overrun Prevention System

Is there enough runway to safely stop the aircraft…

• ROPS performs a real time in-flight landing distance assessment for

dry & wet runways with respect to computed landing distance available.

• If the remaining runway length is too short, ROPS triggers a cockpit

alert to go around or to set maximum deceleration means.

• ROPS provides visual and aural alerts with simple procedures.

Certified by:

EASA, FAA, CAAC

Major Enhancement on A350 (2017) (Extension to contaminated Runway)

ROPS: Runway Overrun Prevention System


BTV is an auto-brake mode under supervision

of ROPS. The function actively adapts the

braking level to reach the targeted exit taxiway.

BTV: • Guarantee to vacate at the pilot selected exit.

• Optimisation of braking energy.

• Optimisation of Runway Occupancy Time (ROT)

• Improvement of passenger comfort.

• Automated MAX Braking for ROPS.

SUMMARY: Aircraft Data Exchange supports more and more Automation

…

What could be next…? Why not exchanging more information

with other connected A/C or the ground?
