How Braking Action Computation Function (BACF) works

NAVBLUE – RUNWAYSENSE

Use the data measured by the aircraft during its deceleration roll to identify the braking action level

Actual braking performance

Reference Aircraft Performance Model

Braking Phase

DRY GOOD GOOD to MED MED MED to POOR POOR

In simple terms, BACF compares what the aircraft actually did to

simulations of what the aircraft would have done for each reference

runway state → find the best match

Pilot Feedback on MCDU

FEEDBACK TO THE PILOT

Situational awareness about how slippery the runway was and where

(REQ) lets pilot know that information is available

AID FOR PIREP

Can be used to consolidate the pilots’ evaluation of the runway braking action for the PIREP

Why is it Free for Airlines?

The Safety Benefit of this technology can only be realized with a mass adoption of the onboard software

The value is not in one message, it is from the combination of 100s of messages.

Therefore Airbus & NAVBLUE decided to make the onboard software FOC, provided that airlines share the data with the RunwaySense platform.

Frequently Asked Questions

Number of ACARS messages sent- BACF only sends a message if a slippery condition was detected. This will vary depending on your operations and time of year, but in general it may be only 1 ACARS message per 500 landings

ACARS Message Size

- All data is fit inside one ACARS block. The message length is

maximum 208 bytes; only 35 bytes if error message.

Will this impact my current ATSU AOC customization

- No. The BACF software is loaded in the same memory partition

as the AOC customization but is completely separate. It has no

impact on your current AOC customization.

How do I route the messages to Airbus/Navblue

- The BACF messages have their own dedicated SMI Label: RSA.

Simply contact your ACARS service provider and ask them to route

a copy to Airbus/Navblue (Type-B address = XYTGU7X)

NAVBLUE – USING THE AIRCRAFT AS A SENSOR TO ESTIMATE RUNWAY BRAKING ACTION. 17

How long is installation?

- BACF will have it’s own dedicated AMM Task that will be made

available with the Technical Adaptation. Airbus does not provide an

advanced copy, but to estimate the workload you can refer to the

following AMM tasks which are very similar:

-AMM TASK 46-21-00-610-001 (Uploading of the ATSU

Software), and

- AMM Task 46-21-00-610-005 (Uploading of the ATSU

Software with a High-Speed Portable Data Loader)

How does this affect flight operations?

- The BACF works in the background and remains transparent to

the flight crew. There is no change in operations. If the flight crew

wishes to check the BACF message they can access the

information through the MCDU.

What resources are available for pilots & flights ops?

- There are two additional pages in the FCOM describing the

system.

- There is an ISI article available on Airbus World titled “How to use

BACF to File a Pilot Report of Braking Action?”

What is it?

RunwaySense improves runway

condition awareness for airlines,

airports & ATC by sharing information

on how slippery the runway is

What does it do for you?

It uses the aircraft as a sensor to

measure how slippery the runway

was at landing.

> The information is displayed to the

pilot after landing on the MCDU

and,

> An ACARS message is routed to

NAVBLUE’s collaborative web-

platform for display.

How does it help?

> Each equipped aircraft will provide

runway condition awareness in

real-time;

> Airports will be able to better

manage the operations during

difficult winter or bad weather

conditions;

> ATC and pilots will have better info

regarding the current state of the

runway for landing and take-off.
