AIRBUS LPC : Landing performance with MEL or ECAM

[lion-g]

Hi Guys,


Tried looking for references but to no avail.


According to LDPA, there is a difference in terms of landing distance for the same fault, for example, brakes deactivated when we insert as MEL as compared to ECAM alerts.


Why is there a difference for the same fault?


Thank you.

Pictures needed.

Sometimes people set up LDPA with dispatch conditions and try out an MEL item, but later, when going to ECAM fault, the app changes to in-flight automatically. This provides for different results and could confuse the user.

Hi,

Thanks for the response.

The calculations were done in INFLT condition. Just the difference in the AIRCRAFT STATUS selection.
MEL - 2 Brakes deactivated vs ECAM - 2 brakes released. Rest of the conditions remain the same.

Cheers

What sort of Airbus is it? In our A320s you can't dispatch with 2 brakes inop so perhaps it's only allowing 1 brake inop to be selected and sent across from the MEL to the landing module?

With pictures, we could replicate the results and see. No pictures, no fast way forward

I can replicate it.

Generally I have seen many discrepancies in the Flysmart landing module (ECAM entries) and I have reached a point which I stopped trying to explain everything, it's not possible. In the end of the day, you are legal. Let the French guys try to figure out.
