Well, we do a landing distance required performance calculation prior to every approach. The result from the EFB has an extra safety factor margin of 15% added. So, provided that Asian LCC does likewise, the EFB result is OK and the approach stable, why not? Flying a Flap 3 approach and landing in the A320 produces a lower noise footprint, saves 9kgs fuel and is recommended by Airbus. Also, we are reminded of our social and environmental responsibility to try and fly as efficiently as possible thereby reducing CO2 emissions, Penguins lives matter too.
