Hi

What is being being used as a Vls speed on the A320 family (its ok to combine the A318 , 19 20 and 21 variants as Airbus does for many performance data points)

I need to establish a general Vls speed so I can calculate a safe Vapp (approach speed ) in CONFIG 3

(that’s full flaps gear extended)

I’m looking for close to real numbers without making a full blown chart factoring various weights

Please don’t respond with crazy speed rates base on 100% guessing if you don’t mind.

I know some of you are working with A320 approach speeds based on real world calcs.

I just can’t seem to nail this down

thanks Doug
