Thank you Vilas, I'm glad you read it the same way.
The FCTM reference however , within the realms of a BA verbal reasoning test, is quite clear that VAPP prior to activation is on the basis of 'estimated landing weight' and after activation it's on the basis of 'current gross weight' - there is no 'at the time of application' there.
Reference is FCTM SI 90 'VAPP determination without failure' - last 6 sentences before the equation. It's all the point scorers needed to provide rather than providing assumed opinion, pearls of wisdom and vitriol.
