Positive Rate/Positive Climb?
Could somebody please explain why after Take-Off in the Boeing FCTM the PM calls Positive Rate where as in the Airbus FCTM the PNF calls Positive Climb.
Apparently it's to do with where their get their information from. i.e. one determines it from the VSI and the IRS where as the other determines it from the Altimeter and the ADIRU which in the manufacturer's eyes determines the climb away.
Any substantive info would be welcome.
