Absolutely not required as any RAF pilot, whatever the eventual operational a/c type will have had thorough aerobatic, stalling and spinning experience which has installed as a "backbone" reaction that attitude is irrelevant to unstalling a wing and flying it out of an undesirable attitude.
Boeing & Airbus concluded 20 years ago that aerobatic competency was perishable enough to make Jet Upset training a recommendation for all operators.
I'd also suggest that there are handling issues with larger, swept wing jets worth providing training for eg: under-slung engine behavior, CofP movement and pitch authority.
Also, military training is an old chestnut with upsets and Boeing & Airbus test pilots were originally alarmed at Jet Upset programes developed by ex-fighter pilots, now airline training airmen, in the States during the late 80's early 90's. Low speed rudder use in a F15 is great for a rolling scissors and the like but in a jet airliner it is far more prone to cause controlled flight departure and massive structural failure. Evidently the courses taught low speed rudder use for roll control.
So although you may think Jet Upset training not required for ex-mil pilots both Boeing & Airbus differ.
So anyone? Has the RAAF or RAF received a package for their Airbus tankers or they behind the times with the flawed belief from 20 years ago that Airbus and it's FBW system negates this competency?
