It’s an Airbus. Wank by design. You can have all the handling skills in the world and it’ll make cock all difference as the pilot is removed from the equation by computer components made in places like Wuhan.Actually, if I remember rightly, as long as the rudder is balanced with the bank angle to keep the turn-and-slip bubble in the centre of the glass then the forces are in equilibrium and nothing should spill.
I recall watching a series on BBC, when BBC documentaries were factual and not mithered in politics and agenda-driven bias, about the development of flight and they showed a guy in a twin-engined light aircraft (I think it was) with his full cup of coffee in the holder on top of the panel doing a roll (with the correct application of control surfaces) and not spilling a drop.
They also showed the test pilot for the B747 prototype's first flight having a "Sod it" moment and giving it a full roll, too. The programme for the initial flight of a new type was stated to usually be to take off, fly a circuit and land again - this one being no exception.
The cup of coffee barrel roll was a bloke whose name escapes me (Chuck T Cheeseburger III Jr?) but was a well known hotshot. In an Aero Commander IIRC. Neat trick but in reality, if flown properly (ie not by people like me) it’s a 1g manoeuvre so physics dictates the result.
The other roll was the 707, flown by Tex Somethingorother (Johnson?). Wouldn’t you just know he’d be called Tex? He was even wearing a leather bomber jacket.
