Is it possible to carry out a 1G barrel roll in a modern airliner such as the Airbus A380 which is restricted to, I believe, 67 degrees max bank angle.
Can the systems be overridden to do this?
This question has been asked before but from a different angle – could a commercial airliner actually fly inverted or upside down?
It was posed in relation to the inverted flight seen in the movie “Flight 2012”
In Flight 2012, even though stoned out of his mind, the captain did skilfully manoeuvre his plane in an uncontrolled dive and put his plane in an unorthodox flight to save the day.
Yes, it is possible to fly inverted momentarily in certain planes but not on a modern airliner as there are mechanism that protect it against such a manoeuvre in a normal flight.
On the Airbus, it is not possible to bank beyond 67 degrees left or right and so it is impossible to bring the plane into an inverted position.
However, there are a few some military jets or aerobatic propeller planes that can fly for an extended period upside down, especially on air shows.
But, when a plane is not in ‘normal law’ (usually after some mechanical failure) the normal bank protection is lost. It is then possible to roll a commercial plane inverted temporarily. To date, no plane has ever done that intentionally in an actual commercial flight yet except in a simulator.
Could an Airbus A380 carry out a barrel roll?
In my opinion, I believe it is possible to fly a barrel roll (a temporary inverted flight) provided the “normal law’’ is intentionally removed by switching off some flight control computers.
A Boeing 707 once did a barrel roll in a demonstration flight (see video above)
