In a description of a helicopter that rolled over:

o destravamento do coletivo já seria suficiente para induzir uma atitude de giro à esquerda na aeronave

thanks!

Roll Attitude

It has to do with "how much" an aircraft (fixed wing or not) is rolling in one direction.

EDIT:

Just to make things a bit clearer, an aircraft can roll, yaw or pitch.

When it rolls, it turns on its longitudinal axis. When it pitches, it goes up or down. When it yaws, it turns left or right on a perpendicular axis to the wings (if it's a fixed wing aircraft) or main rotor (helicopter).
Peer comment(s):
agree coolbrowne : Luckily this is the correct answer, since the "explanation" is wrong for a helicopter roll (not yaw) refers to rotation about the main rotor axis, which tends to be (close to) vertical. As it happens that’s what " giro (à esquerda)" means here.

My doubt here is if the helicopter rolled on its side (as if the cyclic was pushed to the side) or around the main rotor (as if an anti-torque pedal was pressed)

turning (over) action

i.e. an action that will enable the helicopter to be turned back over, onto it's 'feet'. HIH.
Peer comment(s):
disagree coolbrowne : Sorry, but it's not "turning (over)" but rolling around the main rotor (vertical) axis

banking attitude

"to bank" = Tip laterally - "the pilot had to bank the aircraft"

Bank attitude control is controlling the angle made by the lateral tilt of the rotor and the natural horizon, or, the movement of the helicopter about its longitudinal axis. After interpreting the helicopter’s bank instruments (attitude indicator, heading indicator, and turn indicator), cyclic control adjustments are made to attain the desired bank attitude.

Hey Judith. If by "giro" the author means spinning around the vertical axis, then the correct term in English is yaw.
http://en.wikipedia.org/wiki/Flight_dynamics

Roll and bank have the same meaning.

The anti-torque pedals are located in the same position as the rudder pedals in a fixed-wing aircraft, and serve a similar purpose, namely to control the direction in which the nose of the aircraft is pointed. Application of the pedal in a given direction changes the pitch of the tail rotor blades, increasing or reducing the thrust produced by the tail rotor and causing the nose to yaw in the direction of the applied pedal. The pedals mechanically change the pitch of the tail rotor altering the amount of thrust produced.

disagree coolbrowne : Sorry, but it's not "banking" (which is more relevant for fixed-wing aircraft) but rolling arounf the main rotor (vertical) axis

You are wrong. Giro = yaw. Next time you disagree with someone, please post references. Thank you.

...a left turn attitude..

Giro in this context is a turn of the Helicopter

cause the aircraft to spin to the left

Yaw would be Ok if it were an ocilating movement.

The term "attitude" doesn't sound right here, though I admit it may be the correct technical term, but "spin attitude" and "roll attitude" get very few hits as aeronatical terms leaving me a bit dubious.
