1. An assembly for aircraft, said assembly comprising:
a first nacelle element that can be placed in a flight position in relation to a second nacelle element, the first nacelle element and the second nacelle element each being a cowl,
a locking device moveable between a locking position able to maintain the first nacelle element in flight position and an unlocking position able to release the first nacelle element,
a key configured to cooperate with the locking device in such a way as to move the locking device between the locking position and the unlocking position, the key being able to be withdrawn from the locking device only when the locking device is in locking position,
an indicator for indicating the position of the locking device, said indicator being able to take a first state and second state, and
a control device configured to be at least one of activated and deactivated by said key when the key is withdrawn from the locking device, the activation of the control device resulting in moving the indicator from the first state to the second state,
wherein the indicator is a visual indicator,
wherein the control device comprises a circuit including a switch configured to be moved by the key between an open position and a closed position, a branch, and a computation member electrically connected to the indicator, and
wherein in the closed position of the switch, electric current circulates through the branch to the computation member such that the indicator is in the first state, and in the open position of the switch, the electric current does not circulate through the branch to the computation member such that the indicator is in the second state.
