Unsafe Condition
The identification of misleading information in the emergency procedure for the ``1(2) FUEL LOW'' caution message could result in the wrong estimation of the remaining flight time in a low fuel condition, possibly leading to an uncommanded engine in-flight shut-down and forced landing, with consequent damage to the helicopter or injury to occupants.
