Abstract
A method of changing a preselect altitude value includes receiving an input from a pilot. In response, the preselect altitude value is changed by a first amount from a current preselect altitude value toward a minimum altitude value. The first amount that the preselect altitude value is changed by is dependent upon a proximity of the current preselect altitude value to the minimum altitude value such that if a difference between the current preselect altitude value and the minimum altitude value is greater than a first predetermined interval, the first amount is equal to the first predetermined interval. If the difference between the current preselect altitude value and the minimum altitude value is less than the first predetermined interval, then the first amount is less than the first interval, for example resulting in the preselect altitude value being set directly to the minimum altitude value.
