1. A method for illustrating potential benefits resulting from revised navigation procedures to a customer, said method comprising: preparing a model for a revised navigation procedure; determining a landing probability for both an existing approach procedure for the published landing minimum and a proposed approach procedure utilizing the revised navigation procedure model, the procedure model including a revised landing minimum; calculating a benefit associated with a difference in the landing probabilities; and validating the revised navigation procedures through demonstration and use of the revised navigation procedure model on a computer-based flight simulation program accessible by multiple users.
