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 relating to a customer airline operation; determining a landing probability for both an existing approach procedure for a published landing minimum and a proposed approach procedure utilizing the revised navigation procedure model, the revised navigation procedure model including a revised landing minimum; calculating a benefit associated with a difference in the landing probabilities: the benefit including financial savings; 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.
