the disclosed method would be the loading of pertinent application software and electronic data pertinent electronic geographical information can be obtained from vendors such as jeppesen sanderson inc once the system is operating and has accessed the relevant geographical database the present aircraft location must be determined step 510 this step can be accomplished manually or automatically via a satellite based system such a gps or a terrestrial based geo positioning system step 515 requires the entering of the taxing or movement clearance either via datalink or by a member of the aircraft flight crew into the system this step is accomplished utilizing either an alphanumeric keypad voice touch screen datalink or other well known computer data input device the next step 520 requires the generation and display of guidance symbols to be displayed on the hud system in order to provide relevant information concerning the preferred ground speed contrasted to the actual ground speed an input signal that provides current aircraft ground speed must be provided to the hud system and monitored step 525 in addition to actual ground speed the present invention computes and displays a target speed such as a desired turn speed to assist the pilot in maintaining a predetermined maximum lateral acceleration for passenger comfort consideration or other speed limit constraints such as for an upcoming taxi hold step 530 this predetermined value of maximum.
