GAO reviewed the planned modernization of equipment by the Federal Aviation Administration (FAA).
Recommendations for Executive Action
|Department of Transportation||1. The Secretary of Transportation should: retain the 135 solid-state DME's rather then purchase replacement equipment because the feature providing the capability for remote maintenance monitoring may be short-lived with the emergence of NAVSTAR, evaluate the equipment replacement priority schedule by giving appropriate consideration to the reason for system outages and revise it where necessary, and reevaluate the staff savings claimed by FAA for the VORTAC modernization program.|
