The Situation
• In the early ‘90s, airlines recorded record losses
• Air Transport Association estimated the cost of delays at
$3.5B per year - some avoidable, some unavoidable
• “National Committee to Ensure a Strong Airline Industry,”

major commercial industry whose minute-by-minute operating
efficiency was capped by the daily operating efficiency of the
federal government - except for the airlines.”
• Growing recognition that the ATM system was not making
significant progress toward taking advantage of advances
in CNS and computing technology
• Summer’s of 1999 and 2000 – Record setting delays, high
visibility press coverage, Congressional hearings, growing
public awareness of issues
