A UPS United Parcel Service McDonnell Douglas MD-11, registration N255UP performing flight 5X-72 from Louisville,KY to Anchorage,AK (USA) with 2 crew, was enroute at FL360 about 30nm eastsoutheast of Swift Current,SK (Canada) when the crew received an "Indicated Airspeed" warning on both the captain's and first officer's primary flight display. The crew declared emergency and descended the aircraft to FL320. The "Unreliable Airspeed" checklist was worked during which the crew determined the Air Data Computer (ADC) #1 was unreliable. The crew switched the data sources to ADC #2 and the indications returned to normal, the "Indicated Airspeed" Warning extinguished. The crew continued the flight to Anchorage for a safe landing about 3.5 hours later.

The Canadian TSB reported the #1 ADC was replaced, the system checks were then satisfactory.
