Incident at Calgary, AB


1997-12-05: ACA 277 was departing Calgary for Edmonton at 1907Z, and just after lift-off, the crew received a TCAS traffic advisory to the right and above. As the a/c passed through 1500 feet AGL, the advisory changed to a resolution advisory, 800 feet below and within 1 mile. ATC reported no other traffic in the vicinity either in the air or on the airport property. This may have been a false TCAS alert. OPI - System Safety
