Incident at Calgary, AB


1997-09-17: CDN 662 was on approach to Runway 34 at Calgary, when the crew received a TCAS resolution advisory about 1000 feet AGL. The R/A was to climb (with no red indication), so the Captain initiated a climb by levelling the nose, at which time the R/A "yellow" indication disappeared. When the nose was lowered again, the R/A came back, but with no advisory to climb. An uneventful landing was carried out, and the only reported traffic in the area was a helicopter.
