On Monday, January 3, 2022, Southwest Airlines Flight 997 from STL to LGA landed with the following flightpath:
The flightpath deviates from the planned stabilized approach to Runway 04 and instead lands on Runway 31. This involved executing a right turn to an approximate heading of 070 degrees followed immediately by a sharp left turn to 315 degrees to line up with the runway, all within the last 90 seconds of the flight.
Why would this have been done?
To me, an amateur aviation enthusiast, it seems to me this is very much a non-stabilized approach, and I wondered why a commercial airliner would do such a thing.
Is there a place where one could find recordings of the ATC-cockpit communications during this event?
Is this kind of last-minute switch to a perpendicular runway common in commercial aviation?
Is this maneuver indicative that there was a last-minute issue with the planned approach, such as a runway incursion?
