Description
The potential for hazardous consequences after a Level Bust are increased by not properly responding to TCAS RA annunciations:
- not accurately following the guidance of an RA.
- not initiating an RA response in a timely manner.
- not ceasing an RA response in a timely manner (overshoot risk).
