Final answer:
When encountering decreased performance windshear on final approach, it is important to monitor airspeed and altitude, apply power if necessary, and be prepared to execute a go-around if needed.
Step-by-step explanation:
When encountering decreased performance windshear on final approach, there are several actions that should be taken:
- Monitor airspeed and altitude: Pay close attention to the aircraft's airspeed and altitude to ensure that it remains within acceptable parameters.
- Apply power: If experiencing a sudden loss of airspeed or altitude, apply full power to increase thrust and mitigate the effects of the windshear.
- Execute a go-around: If the aircraft is unable to maintain a stable approach, it may be necessary to abort the landing and perform a go-around.
