An unstable approach, including excessive descent rates.
An unstable approach, including excessive descent rates.
Bottom line
For large sink rates, drastic corrective measures would be required that, even if successful, would destabilize the approach. If an increasing sink rate is detected, it should be countered by increasing the AOA and simultaneously increasing thrust to counter the extra drag.
