Question

What two conditions require an ILS or LOC approach to be discontinued?

Answer 1

An ILS or LOC approach may be discontinued if the pilot receives an alert indicating an unsafe approach or visually acquires the runway environment before reaching the decision altitude or height.

Step-by-step explanation:

An ILS (Instrument Landing System) or LOC (Localizer) approach may be discontinued under two main conditions:

1. If the pilot receives an alert from the onboard instruments indicating an unsafe approach, such as an abnormal descent rate or deviation from the centerline of the approach path.
2. If the pilot visually acquires the runway environment before reaching the decision altitude or decision height.

These conditions are important to ensure the safety of the aircraft, as well as the passengers and crew on board. The ILS and LOC approaches are designed to provide precise guidance to the pilot during low visibility or poor weather conditions.
