Private Pilot Private Exam

When approaching to land on a runway served by a VASI, the pilot must maintain what?

1. Altitude at or below the glide slope

2. Altitude at or above the glide slope

3. Any altitude as per flight regulations

4. An altitude that matches the runway elevation

The correct answer is: Altitude at or above the glide slope

When approaching to land on a runway served by a Visual Approach Slope Indicator (VASI), the pilot should maintain an altitude at or above the glide slope. The VASI provides essential visual information to the pilot about the appropriate angle of descent for a safe approach and landing. Maintaining an altitude that is at or above the glide slope ensures that the aircraft remains on the correct approach path. If the aircraft descends below the glide slope, it risks being too low for a safe landing, potentially leading to a controlled flight into terrain or obstacles. The VASI lights, typically consisting of red and white indicators, guide pilots in maintaining the correct altitude to achieve a stable and safe approach. Proper adherence to the glide slope ensures a smooth transition from the approach phase into the landing phase.
