Definition
A landing approach flown along a standard glidepath (typically about 3 degrees) toward a runway of standard width and length, with the pilot using the expected visual cues — runway shape, perspective, and apparent rate of closure — to judge height and rate of descent.
Plain English
A regular landing approach flown at the usual angle toward a runway that looks the way runways normally look, so the picture out the window matches what the pilot expects to see.
Context Anchor
Seen in landing and instrument-flying discussions, especially when comparing a correct approach path with paths made unsafe by visual illusions.
Derivation
Normal comes from a Latin word meaning a rule or standard. Approach comes from older French words meaning to come nearer. Together, normal approach means the standard, expected way of coming nearer to the runway for landing.
Why Pilots Care
Recognizing the normal approach profile helps pilots detect when illusions are making the runway appear too high, too low, or the wrong distance, allowing timely corrections.
Intuition Check
Normal does not mean casual or automatic here. It means the correct, standard landing path for the airplane, runway, and conditions.
Example Sentence 1
On a normal approach to a runway of standard width, the runway appears to grow longer and wider at a predictable rate as the aircraft descends.
Example Sentence 2
Optical illusions can make a normal approach look too high, causing the pilot to fly a low path and land short.
