Question: What is the primary distinction between a precision approach and a non-precision approach?
Answer options:
- A precision approach is only available at international airports. ✅ A precision approach provides both lateral and vertical guidance, while a non-precision approach provides only lateral guidance.
- A precision approach uses GPS, while a non-precision approach uses VOR or NDB.
- A precision approach allows for a go-around, while a non-precision approach requires an immediate landing.
Correct answer: A precision approach provides both lateral and vertical guidance, while a non-precision approach provides only lateral guidance.
Explanation: The primary distinction is that a precision approach (e.g., ILS, GLS) provides both lateral and vertical guidance (often to a Decision Altitude/Height), whereas a non-precision approach (e.g., VOR, NDB, LNAV) provides only lateral guidance (to a Minimum Descent Altitude).
