Is it true that an aircraft might exceed TERPS protected airspace during an immediate descent if the NAVAID is not positioned correctly?

When considering the scenario of an aircraft potentially exceeding TERPS (Terminal Procedures Publication) protected airspace during an immediate descent, it is true that the NAVAID (Navigational Aid) positioning plays a crucial role. TERPS guidelines are designed to ensure safe obstructions clearance and navigable airspace during approaches and departures.

If the NAVAID is not accurately positioned, it can lead to miscalculations in the aircraft's descent profile. This misalignment can cause the aircraft to inadvertently breach protected airspace that is calculated based on the correct positioning of the NAVAIDs. In essence, the safe altitudes and lateral separations established by TERPS depend heavily on the accurate location of these navigational aids; if they are incorrectly placed, it can compromise safety and lead to a situation where the aircraft is not adhering to the authorized descent parameters as prescribed by TERPS.

This understanding emphasizes the importance of the precision in NAVAID location to ensure that all flight operations remain within predetermined safe limits, thereby preventing any risk of violating protected airspace.
