Chapter 4. NAVAIDs

Section 1. General

4-1-1. PURPOSE

This chapter provides guidelines and procedures for nonrulemaking actions related to requests for the establishment, relocation, modification, and discontinuance of NAVAIDs.

4-1-2. POLICY

a. Various types of NAVAIDs are in use today, each serving a specific purpose in the National Airspace System (NAS). These aids have varied owners and operators, but the FAA has statutory authority to prescribe standards for the operation of any of these aids that are used as part of the NAS.

b. Dates for commissioning, discontinuance, or conversion of NAVAIDs that are part of the NAS must coincide with associated aeronautical charting dates.

4-1-3. RESPONSIBILITY FOR FREQUENCY SELECTION

The Interdepartmental Radio Advisory Committee (IRAC), which is composed of representatives of various Federal agencies, has delegated to the FAA the responsibility to manage frequency selections/assignments for all NAVAIDs. The frequency is selected by the regional Frequency Management Office as set forth in the FAA's 6050 series of Orders. Military and other government proponents apply for frequency authorization to the FAA through their respective headquarters. Non-Federal proponents must file with the Federal Communications Commission (FCC) and must only be notified of the frequency selected after the FCC/IRAC action is completed.

4-1-4. GOVERNING CRITERIA

Order 7031.2, Airway Planning Standard Number One - Terminal Air Navigation Facilities and Air Traffic Control Services; Order 7031.3, Airway Planning Standard Number 2 -Air Route Traffic Control; and other pertinent agency orders contain criteria governing the establishment of NAVAIDs.

4-1-5. LONG-RANGE PLANNING
