Notice of proposed rulemaking (NPRM).
Summary
The FAA is proposing to amend its regulations to reflect technological advances that support area navigation (RNAV); make certain terms consistent with those of the International Civil Aviation Organization; remove the middle marker as a required component of instrument landing systems; and clarify airspace terminology. The proposed changes are intended to facilitate the transition from ground- based navigation to new reference sources, enable advancements in technology, and increase efficiency of the National Airspace System.
