Air Navigation Aids
-
Definition: Tools and systems that assist pilots in navigating aircraft safely and efficiently.
-
Types of Air Navigation Aids:
-
Ground-Based Aids
- VOR (VHF Omnidirectional Range): Radio-based navigation system for aircraft.
- NDB (Non-Directional Beacon): Ground-based radio transmitter that emits signals in all directions.
- ILS (Instrument Landing System): Provides guidance for landing, including lateral and vertical guidance.
- DME (Distance Measuring Equipment): Measures distance to a navigation aid.
- TACAN (Tactical Air Navigation): Military equivalent of VOR/DME.
-
Satellite-Based Aids
- GNSS (Global Navigation Satellite System): Includes GPS, GLONASS, Galileo, and BeiDou for global positioning.
- WAAS (Wide Area Augmentation System): Provides GPS accuracy enhancements for aircraft.
-
Visual Aids
- Runway Markings: Standardized markings that help in the takeoff and landing process.
