In aviation:
- Localizer Type Directional AidLocalizer Type Directional AidA Localizer Type Directional Aid is a type of localizer-based instrument approach to an airport. It is used in places where, due to terrain and other factors, the localizer antenna array is not aligned with the runway it serves. In these cases, the localizer antenna array may be offset A Localizer...
