Terrain Awareness and Warning System and Vision-1


How often do I need to update the Terrain Database in my Terrain Awareness and Warning System (TAWS) or Vision-1® equipment?

Terrain Databases are developed and released on an as-needed basis. Universal Avionics recommends that the Terrain Database be kept up to date. Please refer to www.uasc.com/home/support/tawsvision1 for more information regarding the Terrain Database.
