What is the difference between Terrain Advisory and TAWS?
There is some confusion in the avionics industry relating to the various terms used for terrain awareness, terrain advisory, and terrain alerting systems. Not all terrain systems are certified to Class A or B TAWS standards specified in FAA TSO C147b. If a terrain system is certified and approved to FAA TAWS standards, then the manufacturer will specifically use the term "TAWS" and/or "Class A/B TAWS". In most if not all cases, the term "terrain advisory" should not be understood to indicate "TAWS" or imply the product meets TSO C147b.
What is the difference between the different Sandel part numbers?
Similar to other manufacturers, the ordering or catalog part number is different than the part number actually printed on the physical unit. Sandel uses a numbering scheme for ordering new systems that begins with 5 numbers (ex. 90131). However, this part number is not on the actual dataplate of the unit. The part number on the unit will usually be similar to the model number with numbers following it (ex. ST3400-000).
