If you need to add or correct the online version and the next printed version of the "Avionics Magazine" Aerospace Acronyms Guide, please contact the editor:

Thank you for sharing this important guide to abbreviations here, my friend. There is a lot of useful content here, all of which will help me understand these abbreviations better. This is what I want!
Code combination of 4096 four-digit transponder codes
The accepted definition of "number" is the ten Arabic numerals from 0 to 9. The "four-digit" transponder code is octal and contains only the Arabic digits 0 to 7. Therefore, the total number of combinations is only 4096 (8 is increased to the fourth power) and 10,000 (10 to the fourth power).
Suggested change: From: Code combination of 4096-bit four-digit transponder code To: Code combination of 4096-bit four-digit transponder code
