Icao Calc

Here is the original Applet to convert a US aircraft registration (N Number)to the corresponding ICAO address and strapping for various Mode S transponders, Satcom systems, and Artex Elt.

Browsers using the MS JVM will need to use this version. To use the main version upgrade to the Sun Java (JVM) browser plugin at www.java.com.

Any strapping changes should always be verified with a Mode-S test set for transponder changes, or other methods for satcom, such as log-on verification or satcom diagnostics.
