Aircraft tab, ICAO Mode S Code field does not use hexadecimal notation #513
Description
Most tools to lookup/convert a registration number to its ICAO Mode S Code output hexadecimal and not decimal notation (e.g., https://www.avdelphi.com/, https://www.avionictools.com/icao.php). Accepting hexadecimal numbers would obviate the need to convert it to decimal prior to entering.
Ideally, it would nice if Avare would do the lookup for me. Perhaps, as an optional step (e.g., a Lookup button).
