Indeed overkill is better than underkill.
However I would just mention that with anything "aviation" you get huge chinese whispers and somebody reporting say "an electrical problem" is likely to be "fire in the cockpit" by the time it reaches the fire service coordinator. I once had this (and did report it was sorted by switching off the relevant bits) and got four fire engines, several ambulances, loads of stuff from all over the place. I spoke to them afterwards and indeed the information I passed to ATC when in the air got heavily modified.
The press also love aviation accidents so turn up in force. Much more fun for a low grade local hack desperate to make the grade than the latest underfunding case of a nursery school etc.
