Please can someone explain why they feel the need to tell ATC that they have a problem if no assistance is required?
If you want to tell someone about your flight today, why not save radio bandwidth and post it on PPRuNe or Flyer? Someone will be interested, or at least pretend to be.
But if you want ATC to do nothing about your failed vacuum pump or whatever why are you telling them?
I am not being provocative, I honestly don't understand.
