Centaurus
Although not on your list I've experienced these:
1)Cabin Alt warning horn - see the cabin alt moderately rising - carried out unscheduled pressurisation change to no avail - the cabin was now approaching 13000 ft so carried out the rapid depressurisation QRH which resulted in an emergency decent. The cabin did not reach 14000 ft so we did not deploy the pax oxygen.
The descent took us into extremely heavy rain and turbulence (operating in the tropics) as we had not seen on radar what we were decending into (set 1 deg or so down) I had not thought to re look further down with the radar as I was somewhat distracted by the events with the cabin pressure and the subsequent emergency decent.
Comms were a problem as ATC did not initially understand what our problem was. Probably wrongly in hindsight I initially called a PAN before I decided to execute an emergency decent - this just confused everything as ATC did not seem to understand what a PAN was. I issued a MAYDAY shortly before the emergency decent which was understood.
Returned to departure airport but before landing consideration had to be given whether to land overweight or not. As no emergency now existed I elected to extend gear and speedbrake 30 mins out to achieve MLW.
Incidentally the problem was eventually traced to a crack on the cross body duct supplying the packs. It took about 5 days to find this because this part of the duct was apparently hidden.
2)Loss of generator - start the APU which then failed - followed by divert.
3)Various other small QRH items not worth discussing.
