If you're in the States and looking to add it to you FAA ATP, you need to do a minimum of 20 hours dual and 35 solo. Could be done in 4-6 weeks. No writtens, only a checkride (incudes the oral of course)
Many people call them choppers, especially in the US and the US is as far a I know a lot bigger than the UK, so why would anyone here tell you what word you should use.
I have a friend, Capt. 747 with BA, and he says to people if they ask I fly the Jumbo!!!!
