As mockingbird said, isn't too hard really. The hardest part is judging when to engage the throttle mode so you don't overshoot the carrier or find you've got into a hover too soon and have to spend ages nosing forward

But with some practice and if you don't try to rush things its all good

Ye, vertical landing is how pretty much all landings on a STOVL carrier done, although there are now and again a few Shipborne Rolling Vertical Landings (SRVL) which is basically the jet landing a bit like a normal plane on a runway, but has its nozzles pointing down but still going at a bit of speed so its wings are crating some lift, which enables it to bring back more weapons/fuel than normal but requires the deck to be clear of all aircraft so the jet can roll to a stop in a few meters, where in a vertical landing only one landing pad needs to be clear, which also enables multiple aircraft to land at the same time.

While it is just about possible to do an SRVL ingame, its a bit tricky as you need to balance your throttle quite a lot to get it right and timing is a bit key factor too.
