Hi Mariano,
have no fear of PP event flying

It is more or less the same as you are used to.
You get your "own" plane (that's why you need to sign up for it here), sitting in the first departure airport. You need to fly all legs using the PP system of booking, and registering / PIREPing with the EHM flight logger. All legs are to be flown within the given time period. Usually each flight is bookable for about a week, with some days overlap between adjacent flights. This is to allow for weekend-only flyers, as well as weekday-only flyers to complete the tour. If you show up late (after the indicated days you can fly the leg), then you cannot book the flight in the PP system anymore, and your tour ends there and then. If you crash your plane, there will no longer be a plane available for you to book ... => exit tour. So you do need to be careful with your plane ... Luckily, the Twin Otter is very forgiving, with enormous lift at low speeds already, and a sturdy under carriage. So you can almost stop in the air, before you touch down. And you will be up in the air unbelievably soon too. This means you will always have plenty of spare runway length. Just practice a couple of landings to get a feel for what it takes to get her safely on the ground, before you actually start to fly the tour, and you'll be OK.
Whether or not you fly the tour online is your own choice. And then it is also your choice to fly on IVAO or VATSIM networks too, of cause. It is a nice way of "meeting" fellow EHM-ers, so I tend to fly PP events on line, while I fly only about 1/3 of my remaining flights online. Because of the time limitations per flight, you usually get to recognise a sort of pattern of when people have their flying time during the week. So you usually get to meet up with more or less the same people each time you fly.
Oh, and I checked: White Sands Missile Range is inoperative in FSX (don't know about X-plane, though

), so if you stray a bit, you'll be OK anyways
Cheers,
Eric-Jan
