Question about fly speeds and takeoffs

[Stalker0]

I'm just full of questions lately

Alright, so lets take a dragon with ground speed 60 and fly speed 100 for our example. He's on the ground and wants to take off. What does he have to do?

In order to move 5 feet off the ground he has to move at least 10 feet ahead, but does he also need to move half his forward speed to complete the takeoff?

And how much speed would he have left. He started the move on the ground, using his ground speed, but he finishes the move in the air (now with his fly speed). How much movement does he have left in his move action?

Nothing special, just start flying.

The angle of inclination is given for the maneuverability and since the overwhelming majority have crap maneuverability, they generally have to move 5ft laterally for every 5ft of height. But, note that that costs 15ft (5ft + 2x5ft). The next square ('voxel', really) would cost 20ft (5ft lateral + 5ft diagonal + 2x5ft vertical). To stay aloft the dragon needs to move half his speed. In general you don't normally have to worry about this for dragons, but count the total movement, including altitude (though don't count double movement costs for the height portion).

And how much speed would he have left. He started the move on the ground, using his ground speed, but he finishes the move in the air (now with his fly speed). How much movement does he have left in his move action?

Unfortunately there are no rules on mixed-mode movement. Generally, I tend to use fractional movement or, if it happened in game, a quick estimate. So if the dragon has ground speed 60 and fly 150 and move 30ft along the ground before taking to the air, he would have 75ft of fly speed remaining and would have to use it all laterally or use his second move action to continue flying (or perhaps start hovering).

Make up whatever seems reasonable to you. There are no good rules for this.
