As in the real world of flying, a headwind can be your ally. Wind reduces the speed at which you travel over ground, but it does not affect climb speed, so a strong headwind can provide pilots with a steep climb angle.
Hot, High, and Heavy. Any combination of these can produce disasterous results. Hot or high atmospheric conditions indicate thin air, which reduces aircraft performance by lengthening the takeoff roll and reducing your climb angle. Too much weight will have the same effect on aircraft performance.
This free version gives you 10 different takeoff scenarios.
