Provide a flight-simulation mode. It is helpful to practice eVFR handling and can show wheather or not eVFR is configured the way I want to use it (airspace warnings et.al.).

Additionally, let the user set a simulation speed, e.g. real-time, 2x, 3x, 5x 10x and so on.

Besides this, simulation should be able to "jump" forward and backward to a position of the route, preferrably by moving the route-cursor with the finger (this yellow polygon thingy).
