Finished the HUD (head-up display) for the lander today. It’s kinda like the display in front of the pilot on a fighter plane. It displays the lander’s angle, fuel and speed. Two different configurations are available, one for approach mode and one for landing mode. Here’s the approach mode display:

On this display, the angle, fuel and horizontal and vertical speeds are displayed. Also shown on the indicators are the angle and speed limits you have to be within before you can switch to landing mode. You’ll have to rotate the lander to a horizontal position and bring the speed back to a slow hover before deploying the landing gear. Here’s what the landing display looks like:

No need for an angle indicator here, since you can’t rotate the ship anymore. Speed and fuel indicators are still available, and a horizontal position indicator, wich indicates how far away you are from the center of the landing platform. This is needed to line up the ship for landing. Ideally, you’d hover over the landing pad until you’re perfectly on top of it, reduce the horizontal speed to zero and then slowly descend until touchdown.
