-This screen is a simplified version of the original. It shows the vertical situation during the ascent - the central section is a plot of altitude vs. inertial speed and the line is the planned ascent trajectory. If the Shuttle symbol moves above the line, it means the climbing angle is too steep and the spacecraft is too high for its velocity, if it falls below it means the ascent is too shallow. A predictor circle shows the anticipated state of the spacecraft 20 seconds in the future assuming no changes in attitude or throttle occur. This allows to plan the ascent path when flying manually.
+This screen is almost as accurate as the original. It shows the vertical situation during the ascent - the central section is a plot of altitude vs. inertial speed and the line is the planned ascent trajectory.

 In addition, SSME throttle setting is displayed.
