-This screen becomes visible during the second part of the ascent (after SRB separation). It is a simplified version of the original and shows the same vertical situation as the previous screen, but at different scales. In addition, it offers information in throttle setting and remaining propellant. The inertial speed scale is magnified from 25.000 to 26.000 ft/s in the upper part of the screen and shows the anticipated point of main engine cutoff (marked by CO).

It is an accurate version of the original (PASS and BFS) and shows the same vertical situation as the previous screen, but at different scales.

 Predictor circles show the anticipated state of the Shuttle assuming no changes in attitude and thrust occur for 30 s and 60 s in the future. This allows to aim to near ballistic climb onto the correct trajectory when flying manually.
