Why automated flight computers often waste fuel during your rocket's ascent to orbit
In short: Scott Manley demonstrates why timing your gravity turn is critical for orbital efficiency. By comparing manual launches against automated Mechjeb flight profiles, he illustrates how starting your turn too early or too late burns unnecessary fuel, debunking common but flawed advice found in many online tutorials.
Achieving orbit in Kerbal Space Program requires a precise gravity turn, a maneuver that balances vertical ascent with horizontal velocity. Manley uses the Kerbal-X rocket to show that rigid, automated flight parameters often fail to account for optimal efficiency. By testing various turn timings, the video highlights the clear performance gap between generic automation and a well-timed manual ascent.
This comparison serves as a corrective to the poor guidance frequently shared in community tutorials. It emphasizes that while tools like Mechjeb are useful, they are not inherently superior to a pilot who understands the underlying physics of atmospheric drag and orbital mechanics.
