Ascent Profile - KSP 1.0.4

  1. Brakes on, Full throttle, Stage and let then engines spool up.
  2. Take-off using full runway length and build up speed to 425 m/s at sea level.
  3. Pitch up slowly to 10° above horizon, without losing speed.
  4. At 7 km start pitching down, so you’re level between 8 and 9 km and build up speed.
  5. At ~1000 m/s pitch up slowly to reach 10° above horizon before 12.5 km.
  6. At 22 km switch Rapier Mode (Action Group 1)
  7. Keep going at 10° above horizon.
  8. When AP is above 45 km point the nose Prograde.
  9. Throttle down when AP is a couple km above your desired altitude.
  10. Circularize at AP.

Descent Profile - KSP 1.0.4

  1. 80 km orbit. In Map mode, focus Kerbin and turn camera so KSC is facing towards you right above the Navball.
  2. Time warp until your spaceplane is right behind Kerbin.
  3. Put a maneuver node right where you orbit appears from behind Kerbin on the left side.
  4. Pull the retrograde marker until the maneuver is ~135 m/s dV.
  5. Move the maneuver node until the planned orbit intersects the surface through KSC.
  6. Perform the maneuver.
  7. Turn Prograde and time warp till you enter atmosphere.
  8. Keep nose 40° above horizon until your speed is around 1400 m/s. (May need to move fuel around keep stable)
  9. You should be nearing the coast of the landmass where KSC is at 25-30 km altitude.
  10. Nose down 5°-10° below horizon and aim to pass the mountains at 10 km, at 650-750 m/s.
  11. Nose down further, if needed, and aim for a point about half the runway length in front of the runway.
  12. Use brakes to slow down to around 120 m/s.
  13. At 200 m, flare and aim for the runway.
  14. Touch down with less than 3 m/s vertical speed.
