3. Hold altitude under 1km until 320m/s, then start climb at 20 degrees,
4. After reaching 7km, hold altitude until 280m/s, then
5. Initiate descend to reach Mach 1.5 (~500m/s) before 1 km altitude,
6. With Mach 1.5 - hold altitude, set prograde to 15 degrees and start climb,
7. At 24km, when vertical speed delta decreases - activate AG3 to assist,
8. When Airbreathers stop, switch them to closed cycle with AG5,
9. After Apoapsis climbs to 55km, switch Airbreathers back with AG5+deactivate with AG1+2.
