Apexline: Rocket Simulator

Explore how changes in empty mass and drag affect the modeled flight of the same rocket and motor. HOW IT WORKS 1. Configure a rocket, motor and conditions in Altitude. 2. Open Flight Envelope and choose mass and drag variations. 3. Run the sensitivity check, inspect the scenarios and share the report. Motor references, stability, recovery and flight logs remain available. The mission readiness board now opens from Altitude without covering the app tabs. WHAT TO KNOW This is a model sensitivity study, not a probability interval or permission to launch. Only empty mass and drag vary. Wind, motor variation, instability and other conditions can produce results outside the displayed range. Scenario inputs are a snapshot; return to Altitude to change the baseline. iPhone and iPad.
