Scenario 737 is built for First Officers transitioning to Captain, helping you develop the judgement, leadership, and decision-making required in the left seat. Command upgrade is not about memorising procedures. It’s about managing ambiguity — balancing weather, performance, alternates, crew dynamics, and layered system failures without the added pressure of time. Run a Scenario anywhere and any time, in your own time. This takes armchair flying to a totally new level. Scenario 737 develops command thinking by presenting you with millions of realistic scenarios that require decisions — not just checklist recall. Build Captain-level mindset before upgrade training begins. Designed by a retired 737NG Captain. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
