✈️ Aeronautics Preflight Checklist

A safer launch starts with a better look at your ship.

Aeronautics Preflight Checklist is a client-only utility mod that adds an expandable preflight checklist menu to the Aeronautics Diagram item, helping you catch common ship design flaws before takeoff!

Use the Diagram to inspect your contraption and catch design issues before they turn your beautiful flying machine into a falling brick.

✅ Features

• Cream Slide-out Sidebar: A blueprint-style menu that fits perfectly with the native Create interface.
• Scrollable Warnings: Scissor-clipped scrolling list lets you view all warnings on complex ships without cluttering your screen.
• Client-Only Utility: Works on any multiplayer server running Create: Aeronautics—no server-side installation required!
• Magnifying Glass Toggle: A clean button toggles the preflight checklist panel on and off.
• Built for Builders: Keeps the engineering challenge intact. It doesn't fly the ship for you, but tells you what might go wrong before launch.

🔍 Preflight Diagnostics

The preflight menu simulates your ship's components at max power/spin to check:

• ⚖️ Mass & Lift: Displays ship mass in kpg and maximum potential lift force (in pN) generated by balloons, wings, and levitation blocks to ensure it overcomes gravity. Warns you of narrow weight margins and unpowered burners.
• 📐 Flight Balance: Checks if the Center of Lift is aligned with the Center of Mass. Warns you of potential tilt, leaning, or drift if they are offset by more than 0.8 blocks.
• 🚀 Thrust & Torque: Detects if engine/thruster placement causes pitching or yawing torque imbalances (simulated at max spin) and alerts you if any propellers have blocked airflow.
