# Can the Boeing 777X take off without its wingtips extended?

*aerospace · news · 2026-05-07 · Simple Flying*

## Key points

- The Boeing 777X is physically and electronically prevented from taking off with wingtips folded.
- Takeoff thrust is blocked by the aircraft's systems if wingtips are not fully extended and locked.
- Unlike military designs, the 777X's folding wingtips are only for gate compatibility, not aerodynamic flexibility.
- The system uses redundant mechanical locks, sensors, and software to ensure configuration cannot be bypassed.
- Any folding mechanism failure grounds the 777X; no degraded takeoff configuration is allowed or certified.

**Companies:** Boeing
**Countries:** United States
