When would you use the Electrical Override switch?

• A. When the landing gear lever control box fails, bypassing the PSEM and commands gear extension in the same sequence as normal
• B. When hydraulic pressure is available
• C. When the gear is already extended
• D. When the electrical system fails

Answer: (A)

The Electrical Override is a back‑up path for extending the gear when the normal control electronics aren’t available. If the landing gear lever control box or the PSEM fails, this switch bypasses the PSEM and sends a direct electrical command to the gear actuators, causing the gear to extend in the same order as it would during normal operation. It’s not about whether hydraulic pressure is available, and it wouldn’t help if the electrical system itself has failed. It’s also not needed if the gear is already extended.
