When using 30 degree flaps, what sequence ensures proper gear retraction?

• A. Retract flaps to 15 degrees first, then positive rate – gear up
• B. Raise gear immediately after selecting 30 degrees
• C. Ignore alarm and retract gear later
• D. Gear up only after flaps reach 40 degrees

Answer: (A)

When you’re using 30-degree flaps, the proper way to retract gear is to first move the flaps back to 15 degrees, then, once you have a positive rate (climbing), raise the gear up. This staged sequence keeps the flap mechanism and gear doors clear of each other and prevents interference or a false gear alarm during retraction. It also ensures the gear retraction cycle operates smoothly under load.

Raising the gear immediately with flaps still at 30 degrees can cause mechanical interference or alarm conditions, and waiting for a non-existent 40-degree flap position isn’t a valid procedure.
