What indication will you see if the gear is selected down and a gear leg does not lock into place?

• A. A Green UP in the gear indication window
• B. A red UP in the gear indication window
• C. A red DOWN in the gear indication window
• D. A white N in the gear window

Answer: (B)

Gear indication on the PC-12 NGX uses both color and text to show position and lock status. When a gear is commanded down and all legs lock, you’d normally see the down status clearly indicated. If a gear leg fails to lock, the system flags that fault by displaying red and the word UP in the gear indication window. The red color warns of a problem, and UP communicates that, despite selecting down, the gear is not fully down and locked. So this red UP indication is the cue that a gear leg did not lock into place. The other visuals would represent normal operation (green) or different fault/not-available states (white N), which don’t match this scenario.
