What triggers the aural landing gear position warning tone?

The aural landing gear position warning tone is designed to alert pilots to potential issues with the landing gear configuration before landing. This warning can be triggered by multiple scenarios related to the landing gear's status.

For instance, if the gear handle is not positioned in the DOWN configuration, if the power control lever (PCL) is below a mid-range setting, if the aircraft's airspeed is below a certain threshold, and if the flaps are UP, these conditions signify that the aircraft is not properly prepared for landing, thus warranting a warning tone.

Additionally, the warning can also be triggered if all landing gear are not indicating down and locked while in the landing flap configuration (LDG), indicating that at least one gear may not be secured for landing.

Moreover, if there is weight on the wheels yet the gear handle is not DOWN, this signifies that the aircraft is on the ground but not in the correct landing gear configuration.

In summary, the correct answer encompasses the full range of scenarios that can initiate the aural landing gear position warning tone, reflecting the system's comprehensive safety features. Thus, the option that states any combination of the conditions listed will trigger the warning tone is the most accurate.
