Audio and visual warnings activate when the aircraft is at or below which altitude settings?

• A. Primary
• B. Secondary
• C. Primary and Secondary
• D. Above Primary

Answer: (C)

Two preset altitude limits control the warnings: a primary setting and a secondary setting. The warnings are designed to trigger when the aircraft is at or below each of these limits, so you get alerted as you descend through either threshold. This dual threshold setup lets you have an earlier alert at the higher (primary) setting and a later alert at the lower (secondary) setting, providing two levels of situational awareness. The other options would not capture both alert levels or would imply warnings only above the primary limit, which isn’t how the system is intended to behave.
