How long does the BCU power the Stinger missile after activation, and by when must it be removed to prevent damage?

• A. The BCU powers the missile for 60 seconds and must be removed within 2 minutes.
• B. The BCU powers the missile for 45 seconds and must be removed within 3 minutes.
• C. The BCU powers the missile for 90 seconds and must be removed within 4 minutes.
• D. The BCU powers the missile for 30 seconds and must be removed within 1 minute.

Answer: (B)

The key idea here is that the BCU provides power to the Stinger for only a brief, controlled period after activation, and there’s a strict deadline for removing the unit to prevent damage from heat, wear, or residual energy. The right choice matches that safe, bounded timing: a short powered interval followed by a removal window that’s long enough to complete the task but short enough to avoid damage if left engaged. The other options either imply too long a powered period or an removal window that wouldn’t reliably protect the system, making them less consistent with how such safety-critical equipment is designed to operate.
