During the operational test, how long must the outriggers be fully deployed?

• A. 60 seconds
• B. 120 seconds
• C. 90 seconds
• D. 150 seconds

Answer: (C)

Outriggers must have time to fully extend, settle, and confirm all safety interlocks before proceeding with the rest of the test. The standard duration for the operational test requires ninety seconds of full deployment. This window ensures the outriggers reach complete ground contact, the system stabilizes, and the interlock checks are satisfied, giving a stable platform for safe operation.

Choosing other durations would either risk incomplete extension and unstable setup, or indicate unnecessary delay in the test procedure. Ninety seconds strikes the right balance to verify proper function and stability.
