Table 4 THAAD launcher Practice Test

Pallet elevation should stay essentially level during setup and operation. In most launcher systems, the pallet needs to sit flat so the missile rail, sensors, and boot mechanism align correctly and the vehicle remains stable. Elevation angles wrap around at 360 degrees, meaning 0 degrees and 360 degrees represent the same horizontal orientation. A narrow tolerance around that level is standard, because even small tilts can affect alignment and performance.

The acceptable range of 354.29 to 360 degrees corresponds to about -5.71 to 0 degrees, i.e., a small deviation below horizontal up to perfectly level. That tight band ensures the pallet is nearly flat, which is what you want for proper operation. The other ranges describe steep or inverted orientations—30–60 degrees would tilt upward, 90–110 degrees is close to vertical, and 180–200 degrees would be upside down—clearly unsuitable for a stable, accurate setup.
