Which of the following steps can be conducted during the EPP's 5 minute cooldown?

• A. Lowering and stowing DLT Antenna
• B. Checking tire pressure
• C. Re-aim the antenna
• D. Survey marking update

Answer: (A)

During the five-minute cooldown, the focus is on quick, safe actions that secure the system without altering its alignment or requiring extensive checks. Lowering and stowing the DLT antenna fits this purpose because it immediately protects a protruding component, reduces wind loading and the chance of damage if the vehicle moves, and can be done safely within the cooldown window. It keeps the equipment ready for the next step without needing re-calibration or data updates.

The other tasks aren’t suited for this brief period. Checking tire pressure is a broader maintenance activity that belongs with dedicated vehicle checks rather than a short cooldown. Re-aiming the antenna would change its alignment and likely require retuning or verification later. Updating survey marks involves documentation or field data work that isn’t part of the equipment cooldown procedure.
