1.7.17 – Production Release

GPU: At the Aircraft

Provide Power

• Teaches how to position and prepare the GPU at the aircraft, including chocking and setup.
• Walkthrough of ignition and engine start, and confirmation of operational status on the GPU display.
• Guides trainees through connecting the GPU power cable, using the suspension hook, and activating the GPU output in the correct sequence.
• Requires cockpit communication: knocking on the fuselage and using IATA hand signals to confirm successful power delivery.
• Emphasizes handling the power cable correctly, including over-the-shoulder carrying technique to avoid tangling or trip hazards.
• Ends with placing safety cones around the cable to secure the working area.

Remove Power

• Covers the correct sequence for safely disconnecting the GPU from the aircraft after turnaround.
• Begins with requesting and receiving cockpit confirmation before shutdown using IATA hand signals.
• Trainees must turn off GPU power output and engine before unplugging the cable to prevent surges or equipment damage.
• Demonstrates safe cable disconnection, unhooking the suspension hook, and stowing the cable properly in the GPU compartment.
• Concludes with removing cones from the apron and fully powering down the GPU ignition/electronics.
• Highlights real-world error scenarios to show risks of miscommunication, skipped steps, or mishandling.
• Reinforces sequencing, situational awareness, and disciplined apron safety.

Exam

• Assessment of knowledge from the "GPU: At the Aircraft" module via 15 multiple-choice questions (pass = 12/15).
• Topics include correct GPU positioning and chocking, cockpit communication, cable handling, suspension hook use, proper power-up and power-down sequence, and cone placement.

Further Changes

• Reworked buildings across all lessons on the apron with improved lighting and increased visual depth.
• Changed order of demo lessons
• Added missing cones on all background aircraft
• Removed light poles on the apron environment that were blocking the aircraft driveway
• Fixed issue with recentering accidentally resetting trainee height
• Fixed issue in Personal Protective Equipment lesson where trainee could not select an item
• Increased significance of aircraft damage during crash animation in Belt Loader Approaching the Aircraft
• Added missing blue sleeve and suspension hook on GPU power cable in GPU Equipment 101 Controls lesson
• Added GPU attached to the aircraft during all Belt Loader: At the Aircraft lessons
