Aircraft pressure fueling systems instructional procedures are normally placarded on the?

The correct answer is that aircraft pressure fueling systems instructional procedures are typically placarded on the fuel control panel access door. This is because the fuel control panel is a critical area where operators interact with the fueling system. By placing the instructions directly on the access door, it ensures that personnel have immediate access to the necessary information right at the point of operation.

This helps to prevent errors during the fueling process, as it provides visual reminders of safety procedures and operational steps that must be followed to ensure safe fueling.

In other potential locations where instructions might be considered, such as on the lower wing surface or on cabin interior panels, those locations would not provide as direct a reference for the actions needed at the fueling control panel. The aircraft ground connection point, while important, does not give the same context for fueling procedures as the fuel control panel access door. Thus, this is why the fuel control panel access door is the most appropriate and logical choice for these instructional procedures.
