Verlinden 1/72 NAS flight line equipment

the four-spoke wheel (three spokes in the kit, part H) attaches where the instruction sheet shows it. It sticks out a good end

the 'mailbox' is light gray

the three thin wires, to be connected on the left of the front side, are for the 3-phase electrical power for the aircraft

the compressed air hose fits to the elbow pipe, pointing down, on the right side

there are two red marker lights, to prevent vehicles running into the box in the dark

none of the photos below shows the lower flange of the box

the photos don't allow a dimensional check, since the boxes and the aircraft are at an angle to each other. The boxes are placed perpendicular to the taxiway, but the flightline's parking spot are at ~30 degrees to the taxiway

this box provides only compressed air to the aircraft, for engine starting

the box provides no electrical power to the aircraft, but the box itself is electrically powered. Otherwise the red light wouldn't work, for example.

the 'fuel supply unit' in the instructions is misleading. The 'speed bump' contained housed high-pressure air piping and electrical power lines. There was a high pressure air plant and air storage tanks on the side of the flight line.

some photos show the air starter box connected to underground high pressure air piping, instead of a 'speed bump'.

the tilted box on the left side of the 'speed bump' is an electrical power junction box, that provides electrical power to the aircraft to be started.
