Guidance Signs

An internally illuminated elevated sign carrying mandatory instruction (white on red), information (black on yellow) and location legends along the taxiway. Internal reflective lighting fills the face evenly, leaving no shadow to swallow a character seen at an angle; frangible poles run through the extruded aluminum box, so it stands the wind yet breaks away instead of damaging an aircraft. The front door opens without tools and lifts off, and the driver is modular, so a repair is a part swap, not a sign removal.

An elevated internally lit stand identification sign with a flat black-on-yellow face, turned towards the arriving aircraft to show the stand number. A gas strut behind the front frame lifts the door, so one person can clean the face; a labyrinth path inside keeps rain and dust out of the electrical compartment. Two face sizes, 2290×2000 and 1635×2000, use 16 or 10 light bars and draw 96 or 60 VA, so circuit load is known before installation.

An internally lit elevated sign showing white digits on black, set at intervals along the runway to tell a crew on the roll how much runway is left ahead. Internal reflective illumination lights the digits evenly and without shadows, so one glance at speed is enough; the front frame opens without tools and lifts clear of the box, keeping runway-side cleaning inside a short closure window. Posts running through the extruded aluminum frame hold the face rigid in wind.

An elevated internally lit stand identification sign with a triangular black-on-yellow face, standing ahead of the stand for the crew to check the number. Its 1200×2000 face is lit by 26 light bars from a single driver at 130 VA, which keeps the wiring simple and leaves one driver type to stock; servicing goes in through the rear door, so the front panel seal is never disturbed. The 4.5 mm UV-shielded polycarbonate panel neither yellows nor cracks under sun and grit.
