Airfield Sign Forms
The 25 forms that make every AGL airfield sign — internally illuminated, externally illuminated where applicable, mandatory, informational, location and direction — an individually traceable engineering asset. This division carries each sign through Design/Identification, Installation, Location, Electrical Connection, Illumination, Photometry, Visibility, Compliance, Acceptance, Maintenance, Failure, Repair/Replacement and Asset Lifecycle, acting as the sign-specific control layer rather than duplicating the detailed installation, testing, photometry, calibration, cable/connector and asset-management records held elsewhere in the library.
Where this fits — Division 18 is the master documentation and lifecycle-record layer for airfield signs, integrating with Division 04 (Installation), Division 05 (Inspection), Division 06 (Testing), Division 09 (Failure Investigation), Division 11 (Asset Management), Division 14 (Calibration), Division 15 (Photometry) and Division 16 (Cable, Connector & Electrical Circuit Records). It should not duplicate those detailed records — instead every sign becomes individually traceable, from Sign ID through Location, Installation, Circuit, Transformer/Driver, Connector, Earthing, Illumination Test, Photometric Test, Visibility Inspection, Compliance, Acceptance, Asset Register, Maintenance, Failure and Repair/Replacement, into the Sign Lifecycle Record.

Frequently Asked Questions
Quick answers about the 25 Division 18 Airfield Sign forms, how they are grouped, and how they connect to the rest of the library.
Q1What is Division 18 — Airfield Sign Forms in the AGL Engineering Forms & Templates library?
Division 18 is a set of 25 airfield sign forms (SGN-01 to SGN-25) in the AGL Engineering Forms & Templates library. It makes every AGL airfield sign an individually traceable engineering asset, carrying it through identification, installation, location, electrical connection, photometry and visibility, maintenance, failure history, compliance and eventual replacement. The forms are grouped into 9 categories: Sign Installation & Identification, Sign Electrical System, Sign Photometry & Visibility, Cleaning & Maintenance, Component Replacement, Housing & Structural Control, Electrical Connection & Earthing, Compliance & Acceptance and Asset & Lifecycle Management.

Q5What is the difference between the Sign Illumination Test, Sign Photometric Test and Sign Visibility Inspection?
The Sign Illumination Test (SGN-07) verifies proper electrical and visual illumination of the sign. The Sign Photometric Test (SGN-08) verifies its photometric performance, and the Sign Visibility Inspection (SGN-09) verifies that the sign remains clearly visible to the intended aircraft or vehicle operator.
Q6Which forms cover sign repair and component replacement?
The Sign Failure Report (SGN-15) records any sign failure or abnormal condition, and the Sign Repair Record (SGN-13) documents repair of defective components. The LED Module Replacement (SGN-16) and Driver Replacement (SGN-17) forms record replacement of those components, and the Sign Replacement Record (SGN-14) documents complete replacement of a sign or major component.
Q7How is a sign accepted and tracked across its life?
The Sign Compliance Checklist (SGN-22) verifies compliance before acceptance or during audit, and the Sign Acceptance Certificate (SGN-23) certifies that an installed, repaired or replaced sign has met the applicable acceptance requirements. The Sign Asset Register (SGN-24) is the master asset record for every sign, and the Sign Lifecycle Record (SGN-25) documents its life from installation through replacement or disposal.
Q8Can the forms in Division 18 be downloaded and filled in?
Yes. Each form has a Download as Word button that produces an uncontrolled sample Word template with letterhead, a document-control block, ruled entry fields and a three-tier approval table, ready to print or fill on-screen. Checklist-format forms such as Sign Installation Checklist (SGN-01) download with a checkbox and a verified-by line for each item. The forms can also be searched by keyword or form ID.
Q9How does Division 18 connect to the other divisions?
Division 18 is the master documentation and lifecycle-record layer for airfield signs. It integrates with the installation, inspection, testing, failure investigation, asset management, calibration and photometry divisions, and it does so without duplicating the detailed records held in them.
PLACE THE SIGN. UNDERSTAND THE MESSAGE.
An airfield sign form confirms legibility and condition — but real competence means understanding mandatory vs information signage rules, colour-coding standards and what a pilot needs from that sign at that exact location.
