What the Runway Lights Are Telling the Pilot
Airfield lighting is a colour-coded instrument read from the air. White edge lights turn amber over the final six hundred metres; centreline lights alternate red and white in the last nine hundred metres and go solid red for the final three hundred; green marks where the runway begins, red where it ends. Nothing out there is decorative.
Read that way, the lighting is not a system to memorise but a countdown that tells a pilot how much runway remains without a single glance inside the cockpit. Learners who are taught the colours as a list forget them; learners who are taught them as remaining distance do not. Deliberately left off screen is anything that could be mistaken for operational authority: approach minima, specific aerodrome procedures, and any figure that a pilot might fly on belongs in the AIP and the operations manual, not in a training explainer.
The template breaks the subject into nine scenes: one establishing the approach viewpoint, four taking the light groups in the order a pilot meets them, one on the approach slope indicator and what two red and two white mean, one on how the picture changes in low visibility, one on taxiway colours and why they differ, and one on what a partial lighting failure looks like.
