Importance of Aircraft Lighting

Lights are probably not the first thing that comes to mind when you think about the most important components of a functional aircraft. However, the lights are all over an aircraft, and each one of them serves an important purpose. Just as important as the lights themselves is their installation. Aircraft engineers must be up to the task of installing functional lights that don’t interfere with passenger comfort, aircraft utility, or safety. 

Exterior aircraft lights help pilots navigate, avoid collisions, land, taxi, and signal other aircraft. Because of this, the design and testing process is pivotal. Aircraft lights are typically tested by using physical prototypes under difficult conditions. Engineers can simulate these conditions digitally and test things like photometry, colorimetry, homogeneity, and overall performance in situations such as landing, takeoff, and landing. These digital simulations are easier on the budget and get the lights to market sooner.

The lights inside the cabin provide comfort, safety, utility, and general illumination. In modern commercial aircraft, lights are used to help passengers beat jet lag by recreating the time of day or night at their destination. While it’s nice to have a lighting setup that creates a pleasant experience for every passenger, the most important lights in the cabin are the emergency lights. In the case of these lights, aircraft designers are tasked with making them subtle enough to not interfere with passenger’s peace of mind while still clearly directing passengers toward exits.

Cockpit lighting plays a similar role to that of the cabin, in the sense that it provides comfort, utility, and safety. The main difference, however, is that these light systems affect how pilots perform. For example, the cockpit will be lit and colored differently depending on time of day, weather, and other external factors. Lumens produced by the cockpit instruments are optimized to allow pilots to see important data without obscuring the view of other important equipment through glare, reflection, and general eye strain.
