How does an aircraft HUD work?
A HUD projector sends critical flight, navigation and aircraft energy-management data to a glass screen, called a combiner, hanging at eye level between the pilot and the windshield. The coating reflects green to illuminate the HUD’s symbology, because the human eye is most sensitive to that color.
Are there cameras on airplane bathrooms?
No, airplanes (commercial aviation) do not have cameras in the bathrooms, or as they are called, “lavatories”. That would be illegal. If your finger, “touches” the reflection of your finger, it only means that there isn’t a layer of thick glass over the reflective material.

How does HUD operate?
Essentially, HUDs work by projecting a reversed image on to the windscreen, which is then reflected directly into the driver’s eyeline. Cars with a head-up display will often feature a strange rectangular shape on the top of the dashboard ahead of the dials; this is where the image is actually shone from.
Why don’t more planes have a head-up display (HUD)?
Because of the weight and complexity of conventional HUD systems, they are less common in smaller aircraft. The Boeing 787 is the first large commercial aircraft to offer a HUD as standard equipment, using a Rockwell Collins head-up guidance system.
How does an aviation HUD work?
Aviation HUDs are designed so that flight information appears to be on the same visual plane, so pilots don’t need to refocus their eyes when looking back and forth between projections on the screen and the exterior environment.
When were HUDs first used on planes?
Rudimentary HUDs were first developed for World War II aircraft, and became widely used in military applications during the 1960s. The first civil application of the technology was introduced in 1993. 1 Today, these systems are commonplace in both military planes and large commercial jets.
Why do airlines use HUDs and HGS?
With less go-arounds, diversions and cancellations because of low-visibility, you save fuel and keep operations on schedule. It’s why so many of the world’s premier airlines, business and regional operators, military tankers and transports, and even NASA rely on our HUDs and Head-up Guidance Systems (HGS).
