ALL ABOUT HUD (HEAD-UP DISPLAY)

The HUD (Head-Up Display) is the next generation of flight instrumentation; although this technology was used in military operations since the 1980s, it recently emerged in civilian aircraft operations.

Next Generation

HUD's key benefits are that it allows the pilots to view the outside world and the instruments together and eliminate the need to change the view at a critical phase of the flight. 90% of the information to fly the aircraft is attained visually by the pilots. In conventional aircraft, the pilots need to scan at least more than six instruments to fly at a moment, making eye stress and fatigue. This stress eventually creates a loss of situational awareness, making pilots miss essential data during a critical time, e.g. approach and landing phase. To put it more simply, HUD is nothing but presenting information on a see-through screen in front and allows the pilots to see the aircraft information and the outside atmosphere, making more situational awareness and avoiding delayed decisions.

History Fact

Wright brother’s first aircraft had only three instruments - A stopwatch, Tachometer, and Anemometer.
