Airplanes, especially big ones, are loaded with exterior lights. Here’s what they’re all for and how we use them! <img src="http://aerosavvy.com/wp-content/uploads/2014/03/lights-Splash.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> <img src="http://aerosavvy.com/wp-content/uploads/2014/03/seuss_poem.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> Lights That Help Us See Outside We have two kinds of lights that help us see stuff. The first are Taxi Lights.  These lights are usually installed on the nose gear strut and/or each  wing. We use taxi lights the same way you use your car’s headlights.  They light up the taxiway at night so we can find the gate or the  runway. The 767 has two taxi lights on the nose gear that shine straight  ahead. It also has two special taxi lights, called runway turnoff  lights, that point slightly left and slightly right so we can see while  making turns. Landing lights are usually mounted somewhere on the  wings or underneath the fuselage. Landing lights are aimed so we can see  the runway during takeoff and landing. When landing, they start  lighting up the ground about 200 feet or so above the runway. Landing  and taxi lights are extremely  bright. We have to be careful with them on the ground, especially at  night. Turning on the lights when ground personnel are nearby can cause  serious retinal damage. <img src="http://aerosavvy.com/wp-content/uploads/2014/03/nosegear_lights1.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> Taxi and landing lights on a B-767. Locations vary on different types of aircraft. Collision Avoidance: Flashy, Blinky, and Colorful! There are a lot of airplanes flying around; especially near large  cities. It’s important that pilots can see other aircraft in the sky and  on the ground. To help us do this, all aircraft have anti-collision  lights to make them easier to spot… Colorful Position Lights <img src="http://aerosavvy.com/wp-content/uploads/2014/03/NavLights.png" alt="" class="fr-fic fr-dii fr-draggable " style="" /> Wingtip Position (Navigation) Lights On each wingtip you’ll see a red or green light. Red is always on the left wing tip, green  on the right. Why? Because ship captains back in the 1800’s thought it  was a good idea. The lights reduced nautical collisions so well, that  they are now used on all aircraft and even spacecraft. Each wing tip  also has a white light facing the rear. Some airplanes have a white,  rear-facing position light on the tail. Position lights are always on,  day and night. When pilots see another aircraft’s white position lights,  we know it’s flying away from us. When we see a red and green light in  the sky, we know another aircraft is heading towards us. The lights help  us determine aircraft position and direction – thus the name “position  lights.” Flashy, Blinky, Anti-collision Lights Nothing attracts attention better than a super bright, flashing  light. That’s why big airplanes have several of them. Red beacons are  located on the top and bottom of the aircraft. Blinding white strobe  lights are on the wingtips. The white wingtip strobes are what you see  when you stare up into the night sky and see an airplane high overhead. <img src="http://aerosavvy.com/wp-content/uploads/2014/03/Beacon_animation400px-11frames.gif" alt="" class="fr-fic fr-dii fr-draggable " style="" /> The flashing red light means the engines are running.  Stay away! Next time you are at the airport, watch the airplanes at the gates. The  red flashing lights are turned on just before engine start and are  turned off after the engines are shut down. Walking near an operating  jet engine or turboprop is more dangerous than juggling chain saws. When  ground personnel see those red lights flashing, they know the engines  are running and the area is unsafe. The white wingtip strobes are  typically turned on near the runway because they are a distraction to  other pilots on the ground. Light Switches – How do you control all those lights? <img src="http://aerosavvy.com/wp-content/uploads/2014/03/light-switches350.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> B-757 & 767 external lighting controls. Thousands of watts of light… ten switches. The external lighting  controls are located on our overhead panel within easy reach of either  pilot. The taxi and two runway turnoff lights are on the left.  The  three big toggle switches on the bottom are the landing lights. The four  black push switches control the position, anti-collision and wing  illumination lights. Bigger switches are more important. <img src="http://aerosavvy.com/wp-content/uploads/2014/03/landing_lights-night.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> 30 second exposure of a jet on final approach.

You might have noticed that we keep the landing  lights on for several minutes after take off and before landing. Landing  lights are so bright, they also make great anti-collision lights. When  we are climbing or descending near airports, we turn them on so other  pilots can see us; they can be seen for miles, even in the daytime. When  we are near cruising altitude, we shut them off. If you’re lucky enough  to be near a busy airport like Chicago or Atlanta on a clear night, you  can see a parade of landing lights headed toward the runways. <img src="http://aerosavvy.com/wp-content/uploads/2014/03/on_approach.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> Landing lights are turned ON (day & night) when near airports. © Kuhnmi source © http://aerosavvy.com/airplane-lights/ </blockquote>
