I'm not real sure. Could be one or several possibilities. Turning off the lights reduces the electrical power demand. The more electrical power required will cause the generators to work harder which reduces the effectivity of the engines during take-off, the critical part of flight when the aircraft needs as much thrust as possible. Many passengers like to look out the windows and see the city. Turning out the lights reduces glare and allows you to better see in the dark. (Of course, they place the windows too low for most people to look out of them.)

How do hot tub controls work?
Hot Tub Controls have two primary functions. The first function is to provide a means for you to manually control all of the Hot Tub equipment and features, such as Pumps, Air Blowers, Lights, etc. The topside Control Panel is where you turn the equipment on and off, and adjust or set how that equipment will operate. If you have a SmartControl, you can also control Entertainment, view Slideshows, set Wellness Timers, and play Games. The second function is to automatically control the equipment for proper Filtering, Heating, Freeze Protection, and Safety. The topside Control Panel is where you adjust or set these automatic functions, such as Water Temperature, Filter Time, and Heating Mode. If you have a SmartControl, all of these functions will be controlled as efficiently as possible to save you money. A Hot Tub Control consists of two primary parts, a Control Panel up on the top, and a Controller inside the cabinet of the Hot Tub. The Controller usually consists of two primary parts, a Relay Control Board and a Water Heater. All of the equipment is connected to the Control Board, including the Heater. When you press a button on the Control Panel to turn something on or off, the message is sent down to the Control Board, and a Relay, or remote switch, is closed or opened to control the equipment. A SmartControl is much more intelligent and does a whole lot more as far as controlling a Hot Tub and other things in your back yard, displaying Video on the screen, reading your Emails, and surfing the Internet. There's some pretty cool Demos and Videos of these controls at www.newportcontrols.com.
What is the sequence of operations of gas furnaces?
Thermostat calls for heat. Induced draft fan motor starts. Vent pressure switch verifies pressure. Simultaneously gas valve opens and ignitor lights burner(ignition varies: hot surface ignitor, electronic spark ignitor, or standing pilot). Flame is sensed. High limit temperature switch is made. Blower fan runs. Thermostat calls for no heat. Gas valves close. Burners shut off. Induced draft fan shuts off. Blower fan put into fan delay(fan blower continues to run). Low limit temperature switch made. Fan blower stops.

What is the importance of rcx robot?
Robots in antiquity and through the Middle Ages were used primarily for entertainment. However, the 20th century featured a boom in the development of industrial robots. Through the rest of the century, robots changed the structure of society and allowed for safer conditions for labor. In addition, the implementation of advanced robotics in the military and NASA has changed the landscape of national defense and space exploration. Robots have also been influential in the media and profitable for toy manufacturers.HistorySignificanceRobots began as entertainment for royalty. Inventors such as Al-Jazari and Leonardo Da Vinci worked to build automatons for their benefactors. Al-Jazari built a floating band that resembled humans and performed various songs and drum beats depending on the programming of a series of pegs. Da Vinci created a automaton based on the knight's armor. It could stand and move its arms and neck, as well as open its mouth. It wasn't until 1961--when an inventor named George Devol installed his robot, Unimate, into a General Motors factory in Trenton, New Jersey--that the first modern industrial use of the robot was attempted. Unimate would lift die-cut metal pieces and stack them for the human workers. This development changed the dynamics of robotics and brought them into the workplace, making them pivotal to a business.FeaturesIndustry has benefited drastically from the expanse of a robotic work force. Automated machines have taken over the duties of dangerous and mundane jobs from humans, allowing greater productivity. Because robots never tire, extra shifts have been added to factories. Farmers have taken advantage of new technology with automated harvesters, the waste disposal industry has implemented robots in some of its dirtier jobs, and the medical industry benefits from advancements in assisted surgical robotics. The idea of a factory with no human workers has come to fruition. IBM runs a "lights off" factory in Texas completely staffed by fully autonomous robots making keyboards.The military has launched various programs in robotic technology, most successfully the Predator and Reaper unmanned aerial reconnaissance vehicles that allow a pilot to control the robot from vast distances. The vehicles can do high-altitude surveillance for long periods without having to support a live pilot, and when needed the planes can launch small strikes on targets in zones that normal aircraft cannot operate.ConsiderationsRobots' main position in society are in a capacity to assist humans by taking on the jobs that are dirty, dull or dangerous. Beyond the factory floor, robots have been instrumental in space exploration and performing other tasks that would be impossible for humans to accomplish. The Mars rovers Spirit and Opportunity lasted years longer than NASA predicted and stayed on the mission far past the time any manned mission could have functioned. The Deep Impact probe that crashed into a comet literally functioned at a capacity impossible for humans. The Chernobyl meltdown site contains radiation levels that would kill any human. As such, the Pioneer robot was developed to enter the remains of the facility to address structural stability. Also, the Dante II was utilized to enter volcanic eruptions, which are impossible for humans to investigate.MisconceptionsRobots have had a long importance in the media, between our fascination with real-life robotics and their fictional counterparts. The first instance of a robot in a film was in Fritz Lang's "Metropolis." It introduced the concept of a functioning automaton programmed to act as a human. Robots appeared frequently over the course of the next century in films such as "Forbidden Planet" and television programs like "Star Trek." Probably the most famous duo of robots ever are C-3PO and R2-D2 from the "Star Wars" films. The characters brought a humanistic attitude to the previously dry image of robots. In modern cinema, robots have portrayed heroes and villains, both elaborately sophisticated and starkly simplistic. The machines featured in "The Terminator" have long held a scary yet fascinating influence over the culture of robotics.Modern robotics are present everywhere in society, from a DVD burner in a computer to the microwave in most American kitchens. The invention of the microprocessor in 1971 caused the computerization of virtually every appliance and tool the modern home uses. Toasters and stoves utilize microprocessors that control sensors to reduce the likelihood of fires, while cellular phones implement virtual memory to enhance interaction. Most toy stores now feature hundreds of robots for educational and entertainment use. With the introduction of the "Furby" in the late 1990s, robots with limited artificial intelligence become a boon for the marketplace, generating vast amounts of revenue in simple consumer-ready robotics.
Why do airplanes have lights?
For a few reasons. The lights are used when visibility is reduced or hindered for reasons including low-lighting (dusk or dawn), nighttime, fog and clouds, and rain or bad weather. The Landing lights illuminate the ground in front of the airplane during taxi, takeoff and landing so the pilot can see in front of the aircraft. The white Strobe lights are used so that other people and aircraft can see where the airplane is located when viewing from a distance. The Right-Of-Way lights are to help other aircraft know where the airplane is heading so they can avoid a possible collision. This is done by placing a green light on the right wing tip, a red light on the left wing tip and a white light on the tail of the airplane. By observing how these lights move and where they are in relation to one another it is possible to determine the orientation of the airplane and it's direction of travel.

What does the no smoking sign on an airplane mean?
Not very long ago smoking was allowed during the flight. It was however not allowed during landing, take off and during refuelling. A no smoking sign was therefore switched on and smoking was only allowed when the captain switched off the sign. Presently, no smoking is allowed in most flights, but the lights are switched on to remind the passengers that smoking is not permitted
Can you keep the overhead lights on in an airplane during take off?
Yes, they will not do anything to the plane like having a phone or something on could.

When do airplanes turn on Landing lights?
Landing lights are placed at the airports. Airplanes do not have them. They two or three blinking lights which they put on when they fly at night. Airplanes absolutely DO have landing lights. They generally turn on landing lights when on final, established on an approach, or in general, a few minutes prior to landing. Many pilots use variations of the pre-landing check or GUMPBLES while on final or just before... Gas (on), Undercarriage (gear down), Mixture(rich), Prop (forward), Brakes (check), Landing Light(s) (ON), Engine Gauges (in the green), Seatbelts (fastened). The big guys often have flashing landing lights which generally serve the same purpose, but are obviously more visibly apparent, especially useful at busier airports where situational awareness is critical for controllers as well as nearby airplanes holding short, waiting for takeoff, or taxiing on the ground.. They also help light up the runway centerline when visibility is low or dark on landing. At 150mph, and closing in on the ground in the dark, those landing lights come in pretty handy when you're looking for that runway centerline.
How do you stay safe during a thuder storm?
