Aviation: The hidden wonders of airplanes

Engineers say the design leads to significant fuel savings over long flights. This ensures that passengers can see the emergency path lighting and other critical signals more clearly.

Airplane toilets

To some, the presence of a toilet in an airplane remains a mystery, with many wondering where the human waste goes.

The compartments are usually located above the passenger cabin or in the cargo hold and contain bunk beds and other amenities for the crew.

Oxygen mask mystery

The oxygen masks that drop down in case of cabin depressurization provide about 10-15 minutes of oxygen supply to passengers.

The supply time is designed to last until the pilot can descend to a safe altitude where breathable air is available. The time is usually sufficient for an emergency descent.

Airplane mode

Passengers are always advised to switch their phones to flight mode. The real concern is interference with the cellular network on the ground and communication in the cockpit.

High-speed movement can cause your phone to connect to multiple towers quickly, which can overwhelm the network.

Airplane food

Most people hate airplane food terming it tasteless. However, this is not the case. Scientists have revealed that the low humidity and high altitude dull human taste buds, especially for sweet and salty flavors.

However, to compensate, airline chefs often add extra seasoning to make meals more palatable at 30,000 feet.

Why airplane lights dim during takeoff and landing

Pilots always dim cabin lights during takeoff and landing. Contrary to the belief among many that this is to save battery power, dimming the lights helps passengers' eyes adjust to the darkness in case an emergency evacuation is required.
