The reason planes cruise at high altitudes is that they burn less fuel and can fly faster, as the air is less dense. At 30,000 feet and higher, it is also possible for aircraft to avoid weather systems, making it more comfortable onboard.

A higher elevation will require a longer climb, meaning the aircraft will burn more fuel in order to reach its cruising altitude. Additionally, 35,000 feet gives more time for airline crew to address any unexpected mid-flight incidents.
At 30,000 feet and higher, it is also possible for aircraft to avoid weather systems, making it more comfortable onboard. Referred to as turbofans, the engines on modern jet-powered airliners are most efficient when used at high altitudes.
Aerodynamic altitude: If a commercial airliner flies too high, it will encounter less dense air passing over the wings to create lift. This can cause the plane to stall and fall out of control. Depending on the weather conditions and aircraft weight, this can occur anywhere between 40,000 and 45,000 feet.
Aircraft with fixed wings cannot stand still in the air, unless we are talking about VTOL (Vertical Take Off and Landing) aircraft. Lift is created by air flowing around the wing. Too little forward speed, and the wing will stall (loose lift).
A series of Navy and Air Force programs in the 1950s and 1960s used pressure vessels or pressure suits to get balloonists higher, some to above 100,000 feet. Skydiver Nicholas Piantanida set an unofficial record—123,500 feet—in 1966, but a later attempt went awry when his helmet depressurized.
Whether flying at night or during the day, pilots need to see some kind of horizon. They use this to determine the airplane's attitude. At night pilots will turn their gaze from outside to inside and use the artificial horizon. The artificial horizon is normally a simply globe split into two hemispheres.
The bigger the plane, the better! Any plane can experience turbulence, but larger planes weigh more and don't feel the impact of wind changes as much as a smaller plane. Specifically, the Airbus A380 handles turbulence very well! The A380 is a large plane mainly used for international flights.
According to the FAA's Airplane Flying Handbook (8-18), for landing in turbulent conditions, use a power-on approach at an airspeed slightly above the normal approach speed. This provides for more positive control of the airplane when strong horizontal wind gusts, or up and down drafts, are experienced.
Airplanes are designed to withstand rough conditions and it is rare for aircraft to incur structural damage because of turbulence. But turbulence can toss passengers and crew members around, potentially causing grave injuries.
At night pilots will turn their gaze from outside to inside and use the artificial horizon. The artificial horizon is normally a simply globe split into two hemispheres. Using this instrument, the pilot can determine whether the aircraft is in a climb, a dive, or rolling.
Slowest aircraftThe Ruppert Archaeopteryx has a certified stall speed of 30–39 kilometres per hour (19–24 mph). The Vought XF5U can fly as slow as 32 kilometres per hour (20 mph). The Tapanee Pegazair-100 stall speed is 45 kilometres per hour (28 mph).
All airplanes will be exposed to drag during flight. They must overcome this aerodynamic force to achieve and maintain lift. Otherwise, airplanes would essentially fall out of the sky. Air brakes are control surfaces that increase drag so that airplanes slow down during flight.
Some aircraft damage from lightning strikes includes broken lighting and windows, deformed antenna placements, and onboard electronics malfunctions. Other abnormalities or warnings on the flight deck, such as cabin air pressurization problems or false alarms, can occur after your airplane has been struck by lightning.
Security lines, lost baggage and delayed flights are some of the reasons travelers say they find hopping a plane is more stressful than going to their day job, according to a recent survey. “It's just not a routine most people are comfortable with,” said Melanie Lieberman, senior travel editor at The Points Guy.
It would seem strange that pilots would purposefully dump fuel from their aircraft at a time when fuel prices have skyrocketed. What's more bizarre is that they do it in the air while flying. Tossing fuel into the air is a safe procedure for a good reason. Additionally, it is not as wasteful as it seems.
