Why do pilots call out 80 knots?

A: The 80-knot call is to ensure that both airspeed indicators are functioning and indicating properly. The rudder is becoming effective at that speed, too. Q: Do any runways come to mind that are too short to abort a takeoff having almost reached takeoff speed? — Jeff, Stuart, Fla.

When an aviation radio call includes the word “heavy” as an addition to a callsign, it references an aircraft's weight. But the pilots of a 747 aren't letting ATC know they ate too many donuts at breakfast—the term “heavy” is used as a reminder to all involved that an aircraft leaves a more severe wake in its path.

With this in mind, horizontal winds (also known as “crosswinds”) in excess of 30-35 kts (about 34-40 mph) are generally prohibitive of take-off and landing. As far as how this happens, it depends on where you are in flight.

Full throttle may sometimes be needed for takeoff or a go-around, but not in normal flight. Likewise, one of the few times an automobile may need full throttle is when merging onto a high speed highway with speedier traffic.

Landing. While landing, speed is largely affected by the aircrafts current weight, commercial airplanes typically land between 130 and 160 mph (112 to 156 knots).

Pan-Pan, short for “possible assistance needed,” is used to communicate an urgent, but not emergency, situation over VHF radio, in the case of aviation, to air traffic control. Examples could include a recreational pilot getting lost, or perhaps needing to climb to a higher altitude to sort a problem out.

Why do pilots tell you how high you are? Answer: It is normally part of the welcome aboard announcement as a matter of interest. We provide the time of the flight, the cruise altitude, landmarks of interest along way and the weather.

Losing Interest or Motivation. Many people have an interest in learning to fly, but when they begin the process and realize how much is involved, they may lose interest or decide flight training is not what they expected. These reactions are perfectly normal, as flying your own plane is not for everyone.

Typical takeoff air speeds for jetliners are in the range of 240–285 km/h (130–154 kn; 149–177 mph). Light aircraft, such as a Cessna 150, take off at around 100 km/h (54 kn; 62 mph). Ultralights have even lower takeoff speeds.

Its wings have a high sweep angle of 37.5° for a fast, efficient cruise speed of Mach 0.84 to 0.88, depending on the variant.

As the plane descends into ground effect, it may actually accelerate if the engines are producing enough thrust, since in ground effect the plane requires much less power to keep flying. Power from the engines will translate into speed, if not height.

What does 747 mean? The most well known aircraft in the 7×7 series is the Boeing 747, which also goes by the nickname “jumbo jet.” The 747 made aviation history. It was designed in the 1960s as a response to an increase in air traffic. It was the largest civilian airplane in the world.

Because of aerodynamics, the cockpit level had to rise and slope back down to the main fuselage, giving us the iconic hump.
