Does a runway need to be flat?
Does a runway need to be flat?
Answer: No, runways are not flat. They are crowned to help drain water off the sides during rain, and often one end of a runway is higher or lower than the other. When preparing takeoff performance calculations, pilots include the slope of the runway. Airplane flight manuals include the maximum runway slope allowed.
Why are some plane landings bumpy?
Poor visibility is a challenge According to Siivola, if the pilot is used to landing on a runway that has a certain width, the altitude may appear higher than usual when the runway is narrower, for example. “In this case, passengers may experience a bumpy landing,” he says.
What is a smooth landing?
Landing is one of the most critical phases during a flight. A landing which you walk away from and the aircraft is still airworthy is smooth enough for me. If we’re talking flight parameters, as Jompa said anything less than -200ft/m would be considered smooth.

What plane needs the shortest runway?
The Embraer E170 needs 1,644m (5,394 ft), while the competitive Airbus A220-100 only requires a runway of 1,463 m (4,800 ft). Of jet aircraft, the Airbus A220-100 takes the cake with the shortest takeoff distance.

How fast is a 737 going at landing?
For an average-sized commercial jetliner with typical fuel and payload, the “takeoff speed” is around 130-160 knots, or about 150 to 200 miles per hour. The landing speed is more or less the same, usually a few knots slower. With a very common 737-800 the landing speed is about 180-200 knots.

Is jet fuel a diesel?
Jet fuel is very similar to diesel fuel, and in some cases, may be used in diesel engines. A diesel engine may be more fuel-efficient than an avgas engine. However, very few diesel aircraft engines have been certified by aviation authorities.
Is Jet Fuel worse than diesel?
Jet fuel has higher sulphur content than diesel fuel, and much higher than gasoline/avgas.
What fuel do jet engines use?
Jet-A powers modern commercial airliners and is a mix of extremely refined kerosene and burns at temperatures at or above 49 °C (120 °F). Kerosene-based fuel has a much higher flash point than gasoline-based fuel, meaning that it requires significantly higher temperature to ignite.
What fuel do planes use?
Aviation kerosene
