An F/A-18 taking off from an aircraft carrier An Embraer E-175 taking off. Takeoff is the phase of flight in which an aerospace vehicle leaves the ground and becomes airborne. For aircraft traveling vertically, this is known as liftoff.
Hard rime on trees in the Black Forest of Germany. Hard rime is a white ice that forms when the water droplets in fog freeze to the outer surfaces of objects. It is often seen on trees atop mountains and ridges in winter, when low-hanging clouds cause freezing fog.
Aircraft have different ways to take off and land. Conventional airplanes accelerate along the ground until reaching a speed that is sufficient for the airplane to takeoff and climb at a safe speed. Some airplanes can take off at low speed, this being a short takeoff.
Irregular snow crystal (I) – Subdivided into: Ice particle, rimed particle, broken piece from a crystal, miscellaneous; Germ of snow crystal (G) – Subdivided into: Minute column, germ of skeleton form, minute hexagonal plate, minute stellar crystal, minute assemblage of plates, irregular germ; They documented each with micrographs.

Mechanical removal of snow from a Learjet 35. The weight of snow on the tailplane has raised the nose into the air. Mechanical deicing using tools such as brooms, scrapers, ropes, and mops can be used to minimize the amount of fluid or heat-based deicing required. However care must be taken to avoid damaging surfaces, antennas, pitot tubes, etc.
An Aeroflot Airbus A330 being deiced at Sheremetyevo International Airport Econ Salt Spreader. Deicing is the process of removing snow, ice or frost from a surface. Anti-icing is the application of chemicals that not only deice but also remain on a surface and continue to delay the reformation of ice for a certain period of time, or prevent adhesion of ice to make mechanical removal easier.
An aircraft taking off at a higher altitude must do so at reduced weight due to decreased density of air at higher altitudes, which reduces engine power and wing lift. An aircraft must also take off at a reduced weight in hotter or more humid conditions (see density altitude). Most commercial aircraft carry manufacturer's tables showing the ...
