It is also the logical phase of a typical flight (the ''climb phase'' or ''climbout'') following [ akeoff and preceding the cruise. During the climb phase there is an increase in altitude to a predetermined level. The opposite of a climb is a ''descent''. Climb operation A steady climb is carried out by using excess thrust, the amount by which the thrust from the power plant exceeds the drag on the aircraft.L. J. Clancy (1975): ''Aerodynamics''. Pitman Publishing Limited, London, The aircraft will climb steadily until the excess thrust falls to zero. Excess thrust might fall to zero as a result of the pilot's deliberate action in control of the output of the engine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Iberian Peninsula (), ** * Aragonese and Occitan: ''Peninsula Iberica'' ** ** * french: Péninsule Ibérique * mwl, Península Eibérica * eu, Iberiar penintsula also known as Iberia, is a peninsula in southwestern Europe, defining the westernmost edge of Eurasia. It is principally divided between Spain and Portugal, comprising most of their territory, as well as a small area of Southern France, Andorra, and Gibraltar. With an area of approximately , and a population of roughly 53 million, it is the second largest European peninsula by area, after the Scandinavian Peninsula. Name Greek name The word ''Iberia'' is a noun adapted from the Latin word "Hiberia" originating in the Ancient Greek word Ἰβηρία ('), used by Greek geographers under the rule of the Roman Empire to refer to what is known today in English as the Iberian Peninsula. At that time, the name did not describe a single geographical entity or a distinct population; the same name was u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Step Climb
A step climb in aviation is a series of altitude gains that improve fuel economy by moving into thinner air as an aircraft becomes lighter and becomes capable of flying in the thinner air at a higher altitude. Description Since the early days of jet aircraft and commercial travel, the technique of gradually climbing in cruise altitude as fuel burns off and the aircraft becomes lighter has been widely used by pilots. The altitude that provides the most fuel-efficient cruise (at the desired speed) at the start of a long flight, when the aircraft is fully loaded with fuel, is not the same as the altitude that provides the best efficiency at the end of the flight when most of the fuel aboard has been burned. This latter altitude is usually significantly higher than the former. By climbing gradually throughout the cruise phase of a flight, pilots can make the most economical use of their fuel. Originally, a simple ''cruise climb'' was used by pilots. This amounted to a simple, continuo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rate Of Climb
In aeronautics, the rate of climb (RoC) is an aircraft's vertical speed, that is the positive or negative rate of altitude change with respect to time. In most ICAO member countries, even in otherwise metric countries, this is usually expressed in feet per minute (ft/min); elsewhere, it is commonly expressed in metres per second (m/s). The RoC in an aircraft is indicated with a vertical speed indicator (VSI) or instantaneous vertical speed indicator (IVSI). The temporal rate of decrease in altitude is referred to as the rate of descent (RoD) or sink rate. A negative rate of climb corresponds to a positive rate of descent: RoD = −RoC. Speed and rate of climb There are a number of designated airspeeds relating to optimum rates of ascent, the two most important of these are ''VX'' and ''VY''. ''VX'' is the indicated forward airspeed for best angle of climb. This is the speed at which an aircraft gains the most altitude in a given horizontal , typically used to avoid a colli ...
