Cruising flight mode - flight mode of an aircraft with a constant speed. The main range flight mode. Height at K. p. can be kept constant during the flight or increase due to a decrease in the mass of the aircraft as fuel is consumed. K. p. it is determined by two parameters - speed and height (or lift coefficient on the river shaft). [one]
Cruising flight mode is a steady horizontal flight mode. This is one of the main operational modes for civilian aircraft. [2]
The most economical flight profile for an airplane is a flight with a gradual climb as the flight weight decreases due to the generation of fuel in the fuel tanks — this is the so-called ceiling flight mode. [2]
Aircraft piston engines have a boost system that makes them economical to operate at a certain height, where maximum efficiency is achieved. Piston engines are most effective when flying at speeds of up to about 250 mph (460 km / h) and at altitudes up to 3,000 meters. [2]
The crew of a jet aircraft, as the weight of the aircraft decreases due to the development of fuel, with the permission of the ATS dispatcher, can occupy ever higher echelons in order to increase flight efficiency. [2]
Aircraft with turboprop engines are most effective for flights at speeds from 250 to 400 mph (460-750 km / h) and altitudes from 7,500 to 10,500 meters, and with turbojet - at speeds above 400 mph (750 km / h) and altitudes from 11,000 to 18,000 meters. [2]
In order to achieve cost-effectiveness, civilian flights on airways must be carried out in the most advantageous modes. [3]
In aviation, cruising speed is the speed of an aircraft in cruising flight mode [1] .
