The top of descent is usually calculated by an on-board flight management system, and is designed to provide the most economical descent to approach altitude, or to meet some other objective (fastest descent, greatest range, etc.). The top of descent may be calculated manually as long as distance, air speed, and

Flight levels [3] are described by a number, which is the nominal altitude, or pressure altitude, in hundreds of feet, and a multiple of 500 ft.Therefore, a pressure altitude of 32,000 ft (9,800 m) is referred to as "flight level 320".

Common narrowbodies like the Airbus A320 and Boeing 737NG cruise at Mach 0.78 (450 kn; 830 km/h), [2] [3] while modern widebodies like the Airbus A350 and Boeing 787 cruise at Mach 0.85 (490 kn; 900 km/h). [4] [5] The typical cruising altitude for commercial airliners is 31,000 to 38,000 feet (9,400 to 11,600 m; 5.9 to 7.2 mi).
The first derivative of the A320 was the Airbus A321, also known as the Stretched A320, A320-500 and A325. [9] [25] Its launch came on 24 November 1988 after commitments for 183 aircraft from 10 customers were secured. [9] [26] The aircraft was to be a minimally changed derivative, apart from minor wing modifications and the fuselage stretch ...
In aeronautics, a descent is any time period during air travel where an aircraft decreases altitude, and is the opposite of an ascent or climb.. Descents are part of normal procedures, but also occur during emergencies, such as rapid or explosive decompression, forcing an emergency descent to below 3,000 m (10,000 ft) and preferably below 2,400 m (8,000 ft), respectively the maximum temporary ...
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. [1] 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).
