Cruise altitude is usually where the higher ground speed is balanced against the decrease in engine thrust and efficiency at higher altitudes. 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).
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". In metre altitudes the format is Flight Level xx000 metres.
Separation at cruising altitude (aircraft passing below). Air traffic controllers apply rules, known as separation minima, to do this. Pairs of aircraft to which these rules have been successfully applied are said to be separated: the risk of these aircraft colliding is therefore remote.

The Airbus A320 is a low-wing airliner with twin turbofans and a conventional tail. The Airbus A320 family are narrow-body (single-aisle) aircraft with a retractable tricycle landing gear and powered by two wing pylon-mounted turbofan engines. After the oil price rises of the 1970s, Airbus needed to minimise the trip fuel costs of the A320.
