For jet aircraft, "long-range cruise" speed (LRC) is defined as the speed which gives 99% of the maximum range, for a given weight. This results in a 3–5% increase in speed. [8] It is also a more stable speed than maximum range speed, so gives less autothrottle movement. [9]
Aircraft such as the SR-71 Blackbird are designed to cruise at supersonic speed with afterburners enabled. Some fighter jets are capable of supercruise but only at high altitudes and in a clean configuration, so the term may imply "a significant increase in effective combat speed with a full weapons load over existing types".

On December 2, 2020, Textron updated the King Air 200 series with the 260, with deliveries expected in early 2021. The model has an improved autothrottle, a Multi-Scan weather radar, a range of 1,720 nmi (3,190 km) and a top cruise speed of 310 kn (570 km/h) with up to nine passengers. [30]
The aircraft has a cruise speed of 360 knots (667 km/h), which is 60–90 knots (111–166 km/h) higher than its predecessors. The maximum operating altitude is 25,000 ft (7,600 m) for the standard version, although a version with drop-down oxygen masks is offered, which increases maximum operating altitude to 27,000 ft (8,200 m).
Gear retraction of a Velocity on takeoff. The Velocity XL is 12 in (310 mm) longer and has a 20 in (510 mm) greater span than the SE. [3] The standard XL has a cruising range of 875 nautical miles (1,620 km; 1,007 mi) and a 75% power cruising speed of 185 knots (213 mph; 343 km/h) air speed.
The speed at which the pilot begins to apply control inputs to cause the aircraft nose to pitch up, after which it will leave the ground. [7] [26] [Note 1] V rot: Used instead of V R (in discussions of the takeoff performance of military aircraft) to denote rotation speed in conjunction with the term V ref (refusal speed). [19] V Ref
Cessna 401s and 402s are powered by 300 hp (224 kW) turbocharged Continental engines with three-bladed, constant speed, fully feathering propellers. On later models cruise power was limited to 75% to reduce cabin noise. Some aircraft have a propeller synchrophaser to reduce cabin noise and vibration. [1]
