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...

set of visual flight rules. The pilot can maintain or change the airspeed, altitude, and direction of flight (heading) as well as the rate of climb or...

speed of an aircraft type at which the angle of climb is largest is called VX. It is always slower than VY, the speed for the best rate of climb. As the...

Cyclone radial engine, it had a good initial climb rate of 2,750 ft/min (840 m/min) and a top speed of 277.5 mph (446.6 km/h). The aircraft was then...

("Badger") and the Tupolev Tu-95 ("Bear"). The Lightning has exceptional rate of climb, ceiling, and speed; pilots have described flying it as "being saddled...

reached a record speed of 616 miles per hour (991 km/h). Meteors also broke records in flight time endurance and rate of climb. On 10 February 1954, a...

tricycle undercarriage, STOL capabilities, twin turboprop engines and high rate of climb have made it a successful commuter airliner, typically seating 18–20...

by a new tail of greater anhedral and a vertical fin of reduced height. The Su-15 had maximum speed of Mach 2.5 and a rate of climb of 228 m/s (750 ft/s...

speed of 120 knots (222 km/h) on 20 hp (15 kW) less. It had a useful load that was about 100 lb (45 kg) more than the Skyhawk P and a rate of climb that...

interceptor. This was revised on April 1 with new requirements for endurance, rate of climb, and significantly increased range. A development schedule was approved...

200-horsepower diesel engine that increases its rate of climb and performance. Its range is 250 km (160 mi) line-of-sight and 1,000 km (620 mi) by satellite...
