    Additional speed ranges are specified for other segments of the approach. [1]: Table II-5-1-2 Table II-5-1-2 Approach plates generally include visibility requirements up to category D. [ 1 ] : II-5-1-3 While ICAO specify a top speed of 391 km/h for Category E, there exist no aircraft with an approach speed above this.

  3. Learjet 25 - Wikipedia

    en.wikipedia.org/wiki/Learjet_25

    The Learjet 25 offers a high speed platform for business travel for six to eight passengers. Typical cruising altitudes are between Flight Level 390 and Flight Level 430 which means the Learjet 25 is capable of overflying most weather systems and congested airspace. A typical cruising speed is approximately Mach 0.76.

    Speed at which exceeding the limit load factor may cause permanent deformation of the aircraft structure. [7] [8] [9] [24] V O: Maximum operating maneuvering speed. [25] V R: Rotation 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 ...

  5. Production car speed record - Wikipedia

    en.wikipedia.org/wiki/Production_car_speed_record

    To establish the top speed for cars the requirement is, in addition to the above, an independent road test with a two-way run. The mean of the top speed for both runs is taken as the car's top speed. [ 1 ] [ 2 ] In instances where the top speed has been determined by removing the limiter, the test met these requirements, and the car is sold ...

    Although it was capable of reaching Mach 3.2+, this would result in the engines accelerating out of control and needing replacement, therefore the operational top speed was limited to Mach 2.83. [ 3 ] [ 4 ] [ 5 ] The MiG-25 features a powerful radar and four air-to-air missiles , and it still has the world record for reached altitude of 38 km ...

    B-25D Through block 20, the series was near identical to the B-25C. The series designation differed in that the B-25D was made in Kansas City, Kansas, whereas the B-25C was made in Inglewood, California. Later blocks with interim armament upgrades, the D2s, first flew on 3 January 1942 (number made: 2,290). North American F-10 reconnaissance ...

  8. Speed to fly - Wikipedia

    en.wikipedia.org/wiki/Speed_to_fly

    The speed to fly is the optimum speed through sinking or rising air mass to achieve either the furthest glide, or fastest average cross-country speed. [1] Most speed to fly setups use units of either airspeed in kilometers per hour (km/h) and climb rate in meters per second (m/s), or airspeed in knots (kn) and climb rate in feet per minute (ft ...
