  2. Speed and rate of climb - Wikipedia

    en.wikipedia.org/wiki/Rate_of_climb

    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).

  3. Variometer - Wikipedia

    en.wikipedia.org/wiki/Variometer

    Panel mounted variometer for gliders, showing vertical speed in knots (kn). A variometer for paragliders, hang gliders, and ballooneers, showing vertical speed with both a ribbon indicator and a numeric readout, showing vertical speed in meters per second (m/s).

  4. V speeds - Wikipedia

    en.wikipedia.org/wiki/V_speeds

    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. Pitot–static system - Wikipedia

    en.wikipedia.org/wiki/Pitot–static_system

    The machmeter is used to show the ratio of true airspeed in relation to the speed of sound. Most supersonic aircraft are limited as to the maximum Mach number they can fly, which is known as the "Mach limit". The Mach number is displayed on a machmeter as a decimal fraction. [4] A vertical speed indicator

  6. 1 in 60 rule - Wikipedia

    en.wikipedia.org/wiki/1_in_60_rule

    This becomes very useful for estimating or correcting vertical speed settings and flight path angles (FPA) during climb, descent, or approaches. If a gradient in % is required, the numbers work out with the same rule: 1% over 1 NM ≈ 60'

  7. VAM (bicycling) - Wikipedia

    en.wikipedia.org/wiki/VAM_(bicycling)

    VAM is a parameter used in cycling as a measure of fitness and speed; it is useful for relatively objective comparisons of performances and estimating a rider's power output per kilogram of body mass, which is one of the most important qualities of a cyclist who competes in stage races and other mountainous [citation needed] events. Dr.

    Trump is expected to speed drilling permits that took an average 258 days to complete during the Biden administration, hold permit sales more frequently and increase drilling off the U.S. coast, ...

  9. Hard landing - Wikipedia

    en.wikipedia.org/wiki/Hard_landing

    The average vertical speed in a landing is around 2 metres per second (6.6 ft/s); any greater vertical speed should be classed by crew as hard. Crew judgment is most reliable to determine hard landing, as determination based on recorded acceleration value is difficult and not advisable, [ 1 ] partially because there is no recording of true ...
