Vsi Operating Speeds

  • Flight Instruments: The Vertical Speed Indicator (VSI)

    The vertical speed indicator is one of the six basic flight instruments in an airplane. The VSI tells the pilot whether the airplane is climbing, descending or in level flight. The vertical speed indicator also gives rate information in feet per minute (fpm) for the climb or descent.

  • Variable frequency drive basics theory - Variable Speed Drives

    A constant torque load draws the same amount of current regardless of the motor's operating speed. This creates a problem at very low speeds, because the VFD reduces motor frequency in order to decrease motor speed. If the motor produces a high level of heat while operating at low speed, overheating results.
