VMC Visual Evleteorological Conditions - Meteorological conditions expressed in terms of
visibility, distance from clouds, and ceilings equal to or greater than specified minima.
Wastegate A controllable butterfly valve in the exhaust system used to direct exhaust gasses to
adjust the speed of the turbocharger and thereby determine manifold pressure of the engine.
3.) V Speeds:
V,
Design Maneuvering Speed, and Turbulent Air Penetration Speed - The maximum airspeed at
which application of full available aerodynamic control will not over-stress the aircraft.
Equal to the square root of the limit load factor times Vsl.
VApp Final Approach To Landing Speed
-
The airspeed recommended for touchdown. Typically
equal to 1.3 times Vso.
V, Design Speed For Maximum Gust Intensity
-
Maximum airspeed at which a specified gust
(e.g, plus or minus
30
feet per second) can be withstood without airframe damage.
Vc Design Cruising Speed
-
Speed used to establish structural strength,
VD Demonstrated Diving Speed - The highest airspeed which was actually demonstrated during
certification tests of the aircraft. Equal to 1.4 times Vc.
VFE Maximum Flap Extension Speed

prescribed (extended) position. (Top of white arc.)
VE Maximum Operating Speed
-
The highest airspeed obtainable with maximum continuous
power in level flight.
VIMD Minimum Drag Speed and Maximum Endurance Speed
-
The airspeed that results in the
greatest time aloft.
VIMR Maximum Range Speed - The airspeed that results in the least amount of he1 consumed for
distance traveled.
VLE Landing-Gear Extended Speed
