AnswersDriveVmu means minimum unstick speed. It is the calibrated airspeed at and above which the airplane can safely lift off the ground and continue the takeoff.
What is the VNO speed?
Vno - Maximum Structural Cruise Speed - When cruising at, and below, Vno the aircraft should not be damaged by a 30 feet/second vertical gust. It is indicated by the top end of the Airspeed Indicator's Green Arc. Smooth air only for speeds in the Yellow Arc.

What is VMC speed?
Minimum control speeds. From Wikipedia, the free encyclopedia. The minimum control speed (VMC) of an aircraft (specifically an airplane) is a V-speed that specifies the calibrated airspeed below which directional or lateral control of the aircraft can no longer be maintained, after the failure of one or more engines.

What is the definition of v2 speed?
A: V1 is the speed by which time the decision to continue flight if an engine fails has been made. It can be said that V1 is the "commit to fly" speed. V2 is the speed at which the airplane will climb in the event of an engine failure. It is known as the takeoff safety speed.

What is VMU aviation?
Rotaion Speed - VR: is the speed at which rotation is initiated but the point at which the aircraft leaves the ground (VL0F) will be a few knots higher. VMU is minimum unstick speed: It is the calibrated airspeed at and above which the airplane can safely lift off the ground and continue the takeoff.

What is the landing speed of an airplane?
For an average-sized commercial jetliner with typical fuel and payload, the "takeoff speed" is around 130-160 knots, or about 150 to 200 miles per hour. The landing speed is more or less the same, usually a few knots slower. With a very common 737-800 the landing speed is about 180-200 knots.
5
What is VSO speed?
VS Stall speed or minimum steady flight speed for which the aircraft is still controllable. VS0 Stall speed or minimum flight speed in landing configuration. VS1 Stall speed or minimum steady flight speed for which the aircraft is still controllable in a specific configuration.
6
What is the landing speed of a 737?
RE: 737-800 Landing Speed?#10937427. At max landing weight (144,000 pounds for our -800s), the flaps 30 (degrees) Vref is 150. We usually add 5 knots to that to produce a "target speed" of 155 knots.
7
What is the VREF speed?
The final approach speed is based on the reference landing speed, VREF. VREF usually is defined by the aircraft operating manual (AOM) and/or the quick reference handbook (QRH) as: 1.3 x stall speed with full landing flaps or with selected landing flaps.
8
What is takeoff safety speed?
Definition. The takeoff safety speed which must be attained at the 35 ft height at the end of the required runway distance. This is essentially the best one-engine inoperative angle of climb speed for the airplane and is a minimum speed for flight in that condition until at least 400 ft above the ground.
9
What is the maneuvering speed?
VA or maneuvering speed is the speed calculated by the manufacturer at which the aircraft will stall before exceeding maximum G loading, thus preventing damage to the air-frame. Maneuvering speed is usually determined by multiplying the flaps-up, power-off stall speed by the square root of 3.8 Gs, which is 1.95.
10
What is VX speed?
Vx is the slowest (IAS), and is the Maximum ANGLE of climb. It allows one to climb to altitude within the shortest horizontal distance. Vy is slightly faster, and is the Maximum RATE of climb. It allows one to climb to altitude in the shortest time.
11
What is the VNO speed?
Vno - Maximum Structural Cruise Speed - When cruising at, and below, Vno the aircraft should not be damaged by a 30 feet/second vertical gust. It is indicated by the top end of the Airspeed Indicator's Green Arc. Smooth air only for speeds in the Yellow Arc.
12
What is VMO speed?
If the flight manual/specification says maximum speeds are: Vmo = 350 knots, Mmo = M.82. Vmo is the maximum airspeed at which an aircraft is certified to operate. Mmo is the maximum Mach number at which an aircraft has been certified to operate.
13
What is VLE speed?
VLE — Maximum landing gear extended speed. Maximum speed at which an airplane can be safely flown with the landing gear extended. VLO — Maximum landing gear operating speed. Maximum speed at which the landing gear can be safely extended or retracted.
14
What is V speed?
Incorrectly, or as an abbreviation, some documentation refers to Vref and/or Vrot speeds as "Vr." VS. Stall speed or minimum steady flight speed for which the aircraft is still controllable. VS0. Stall speed or minimum flight speed in landing configuration.
15
How does a plane take off and fly?
A plane's engines are designed to move it forward at high speed. That makes air flow rapidly over the wings, which throw the air down toward the ground, generating an upward force called lift that overcomes the plane's weight and holds it in the sky. The wings force the air downward and that pushes the plane upward.
16
What is v2 on a plane?
This speed is nicknamed a “take-off safety speed”; it is the speed an aircraft with one engine inoperative must be able to attain in order to leave the runway and get 35 feet off the ground at the end of the runway, maintaining a 200 ft/min climb thereafter.
17
What is the VMCG?
Vmcg is defined as the minimum speed, whilst on the ground, that directional control can be maintained, using only aerodynamic controls, with one engine inoperative (critical engine on two engine airplanes) and takeoff power applied on the other engine(s).
