V Speeds

VNO is Maximum Structural Cruising Speed per definition in CFR FAR Part
1. If you were to ask what is VNO? Why do some Pilots constantly
believe its Normal Operation Speed. The Green arc is the normal
operation. The yellow arc is cautionary range. The white arc is the
range in which we can use flaps. The top of the white is VFE. The
bottom of the white arc is VS0. Just like the Bottom of the green is
VS1. Of course VNE never-exceed speed is the tiny red arc and we
shouldn't go there!

So tell me what is the definition of VNO?

VA means design maneuvering speed.

VB means design speed for maximum gust intensity.

VC means design cruising speed.

VD means design diving speed.

VDF/MDF means demonstrated flight diving speed.

VEF means the speed at which the critical engine is assumed
to fail during takeoff.

VF means design flap speed.

VFC/MFC means maximum speed for stability characteristics.

VFE means maximum flap extended speed.

VFTO means final takeoff speed.

VH means maximum speed in level flight with maximum
continuous power.

VLE means maximum landing gear extended speed.

VLO means maximum landing gear operating speed.

VLOF means lift-off speed.

VMC means minimum control speed with the critical engine
inoperative.

VMO/MMO means maximum operating limit speed.

VMU means minimum unstick speed.

VNE means never-exceed speed.

VNO means maximum structural cruising speed.

VR means rotation speed.

VREF means reference landing speed.

VS means the stalling speed or the minimum steady flight
speed at which the airplane is controllable.

VS0 means the stalling speed or the minimum steady flight
speed in the landing configuration.

VS1 means the stalling speed or the minimum steady flight
speed obtained in a specific configuration.

VSR means reference stall speed.

VSRO means reference stall speed in the landing
configuration.

VSR1 means reference stall speed in a specific
configuration.

VSW means speed at which onset of natural or artificial
stall warning occurs.

VTOSS means takeoff safety speed for Category A rotorcraft.

VX means speed for best angle of climb.

VY means speed for best rate of climb.

V1 means the maximum speed in the takeoff at which the pilot
must take the first action (e.g., apply brakes, reduce
thrust, deploy speed brakes) to stop the airplane within the
accelerate-stop distance. V1 also means the minimum speed in
the takeoff, following a failure of the critical engine at
VEF, at which the pilot can continue the takeoff and achieve
the required height above the takeoff surface within the
takeoff distance.

V2 means takeoff safety speed.

V2min means minimum takeoff safety speed.

VNO means maximum structural cruising speed.

Thanks... now riddle me this. Why do they call it VNO and not VSC? The
others have initials that recall their definitions, why not this?

There are a lot of things in aviation that go against our normal
instincts or reactions. Like when you first performed an emergency
procedure your instructor reduced the power to idle. I bet your first
reaction was to lower the nose. Now you know to trade potential engergy
for kinetic and raise the nose, climb to bleed the airspeed off to
catch your best glide speed. Its a trade off.

So here is what happens with VNO. People like acronyms. So those who
were taught that VNO is Normal operation speed needed words that
matched VNO. For those of us who are anal retentive and yes I am one of
those people because I must follow strict interpretation of regulations
because I am required to do so, we'll always know that VNO is Maximum
structural cruising speed. Look in FAR part 1 under definitions.

So... your response to Jose's riddle is that "it's VNO because they called
it VNO"?

I would think that the "anal retentive" response would actually supply an
answer to how that acronym was derived, since that was the question that
was asked. We all know that we just have to memorize those things that
make no logical sense. ;-)

If there is no practical explanation, then it could be argued that it's just
"trivia."

Actually, an "anal retentive" response would recognize that VNO is not
likely an acronym at all. It might be an abbreviation or
initialization, but not very likely an acronym. But then again, only
an "anal retentive" would notice! g

You mean trade kinetic energy for potential.

Please indulge me here..

VA is where military vets get their benefits from, also a southern
state

VC were the guys in the black pajamas carrying Kalashnikovs

VD is what you end up with after buying that skanky chick too many
drinks

VH was a huge rock group from the 80's

VMU is the speed you rotate at to avoid the cow on the runway

V2 was a German rocket from WW2


I feel better now... Long day at work ya know...

.... and V8 is what you drink before a flight, when you can't have 151.
