APPROACH CLIMB SPEED
It is the go-around speed in the approach configuration, with one
engine inoperative, approach flaps, and landing gear retracted.
LANDING CLIMB SPEED
It is the go-around speed in the landing configuration, with all engines
operating, landing flaps, and landing gear extended.
LANDING REFERENCE SPEED - V
REF
It is the stabilized approach speed that is maintained down to the 50 ft
height above the landing surface.
MAXIMUM BRAKE ENERGY SPEED - V
MBE
It is the highest speed from which the airplane may be brought to a
sto
p without exceeding the maximum energy absorption capability of
the brakes.
V
1
/V
R
RATIO
It is the ratio between V
1
and V
R
. V
1
can never exceed V
R
, therefore
the maximum V
1
/V
R
is 1.00.
V
2
/V
S
RATIO
It is the ratio between V
2
and V
S
. Regulations set a minimum value for
this ratio, assuring safe airplane handling in climb after takeoff. For
each flaps position, there is a certified V
2
/V
S
range.
FIXED V
2
/V
S
It is a specific value for the V
2
/V
S
ratio defined to be considered in the
calculation of the maximum takeoff weight.
OPTIMUM V
2
/V
S
The optimum V
2
/V
S
is the ratio, within the certified range, that assures
the best takeoff weight, based on the fact that the takeoff weights
limited by field length, climb and obstacle clearance are directly
affected by its value.
