LOAD FACTOR
It is the ratio between the aerodynamic force component acting normal
to the longitudinal axis of the airplane and the airplane weight. A
positive load factor is one in which the aerodynamic force acts upward
with respect to the airplane.
BANK ANGLE
It is the airplane lateral inclination of the wings, in relation to the
horizontal plane.
PERFORMANCE INFORMATION
INPUT DATA ADJUSTMENT TO ENVELOPE
Input data outside the airplane operational envelope is usually adjusted
by the CAFM. This is particularly frequent for input temperatures, but
can also occur for input altitudes and speeds. A message indicating
that input values have been adjusted to the AFM limits will be shown in
the “Messages” tab.
BALANCED V
1
VERSUS OPTIMUM V
1
Op
timum V
1
assures the greatest takeoff weight among the V
1
dependent weights. Balanced V
1
can lead to the same takeoff weights
as the optimum V
1
, but not always, depending on the field lengths
available (TORA, TODA, ASDA), and on limitations such as brake
energy, obstacle clearance, V
1
range restrictions, etc.
When balanced V
1
is requested and a balanced takeoff cannot be
calculated, CAFM resumes calculation considering the optimum V
1
.
The balanced V
1
is always presented as the optimum V
1
, and one must
compare TOD/OEI to ASD to check whether they are equal or not, in
order to assure that a balanced takeoff occurs.
