PFPX - Professional Flight Planner X
Aerosoft GmbH 2013
54 55
PFPX chooses, by default, an upwind runway, which may be altered if
required. Shortening of the runway, notified by airport NOTAMs, may
be achieved by specifying the shortening of either the beginning or end
of the runway. The take-off and landing conditions that may be speci-
fied are the flaps configuration, the thrust configuration or the landing
mode, and whether the air conditioning and anti-ice will be on or off.
The results of the take-off performance calculations are your perfor-
mance limiting weights for take-off and/or landing. Pressing the Apply
button will automatically transfer these weights to the planning win-
dow Max Take-Off and Max Landing fields.
Payload
Payload is the sum of the weights of passengers, their baggage and
cargo. Passengers, of course, are not individually weighed. The standard
weights of an adult, a child, an infant and their baggage are used to
calculate the pay-load. Cargo, carried in the aircraft‘s hold is weighed
separately.
Other items like crew, oil, catering and galley equipment do not count
as Payload and are included in the Empty Weight.
Normally, airlines derive the planned passenger and cargo weight from
their booking system. PFPX can simulate this by randomly generating
passenger and cargo load.
Once the number of adults, children and infants is entered, a passenger
and a baggage weight is calculated by using default weight values ba-
sed on the type of flight and type of operation selected and the stan-
dard passenger weights defined in the configuration dialog.
Adding this weight value to the empty weight of the airplane gives the
Zero Fuel Weight. If the maximum number of passengers or Zero Fuel
Weight limits are exceeded, a warning is generated.
Payload values can be adjusted by the dispatcher as required. A special
option is to calculate the maximum allowable payload by selecting the
MAX option.
