Aircraft
On the aircraft tab you are able to specify basic aircraft properties as
described below.
• Registration: The registration consists of a prefix and up to six
characters. The prefix is usually one or two characters and de-
fines a country registration (for example N5678; N stands for
United States). A registration uniquely identifies an aircraft.
• Type: Selecting an aircraft type defines aircraft basic characteris-
tics used for flight planning.
• Engines: An aircraft type can be delivered with one or more dif-
ferent engine type(s). Different types have varying characteristics
in fuel flow and performance.
• Weight, Length & Altitude Units: Select the appropriate units the
aircraft is calibrated to. European airlines tend to use the metric
system, the United States of America the avoirdupois (imperial)
system.
• Empty Weight: Aircraft weight plus crew, oil, catering and galley
equipment (but without fuel), passengers and cargo is referred
to as Empty Weight. The Empty Weight is also sometimes re-
ferred to as Dry Operating Weight (DOW) or Basic Operating
Weight (BOW).
• Max Zero Fuel: Maximum Aircraft Weight including payload
(passengers, baggage and cargo) but without fuel.
• Max Ramp: Maximum Aircraft Weight during taxiing.
• Max Take-Off and Max Landing: Maximum structural Aircraft
Weight for take-off and landing. Note: Performance limit may
be lower than the structural limit (refer to TOPCAT – Take-off

the type of operation. Note: infants (age below 2) are not con-
sidered to occupy a passenger seat.
