Performance Initialization; Operational Example ( Cont ) - Honeywell FMZ Series Pilot's Manual

Flight Management System (FMS) for the Agusta AW139/AB139 Helicopter

PERFORMANCE INITIALIZATION

Performance initialization is required for the operation of vertical
navigation (VNAV) and performance calculations. There are three
PERFORMANCE INIT pages when CURRENT GS/FF or PILOT
SPD/FF is selected. The following example illustrates the PILOT
SPD/FF initialization. The following values are used in the planning of
the example flight plan. Actual numbers used depend on the aircraft
type.

ALTITUDE:
The default values for most performance initialization data are the
values from the previous flight or aircraft database (ACDB). Assuming
the aircraft is flown the same way each flight, performance initialization
consists of verifying the default values, making changes where
required, and entering items such as wind and weight.
Depending on the pilot--selected weight configuration, from the
multifunction display (MFD) systems dropdown menu, weights are
displayed in either pounds or kilograms.
Data verified and entered under performance initialization effects
several performance functions important to the completion of the flight.
For example, understating wind indicates sufficient fuel to complete the
flight. In reality, more fuel is required. A careful review of initialization
data is required to ensure accurate predicted aircraft performance.
All data must be entered on the PERFORMANCE INIT pages for VNAV
predictions to be displayed by the FMS.
Many values
aircraft--dependent. Actual values vary from those shown in these
examples.
