TAKEOFF DATA SETTING
The Takeoff Data Setting function is provided in order to enable the
pilot to input reference data into the FADEC prior to takeoff. Such data
will be used to calculate N1TARGET during takeoff. The following data
has to be input:
− Takeoff Mode (T/O MODE), which corresponds to:
− T/O-1 or ALT T/O-1 (A, A1/1, A1 or A3 engines).
− T/O or ALT T/O-1 (A1P or A1/3 engines).
− E T/O, T/O or ALT T/O-1 (A1E engine).
− Reference Takeoff Temperature (REF TO TEMP), which shall
correspond to the Static Air Temperature (SAT) on the ground
provided by the Air Traffic Control Tower, ATIS (Automatic
Terminal Information Service) or other accurate source.
− Reference Takeoff Anti-Ice Condition (REF A-ICE), which is the
anti-ice system condition (ON/OFF) that the FADEC will
consider to calculate N1TARGET.
This function is enabled during ground operations only and with thrust
lever angle below 50°, before or after engine start.
The takeoff data setting is performed through the Takeoff Data Setting
controls (STORE button and SET control) on the overhead panel.
After selecting the takeoff page on the MFD, The Takeoff Data Setting
procedure shall be as follows:
a) After the first pressing of the STORE button, the MFD indicates the
following initial values for the three takeoff data:
− T/O MODE: T/O-1 for A, A1, A1/1 and A3 engines;
T/O for A1P or A1/3 engines;
E T/O for A1E engine.
− REF TO TEMP: T2SYN (if engine is running) or
ISA Temperature (otherwise).
NOTE: - T2SYN is the synthesized total air temperature at the
engine fan inlet.
- T2.5 is the fan discharge total air temperature.
− REF A-ICE: OFF.
An arrow points to T/O MODE line. Through the SET Control the
takeoff mode ALT T/O-1 may be selected.
