AIR DATA REFERENCE (ARP) PANELS
The air data reference panels – located on either pilot’s side – enable the pilots to enter airspeed reference
pointers and barometric correction for altitude.
The air data reference panels maybe divided into three sections:
- The speed reference section
This section enables the pilot to enter several reference speeds (V
1
, V
2
, V
R
and V
T
). Both PFDs show the
same values.
- The altitude reference section
Enables the pilot to select minimum descent altitude, MDA, and decision height, DH, value.
Furthermore the radio altimeter self-test is initiated from this section of the ARP panel.
- The barometric reference section
Each PFD may have different barometric pressure settings. The last selected value is saved and
restored after the next power-on. This section allows to:
o Select the barometric pressure for barometric altitude correction
o Switch between hPa or inHg
o Set standard barometric pressure when climbing through transition altitude
