2) The default RNP value for Approach is:
- 0.3 for airplanes equipped with Load version previous
than Load 25.3 (Pre-Mod. SB 190-31-0049 or Pre-
Mod. SB 190LIN-
31-0012) or previous than Load 25.4
(Pre-Mod. SB 190-31-0045 or Pre-Mod. SB 190LIN-31-
0009), performing any approach using FMS;
- 0.5 for airplanes equipped with Load 25.3 (Post-Mod.
SB 190-31-0049 or Post-Mod. SB 190LIN-31-0012)
,
Load 25.4 and on (Post-Mod. SB 190-31-0045 or Post-
Mod. SB 190LIN-31-0009) or with an equivalent
modification factory incorporated, performing radio-
based approach. For RNAV approaches the default
value remains 0.3.
The default RNP values above do not constitute airworthiness or
operational approval
for the respective RNP types. Refer to
NAVIGATION OPERATIONAL APPROVALS in the GENERAL
SECTION for the FMS RNP capabilities.
When the FMS is selected as the navigation source on the PFD, the
scale of the CDI will be based on the displayed active RNP value. The
two-dot, full-scale deflection of the CDI will always be equal to the RNP
value (1xRNP) displayed on the PFD.
The FMS does not provide an indication to the crew of an excessive
lateral (cross-track
) deviation. Lateral deviation is not considered in the
display of the RNP integrity alert. It is the pilot’s responsibility to
monitor lateral deviation, and take appropriate action to ensure the
airplane follows the flight plan with minimal error.
The steering sources required for each RNP type assume worst case
position determination by the FMS. Regardless of the s
ensors in use,
the RNP integrity alert will always be provided at any time the current
position determination mode of the FMS does not yield satisfactory
accuracy and integrity to satisfy the containment requirements for the
active RNP type.
NOTE: For fault-free performance, the instantaneous probability of
exceeding the integrity limit has been shown to be less than
containment integrity requirement defined in DO-236A,
however the exposure period has not been considered in the
fault-free case.
