IRS to DME / DME / GPS, DME / DME or VOR / DME / GPS or VOR
/ DME to IRS, the maximum flight time is based upon the previous
FMS Navigation Mode. If the previous FMS Navigation Mode was:
(a) DME / DME / GPS or DME / DME, the maximum flight time in
IRS Navigation Mode is 5.9 hours.
(b) VOR / DME / GPS or VOR / DME, the maximum flight time in
IRS Navigation Mode is 5.7 hours.
11. Basic RNAV (BRNAV) Or Required Navigation Performance 5 (RNP-5)
Operation:
Operations as long as the FMS Navigation Mode is VOR / DME, DME / DME or
GPS.
12. RNP 0.3 RNAV Approaches:
RNP 0.3 RNAV instrument approach procedures (in accordance with AC 20-129
and AC 20-130A) must be flown using the GPS only navigation mode. (Refer to
AFM Section 2-08-90: RNAV Approach Procedures or OM Section 03-08-90,
RNAV Approach Procedures.) The flight director is required to be coupled to the
LNAV and VNAV mode if VNAV minimums are used during the approach
(autopilot coupled or not coupled). The FMS APRCH annunciator must be
illuminated during the approach.
01-03-20: Ambient Temperature
Minimum and maximum temperatures approved for operation are shown in Figure 1:
Altitude / Temperature Operating Envelope.
NOTE:
Inadvertent encounters with atmospheric conditions
where the SAT is colder than -70°C can occur. To not
exceed structure and equipment design temperature
limits, the following minimum Mach schedule shall be
maintained until the airplane can return to operations
within the envelope:
SAT - °C -70 -72 -74 -76 -78 -80
Min - M .67 .71 .76 .80 .84 .87
