greater)
• 2 A/P and 2 F/Ds capable of LNAV and VNAV * (for RNP less than
0.15)
Note: Go-around/missed approach is required if the UNABLE REQD
NAV PERF-RNP, FMC DISAGREE, or VERIFY POSITION
alert is displayed unless suitable visual reference is established
and maintained.

displayed
• review RNP availability predictions
• verify that the approach RNP is equal to or greater than:
YK981 - YQ456

• set current local altimeter (remote altimeter settings not allowed)
• verify that wind is within limits published for the approach (if

• verify that the reported airport temperature is within published limits
for the approach
• review the maximum IAS for each segment of the approach as
determined by aircraft category and applicable regulatory airspeed
requirements.

allowed as long as the maximum
published speed is not exceeded. No
other lateral or vertical modifications
after the IAF may be made.
