B737 FMC U11 Changes

[ImbracableCrunk]

My company is still using FMC U10.7, but I've heard U11 has finally come out.

Does anyone have highlights, synopsis, change log, etc for U11?

Just a few rumours:

• Route 2
• LNAV Improvements
• Transition Altitude & Level from airport database
• Altitude Intervention Revision
• Enhanced Takeoff Error Checking
• FMC Flight Phase Change during holding
• Connect EO SID to branch point
• Down Track RNP Alerting
• Use of airport Magnetic Variation for non-CF approach legs
• WGS-84
• Climb N1 limit default
• Runaway IRS enhancement
• Modified VNAV armed TOGA logic
• Vertical Path Monitor
• and much more...

But U11 is only for those with ACARS enabled, we don't so we can't use U11.

[None]

Would U12.0 help you? Boeing says they will come out with U12.0 soon.

Didn't they say that about U11 about 3 years ago?

RTE 2 has been a rumour for years!

I thought U11 was going into the trash can and they were going straight to U12.

The thing is real folks !

I've just flown a SFP with the U11 these days.

RTE 2 is available !

ImbracableCrunk,

I thought that too because there have been issues with momentary screen blanking and internally generated V-speeds with U11. However, some operators have chosen to go ahead with U11 and take advantage of all the good things it has to offer.

The plan is to keep both U10.8 and U11.0 in the sim and see how U11.0 performs for a while. If there are no instability issues using U11 in the sim, then it goes to the line.
