It seems that some of these GIMME's are Boeing features however the Boeing products have just as many of their own GIMME's too.
This was touched upon above with a ? but not answered:
- gimme an FMGS that won't throw me out of DES or CLB mode when leaving NAV for HDG
A Boeing feature, or should I say a Honeywell feature on the Boeing spec FMS and not on the Airbus spec FMGS...same manufacturer makes them for both A & B.
Boeing eqivalent keeps the aircraft in V-NAV (Boeing CLB/DES) when HDG SEL is engaged, whereas Airbus's change to Open CLB/Open Des when HDG is engaged. Actually a point IMHO to the Boeing way as it try s to keep to the planned vertical profile even when off the LNAV/NAV routing. However there are an equal number of frustrations, such as why when FLCH is engaged (certainly on the 777) the Speed Intervene (Selected Speed window opens)? AIrbus keep to the FMGS/FMS speeds, ie slow down below 10,000 etc. Win one---lose one.....your CEO/CFO pays his/her money etc etc
