LHR Arr/Dep and FMS Coding 737 classic

[Olendirk]

Folks,

first time in LHR, do you have hints concerning the arrivals and also departures there? How is the FMS coding on the 737 FMS, is it reliable because LHR has no published RNAV overlay dep.

Second question: when engaging the 737 ap at 1000ft agl,what mode will it be when i put the ap lever on? is it lvl chg ?vnav in LHR makes more sense or not?


Thanks

OD
