...I start up the PMDG 737/700, with running engines, open the FMC, select departure, select via/goto, select arrival, select RW ext with 10NM, select ZFW - cost index - temp - FL, select PERF, select V1, VR, V2. Arm spoilers, RTO, setting the FL in ALT sel, press the TO/GA button - and I have a "beeping" sound while rolling until lift-off. Climb to Cruise-level , TC then TD. The problem is that the plane is approaching the ARRIVAL way too high - not locking to the ILS- localizer, - set in the radiopanel - therefore not engage the APP- mode and GS. As an example the aircraft is at 5000 feet 5 NM from the arrival RW, and 3000 is selected altitude at 10NM from RW. Can anyone help me?Roar Kverneng
