Flow Bloisi posted a topic in ArchiveHi guys, Im doing a lot of training offline ivao or vatsim network with the bubus to be full prepared when i will go into ATC condition, i keep only active sky weather.To day i simulated a too high altitude: Destination airport was LEBL with PUMAK star Runway 07 ILSLZ, fuel on board at landing about 3.2 3.5 What i dot is the following, i descent to FL290 from FL350 then i wait like 2 or 3 minutes at FL290 (for simulate approach on busy airports with a lot of plane like ivao network where the ATC can't respond quickly) after this time i pushed OP DES with middle spoilers out, descent rating was between 27000ft/mn and 3500ft/mn.The problem is i never coma back on vnav path, i was 1600ft higher when 250kt restriction come so i deployed full spoiler to slow down at 250kt but my next point was at about 7000ft and i was finishing to decelerate at 10 000ft... so finaly i was 3000ft higher, i use V/S and middle spoiler out to keep 240kt and on the Next waypoint i was about 1800ft too high. So in this case what mode use ? stay VNAV give an uncorfatble descent rate for passenger and EXPED too, V/S and OP DES are they the good way to go down quickly ? I noticed OP DES is very good below 10000ft on VOR approach, it can be very hepful to control a good speed and descent rate to the FAF.On boeing plane i was using LVL/CHG when i was to high with spoilers but in this case what i saw today is little bit different on airbus plane.Maybe i miss something ? Thanks
