Alex Jefferies 17 Posted September 24, 2014 Share Posted September 24, 2014 Hi All, Ran in to a small issue last night, I went to pre-select a climb speed on the perf page before departure in order to maintain a intermediate speed during an initial SID turn using managed climb. The aircraft accelerated correctly to the pre-selected speed but I was then unable to return to the normal managed speed and had to perform the rest of the climb using selected speed. I tried every LSK on the climb page but none allowed me to return to managed speed. Have I missed anything, or is it a small gremlin with the aircraft? Thanks guys Alex Link to comment Share on other sites More sharing options...
Emi 5161 Posted September 24, 2014 Share Posted September 24, 2014 Hi Alex, we'll check this out, thanks for the report. Could you quickly show us a screenshot which button exactly you press so that we know what exactly you do? By the way, most real world pilots would simply selected speed in such a case Link to comment Share on other sites More sharing options...
Alex Jefferies 17 Posted September 24, 2014 Author Share Posted September 24, 2014 Hi Emi, Yes that's probably the easiest way! Nevertheless I don't think this is correct behaviour so thanks for looking in to it The function I am using is on LSK 4L labelled 'PRESEL'. I typed 220 in there and I cannot then clear it once airborne. Link to comment Share on other sites More sharing options...
Valle86 0 Posted September 24, 2014 Share Posted September 24, 2014 Have you tried just to push the Speed Knob on the FCU for managed speed? Link to comment Share on other sites More sharing options...
Alex Jefferies 17 Posted September 24, 2014 Author Share Posted September 24, 2014 Hi Valentin, Yes I've tried to do that, but the speed returns to what I have entered in 'PRESEL' every time. Alex Link to comment Share on other sites More sharing options...
Alex Jefferies 17 Posted September 27, 2014 Author Share Posted September 27, 2014 In theory that's how it should work here too but the problem is there is no way to return to managed speed using the FCU or the MCDU. I will test again later but I'm definitely sure the FCU does not treat the speed as 'selected' but as a function of managed speed. Alex Link to comment Share on other sites More sharing options...
Gonzalo Ramazco 1 Posted October 1, 2014 Share Posted October 1, 2014 I already reported this issue on the AXE A320. You can't go back to managed when you use preselected speed. Link to comment Share on other sites More sharing options...

talentless 0 Posted October 2, 2014 Share Posted October 2, 2014 I think he meant to say "can't" I also reported this issue for AXE A320. Link to comment Share on other sites More sharing options...
boblyons 6 Posted October 3, 2014 Share Posted October 3, 2014 A speed constraint on a SID can be entered on the flight plan page and will be followed on takeoff in Managed mode. Bob Link to comment Share on other sites More sharing options...
Kaplan 4 Posted October 5, 2014 Share Posted October 5, 2014 I don't use all the time SID, if its necessary go head use it. Smaller airports I fly out mostly manual, if weather permitting. eg Vagar EKVG. You only specify runway for takeoff. Link to comment Share on other sites More sharing options...
Airbus339 129 Posted February 18, 2015 Share Posted February 18, 2015 Anyone is able to explain how this function works, if works? I'm getting "BAD FORMAT" message every time and I have to use the FCU button if I want a specific speed after takeoff for example Link to comment Share on other sites More sharing options...
FraPre 89 Posted February 18, 2015 Share Posted February 18, 2015 Hello, during cockpit preparation and insert FMGS data you can enter an Preselect Speed at CLB page out of F/PLN restrictions for turns or other flight manoeuvre. You enter this value and after Takeoff and passing acceleration height the value is showed as target speed on PFD. For return to the normal managed CLB Speed the FCOM write - push the SPEED KNOB, but on the Aerosoft Airbus this function dosn´t works. You must pull the speed knob, than the PRESEL SPD is showed in the speed window and thereafter push the knob for return at manged mode.

Now I ask AS if this is still planned to correct for SP3? Link to comment Share on other sites More sharing options...
Deputy Sheriffs The Dude 6537 Posted February 18, 2015 Deputy Sheriffs Share Posted February 18, 2015 Unlikely for the SP3. And I use the word unlikely, and not no, for a reason. Link to comment Share on other sites More sharing options...
