A320 altitude constraint during climb
Hello airbus drivers ,
It happens sometimes that in SID there are constraints at or below a certain altitude . So lets say shortly after take off at around 2000 ft or before acceleration altitude while still in SRS you have an altitude constraint at or below FL50 . And you are cleared to climb unrestricted to FL80.
So shortly after take off ,people usually put their head down into the FMGS and try to remove the alt constraint or ask the PNF to do so . ( sometimes even Speed ALT * is already reached by the time the guy clears the constraint )
If you pull open climb in SRS the aicraft starts accelerating before acceleration altitude which is not what we want.
I was thinking about the following option :
if in SRS actual speed is pulled (V2+10 ), the auto flight system will revert to open climb but it will still maintain the actual speed V2+10 . Which kind of simulates the SRS mode . SRS or open climb with V2+10 gives the same result. So noise abatement procedure is respected and the altitude constraint disregarded.
and then at acceleration altitude let's say 3000 AGL , manage the speed to accelerate to 250.
What do you think ? personally I think that going for a selected option for short term , by just pulling the speed , is a better option than a "managed option " by going into the FMGS shortly after take off to clear the constraint.
