IFLY INDIGO
I am sure your operations manual will have something to say on this. Before launching operations from an airfield the company performance engineer using Airbus softwares like PEP or OFP is to ascertain that all these requirements are met. Generally with two engines SID requirements are met. If the gredient is due to terrain issue then OEI perfomance must be checked and OEI SID may have to costructed. There will be company policy on this. If you acedemically want to know then the thumb rules can be used but operationally it is not decision made in the cockpit.
