separation
Kind of depends on what sort of RWY separation the ATCO is using. Basically said if there is enough space between the both of you there is no need for major coordination, however since a g/a is an *unusual* situation there will be coordination done anyway.
The way I look at it is... the landing a/c will usually climb better then the departing a/c lighter, TOGA power etc. the stress level for the go around crew is usually much higher as well so I tend to try to keep it simple, safe and sound for the g/a. The departing crew can usually without problems stop climb.
e.g. SID to Alt 4000... go around initiated whilst dep is passing 1000ft then just tell the dep to stop climb at 2000. by the time the go around actually is realised or can be dealt with it is usually already climbing though 2000ft or higher because boy do they like to climb ;-)
Hope that makes sort of sence, probably doesn't but anyway bottom line is: always depends on the situation and aircraft type involved. Mostly reclear the departure and let the go around climb or simply if they are too close, turn them in oposite directions!!!!!
