Obstacle clearance areas and climb profiles are based on missed approach parameters from the DA, NOT balked landing parameters.
underfire, I'm sure you're right, but could you explain a little further for this ignorant amateur?
Aren't obstacle clearances defined for takeoff climb* from a point far ahead of any missed approach or balked landing? Different configuration, yes, but even so, if initial climbout on missed approach / balked landing is on runway heading as usual, then even if you balk at the last moment surely you're still well above the takeoff climb profile?
(* obviously assuming a runway that's used for both takeoff and landing!)
