I'd say it's one of those scenarios where you have to weigh up the risk of a missed approach.
Obviously in poor weather conditions arrival spacing would be increased to mitigate the risk of LOS/WVE between departure and subsequent missed approach.
However, in conditions where statistically the %age of missed approaches is very small I'd suggest it was reasonable to apply a "deemed" separation between departures and arrivals. [Providing controllers are aware of the risk and trained appropriately to resolve/restore standard separation]
Regardless of conditions the tower controller should plan what action to take if the arrival performs a missed approach.
I'm wondering if anyone has a specific entry in their MATS 2 relating to such a "deemed" separation?
