Delta MD-90 sharp turn


#1

This Delta MD-90 just made a sharp left turn out of KMSP.
Does anyone know why they did this?

At a guess, I’d say that there is some noise abatement procedure that requires that aircraft maintain the runway heading after departure until a certain height or distance. The flight then makes a left turn onto its required track. The actual turn rate is less severe than is shown in the tracking.

Ok, thanks @belzybob

Unfortunately, every time I’ve looked at KMSP since you posted they have been taking off to the South East, so I haven’t been able to verify my guess.
