Who to contact first?
Here's the scenario - departing an uncontrolled airport underneath Class D airspace in Canada, flying to that class D airport IFR. Initially uncontrolled VFR and contacting for clearance to climb to controlled IFR.
Who would you contact for your clearance?
A) Would you contact Departure Frequency for the Class D airport because you are departing an uncontrolled airport?
B) Would you contact Arrival Frequency for the Class D airport because you are arriving at the Class D controlled airport?
Scenario 2 - departing an uncontrolled airport underneath Class D airspace in Canada, flying to a different location other than the Class D airport.
Would the answer be different? Or would you still contact Departure? Arrival? for clearance?
