Departing IFR At Uncontrolled Airport - When To Turn With No Instructions

[LastXdeth]

Let's say you pick up your IFR clearance from center on the ground at an uncontrolled airport.

You then get to the takeoff runway and are subsequently release for departure without any additional instructions (no "fly heading XXX," "fly runway heading, " "proceed on course," nor "turn left/right direct XXXXX," ect., what do yall do?

Just fly straight out until your initial check in with ATC in the air OR should you start proceeding onto your cleared route that's from your clearance?

When you get the release with no departure instruction, why not just ask?

if the airport has instrument approaches, it’s also surveyed for departures. If no specific procedures are published, it has a “diverse departure area”, and once you’re above 400 feet you can make any turns you deem appropriate.

If no other direction is given, it is assumed to proceed on course once you are at a safe altitude. You will be cleared to a waypoint or destination, so the assumption is you will turn towards the next clearance fix unless otherwise directed. Usually if they assign a heading, it is to help deconflict you with other traffic until they get you on radar and establish communications.
