I am not talking Radar Contact.In real IFR, I am totally lost with what altitude that I should maintain under various circumstances. I am overloaded with information (it feels like they are conflicting rules).could anyone simply this? :)Here is an example:Say.. I filed a "DP.Transition" from Arlington Muni, TX (near DFW) to Houston hobby Texas. ---------------------------------------------------From: KGKYDP.Transition - V111 - VOR1 - V222 - DirectTo:KHOUFlight Altitude = 7000--------------------------------------------------The DP has the route to the Transition and it has specific alititude.-------------------------------------------------I get the clearence As Filed. Maintain Rwy Heading, climb to 2000 expect 3000 in 10. (Say this altitude is different from the DP).Now what do I do?I fly the runway heading...and climb to 2000 expecting vectors.. (even though they have cleared me for the DP).1. They could say... Change frequency to xxxx.x resume Own Navigation.Now what do I do?What should be my altitude?

Do what you
