I believe the AIM uses "ready for departure".



Thanks Steve, I feel vindicated. I use "xxx tower, N3351W ready for
departure runway xx". I assume if I've gotten a clearance from ground
or clearance delivery that tower has gotten a strip on me. I can't
recall ever getting an IFR lost by the tower. I've had strips dropped
on occasion crossing sector boundaries, but those are always quickly
resolved. I certainly would yell if tower told me to squawk or remain
VFR after departing on an IFR clearance, as it puts the onus on me to
get back into the system if I want to be in the system.
