I have been taught that we are not supposed to follow an Obstacle Departure Procedure unless the tower is closed. Has anybody else heard this before?
I found this in the AIM 5-2-8 "ODPs are recommended for obstruction clearance and may be flown without ATC clearance unless an alternate departure procedure (SID or radar vector) has been specifically assigned by ATC."
If a heading is assigned during the take off clearance is that a radar vector? What if the tower does not have radar?
What if the t/o clearance is turn left on course?
What if the ODP just says no turn before a certain altitude and you get a radar vector? Do you turn at 400agl or at the ODP altitude?
What if it says left turn fly this heading until 2400ft and the assigned heading is a greater left turn? Does this mean it is a radar vector and it is specifically assigned by ATC and I am not allowed to fly the ODP?
Sorry in advance for so many questions in one post.
