IFR departures from runways 1 and 33 at DCA are cleared to intercept and track the DCA 328 radial both for noise abatement and in order to remain clear of P-56, then expect vectors to the exit gate associated with the intended direction of flight:
North: EMI East: SWANN, PALEO South / Southeast: DAILY South / Southwest: HAFNR, FLUKY West: LDN, AML (J149) Northwest: MRB, BUFFR, JERES
What is the criteria, distance from DCA or aircraft altitude, used by ATC to determine when an aircraft is to depart the assigned 328 radial and be issued a clearance to it's respective exit gate
It has been a while since I have been there, but if I had to guess, I would imagine it is based more on distance than altitude. I believe the prohibited areas are from the surface to 18,000 feet and you are not going to out climb them before you pass them. For eastbound departures you always have to pass the Naval Observatory before you make a right turn no matter what your altitude. For westbound departures I think it was based more on altitude depending on IAD arrival and departure gates. That would be my best guess.
1) distance to clear P-56 (not really that far, you could turn right again almost right away).
2) altitude/distance reference the IAD departure gates and to sequence with other traffic to your outbound fix.
If you're climbing at 250kts there's not much you can do to hurry your turn on course. If you're still heading out the 328 radial passing through 10k' and looking for a right turn on course, then they have traffic ahead of you, and they'll turn you when they can. Just fly your aircraft/company profile so they know what to expect.
It's based on Altitude. When you get above 9,000, they can clear you for a turn towards the departure fix. You have to cross over traffic at 8000 arriving over AML/ELDEE. You are well clear of P-areas by the time you climb through 9,000.
I noticed the engine out proc has changed as well from Aerodata. It has you joining up on the 341 radial till 2.6 dme from dca vor and then turn left to a heading of 310. I just wondering how close you get to p-56 on that 341 radial?
