What special training is required to fly in the Washington DC area? I remember hearing that special training was required to fly into the Washington DC area and that it didn't really apply to me (maybe it was VFR only?).  What is the requirement and what must you do when flying in the area?
There is a training course on FAASafety.gov that all pilots operating VFR flight within 60nmi of Washington DC must take.

Since I assume you are flying IFR, you would not be required to take it.

From AOPA:


  All of the following operations are exempt from the training
  requirement:
  
  
  Pilots operating under instrument flight rules (IFR);
  Law enforcement, military, and aeromedical operations; and
  A pilot who must deviate to the extent necessary to address an emergency situation.
