Narrative:

Iad plate 20-9B improperly labels a number of the 'a' gates; specifically reversing the location of gates A4 a-c and A4 d-f (the a-c gates are located on the east side of the ramp). It also shows gate A2C as being on the west side of the 'finger;' while that gate is located directly south of the terminal extension.
