In enroute delay notation ABY/D00+20, what does DHH+MM indicate?

In enroute delay notation ABY/D00+20, what does DHH+MM indicate?

• A. Delay Hours and Minutes
• B. Airport Identifier
• C. Day Hours
• D. Delay Hours and Minutes with a different format

Answer: (A)

In enroute delay notation, the DHH+MM portion shows the amount of delay in hours and minutes. The D signals Delay; HH is the two-digit hours; the plus sign is just a separator; MM is the two-digit minutes. So D00+20 means zero hours and twenty minutes of delay at the listed location (ABY). This is why the correct interpretation is Delay Hours and Minutes. The other options don’t fit because the location code ABY is the airport identifier, not part of the delay duration, and Day Hours isn’t a recognized metric in this format.
