How are enroute delays annotated on the Route of Flight on an 1801?

• A. Airport Identifier/DHH+MM
• B. Time/Date Stamp
• C. Route Segment Code
• D. Delay Hours and Minutes

Answer: (A)

The instruction here ties a delay directly to a specific point on the route. By presenting the airport identifier plus the delay duration in hours and minutes, you can see exactly where the slowdown is expected and how long it will last. This format makes the delay concrete and location-specific, which is essential for planning the next segments of the flight. So a notation would pair the next airport code with the delay time, written as something like the airport code followed by the hours and minutes of delay (DHH+MM). That gives both the location of the delay and its length, which is why this approach is used. Without the airport code, a time stamp alone would not indicate where the delay applies. With just a duration, you wouldn’t know where along the Route to anticipate it. Other formats don’t provide the required combination of location and duration, so they aren’t as informative for enroute planning.
