What emergency is described when the pilot continues the prebriefed departure using dead reckoning to maintain the arc until the assigned departure radial is reached, then continues to climb to the emergency marshal altitude, reverse course, hold overhead, and commence at EEAT with Emergency BRC?

The scenario is testing how to handle an emergency when you lose communications and a key navigation aid (DME) in instrument meteorological conditions. With DME out, you can’t rely on distance to a VOR/DME, so you navigate by dead reckoning and published routing instead of radio guidance or DME distances. The described actions—continuing the prebriefed departure by dead reckoning to stay on the arc until you intercept the assigned departure radial, then climbing to an emergency altitude for obstacle clearance, reversing course, holding overhead, and rejoining at the expected altitude with an emergency clearance—fit exactly a loss of comms plus DME during IMC. This sequence shows how you maintain a known path and preserve safety even when a primary distance navigation aid and two-way radio are unavailable.
