During a winter operations evaluation at a northern military airfield, ground safety protocol mandates that whenever runway friction coefficients drop below 0.35, flight operations must immediately suspend all incoming heavy transport landings and dispatch maintenance crews to spray chemical de-icing fluid. During a sudden freezing drizzle event, continuous telemetry reports indicate that the primary runway's friction coefficient has fallen from 0.42 to 0.28, while several scheduled cargo transports are currently on final approach.
Based on the passage, what action will the airfield operations team most likely take next?
- APermit the approaching cargo transports to complete landing before the freezing drizzle worsens.
- Suspend the landings of incoming cargo transports and begin spraying chemical de-icing fluid on the primary runway.Cevap
- CDispatch mechanical wire plows to scrape ice off the runway surface rather than using chemical agents.
- DWithhold all landings until friction measurements climb back to the baseline reading of 0.42.
Cevap
Suspend the landings of incoming cargo transports and begin spraying chemical de-icing fluid on the primary runway.
The passage outlines a clear cause-and-effect standard: if runway friction falls below 0.35, heavy landings must be suspended and chemical de-icer sprayed. Because the measured value is 0.28 during the freezing drizzle, the operations team will follow protocol by suspending incoming cargo landings and deploying chemical de-icing fluid.
