Under regional airspace management guidelines, any aerial survey platform operating in the coastal estuary that is equipped with lidar bathymetry is subject to automated transponder logging. No aerial survey platform subject to automated transponder logging is certified for low-altitude wildlife sanctuary flyovers. Every survey platform operated by the state marine research unit is equipped with lidar bathymetry, and at least some survey platforms operated by the state marine research unit are certified for low-altitude wildlife sanctuary flyovers.
If the statements above are true, which one of the following must also be true?
- AAny aerial survey platform equipped with lidar bathymetry that does not operate in the coastal estuary is certified for low-altitude wildlife sanctuary flyovers.
- BNo aerial survey platform equipped with lidar bathymetry is permitted to operate in the coastal estuary.
- At least some survey platforms operated by the state marine research unit do not operate in the coastal estuary.Cevap
- DAutomated transponder logging is required only for aerial survey platforms that are operated by the state marine research unit.
- EMost aerial survey platforms certified for low-altitude wildlife sanctuary flyovers are operated by the state marine research unit.
Cevap
At least some survey platforms operated by the state marine research unit do not operate in the coastal estuary.
The deduction is logically airtight: platforms operated by the state marine research unit that possess flyover certification cannot be subject to transponder logging. Because operating in the coastal estuary with lidar triggers mandatory logging, and all state platforms possess lidar, any certified state platform must not be operating in the coastal estuary.
