Conversation

1. Does a controller see clutter on his radar scope? Do mountains cause clutter on a radar scope? Buildings? Clouds? An aircraft? What is clutter? Can clutter move? Is it easy to see the target with clutter? What type of radar has clutter?

2. Can a controller switch off clutter? With MTI can he switch off stationary clutter? Fixed clutter? With what does he switch off stationary clutter?

3. Can a controller switch off clutter caused by moving objects with CircularPolarization? Stationary objects? What can he switch off with Circular Polarization? Can he switch off the moving target with Circular Polarization? What does he switch off with Circular Polarization?

4. Are hazardous conditions dangerous? Are low clouds around an airport hazardous? Obstructions on the runway? Passengers smoking at take-off? A meal from the galley? What do you consider hazardous in aviation?

5. Is automaticdataprocessing a modern invention? Do we use automatic data processing in aviation? In other fields? Did Marconi (the inventor) have automatic data processing? Who uses automatic data processing?

6. Does a controller have flexibility with Circular Polarization and MTI? Does this flexibility permit him to use Circular Polarization and MTI? Circular Polarization or MTI? Does this flexibility permit him to use Circular Polarization alone? Does this flexibility permit him to show only clouds? Only precipitation? Or both?

7. Are slashes another term for target? Are slashes another term for blip? Echo? Are slashes a description of a dot or a line? Are slashes seen on SSR? Primary radar? On what type of radar are slashes seen?

8. Do two aircraft on the scope appear as one slash when they overlap? Do slashes always overlap on the scope? Sometimes? Partly? Completely? Is it good that slashes overlap on the scope? Why is it necessary to separate them when they overlap?

9. Does everybody have some deficiencies in their character? Is good humour a deficiency? Good manners? What are one's deficiencies? Are there deficiencies in aviation? Can automation help to eliminate some of the deficiencies in aviation? Data processing? Computers? New inventions? Tell me some of the deficiencies inherent in radar.
