Writing to and reading from the vehicle

UPLOAD writes the plan to the vehicle

After the upload, the map goes back to panning. Thus an accidental click does not change the plan.

If the plan has at least 1 item, press UPLOAD. The solid line of the mission on the vehicle is the same as the dashed plan. The map is back to panning.

See it in Planning a hand-launched circuit, Surveying a field, From plan to flight.

Given the plan has at least 1 item
When the operator uploads the plan
Then the vehicle mission is up to date
  And the map tool is pan

UPLOAD does not send an empty plan

If the plan has 0 items, press UPLOAD. The solid line of the mission on the vehicle does not change.

Given the plan has 0 items
When the operator uploads the plan
Then the vehicle mission stays the same

Changing the plan makes the vehicle's copy out of date

If the vehicle mission is up to date and the map tool is PLAN, click the map. The dashed plan and the solid line of the mission on the vehicle are different.

Given the vehicle mission is up to date
  And the map tool is PLAN
When the operator clicks the map
Then the vehicle mission is out of date

DOWNLOAD only reads

Press DOWNLOAD. The solid line of the mission on the vehicle does not change. The dashed plan and the count on UPLOAD do not change.

When the operator downloads the vehicle's mission
Then the vehicle mission stays the same
  And the plan stays the same

EDIT brings the vehicle's mission back into the plan
