SharePoint Online Calculated Formula – SharePoint Stack Exchange

I am trying to create a formula that will auto-populate a column based on the input from two other columns. The auto population would need to check the boxes of the appropriate items that apply based on the input.

Example-
Column A-Flight Type:
Orientation
Spouse
Private

Column B- Aircraft type:
Airbus 100
Airbus 200
Airbus 300

Depending on the selection of a and b I would like c to auto-populate required tasks from 10 choices
