Another analogy for wannabes to consider of airline work once airborne.
Your mother wants you to sit in front of the washing machine which has been set to program (xx).
You have the book of instructions which details the various timings of the washing cycles for the program.
Your mission, if you choose to accept it Jim, is to watch the machine performance to ensure that “it does what it says on the tin”.
Exciting stuff?
How often has the washing machine broken down whilst operating ?
Once in a blue moon probably?
Get the picture...............?
