Last week's question:
What switches are normally left in OFF
for normal operation?
ANSWER:
Instrument Source Selector Switches
The above picture displays the visual when the switches are "OFF"-- a normal condition and how we fly. In the OFF position, the system provides automatic instrument source selector switching in the event of a failure. Now, if you were to turn the switches on (as depicted below) the automatic switching would not occur. Therefore, we leave these switches in the OFF position.
Trivia Challenge 3
In that the last two questions have gone unanswered
This is a super easy question:
Boeing identified the Flight Control Modes of Operation as"
- Normal
- Secondary
- Direct
However, they identified the Flap/Slat Modes of Operation as:
- Primary
- Secondary
- Alternate
The question is, why did Boeing keep the same terminology "Secondary" for both the Flight Control and Flap/Slat modes, but changed the terminology for the other modes?
Good Luck!
Enjoy the Journey!
