Hello,
I'm b737 FO and I have some questions about coupled app.
Q1. As far as I know, coupled App is the Instrument App performed by A/P regardless of 2nd A/P engagement. Is it correct?

Q2. What's the difference between coupled app and auto coupled app? I am also confused about APFD and coupled App.

Best regards,

Approach can be coupled to FD only, which you manually fly or coupled to AP which is flown automatically by the AP. Second AP is for ILS approach only.
