Green Dot F and S speed...

[m39462]

The flap/slat settings are 0,1,2,3 and Full so why not refer to and display the speeds using the same numbers?.

Because 1 and 2 at least are already in use to bug V1 and V2?

So you think

The autothrust does not "control" the speed

I disagree.

You might want to read your FCOM again.

Here is a direct quote from the FCOM, DSC-22-30 Auto flight - Flight Guidance - Autothrust - general:

The autothrust system, when active:

‐ Controls the aircraft speed or Mach in SPEED/MACH mode

In your own words:

... a thorough understanding of how the automation systems work and interact is important.

We're splitting hairs here gentlemen...
