Good morning,
Quite confusing!
1) A/THR will manage F/S/O speeds as speed constraints where we don't have to level-off isn't it? So is there a F/S/O point in our F-PLN? If, not how does it know when to manage these speeds? Does it manage F/S/O in selective mode? Because there can be waypoints between F/O/S with speed restrictions too.
Ok, so you activate approach speed, then only it will display the amber =.
The plane will go down to green dot, around 210kts. But the amber = will come at 230kts.
So you can retract flaps below 230kts. When you are at 1, you will see that S speed is around 180kts but the amber = is at 200kts. The plane will go towards S speed. 180kts is a comfortable to fly with flaps 1 but we can go to 2 below 200kts, so once passed the amber =. When you are at flaps 2, you will see F speed around 140kts. Then, you will see that the amber = is at 185kts. When below 185kts, flaps 3. F speed is a comfortable speed to fly with flaps. Finally, you will see the amber = at 177kt, you can then have flaps full. But you can simply fly with flaps 3 at Fspeed (140kts).
2) Is everything right?
3) Is F speed a comfortable speed for flaps 2 or flaps 3??
4) Do you only see the next amber = when you extend of 1?
Thanks
