Atti vs P-Atti mode

[Hugh-1]

Sometimes while having everything powered up but just sitting on the table the mode with change from P-GPS to P-Opti or P-Atti. I understand what this is doing. There is also the Atti mode that can be selected with the switch if multiple flight modes are selected in the app. What is the difference in these two Atti modes?

Both are ATTI. The only difference is that your Phantom will automatically switch from P-ATTI to P-GPS when 6+ satellites are available again. When in ATTI mode, your Phantom will be in ATTI mode until you move the PAF switch back to the "P" position.

It's explained pretty well here:

The difference is that the Atti (F position) will not use the VPS where the P-OPTI will use it, if enabled.
