Ever got your DJI Mavic into OPTI mode and had no idea what it was?
Even worse is if you get into ATTI mode and crash your drone into the wall, but that is another story.
Let's take a look at what OPTI mode is. How it works. When you would use it. And how to not crash your drone indoors, or even outdoors at night!
OPTI mode is when the Mavic Pro is ONLY using it's vision system (forward facing and downward facing sensors) to stabilize it's position.
Normally, the Mavic would prefer to be outside with full GPS coverage and uses that for stabilization (you know how it hovers and almost does not move - that is GPS working for you).
But, when GPS is not available (too much cover, inside a building) the Mavic will enter either OPTI or ATTI mode.
This is a bit tricky to answer because "technically" you cannot control ATTI or OPTI mode.
They are only available/appearing when the GPS is not available. This usually happens when you are indoors.
So, if you are planning on flying indoors, your aim is to get into OPTI mode. But it may switch to GPS if it regains the signal.
As I said, it's tricky.
If you want to fly in a stabile manner indoors your best bet is OPTI mode.
In Opti mode the Mavic Pro will normally maintain a stabile position:
When you are indoors the optical sensors can often fail.
A quick example of someone flying indoors in OPTI mode
The Mavic has two forward facing optical sensors and two downward facing optical sensors (as well as ultrasonic sensors).
The vision (optical) sensors have a few limitations though, which are good to know if you plan to fly indoors (to avoid them failing and you entering ATTI mode).
As you can see, there are a lot of situations that cause the Mavic vision sensors to fail.
After having flown my Mavic at night, in a tight space, while trying to impress friends, I can honestly say it's not a great idea.
I followed that up by flying in the dark outside and had the same problem - ATTI Mode. (Vision sensors disabled) and then a crash!!! Albeit a small one.
Instead of making the same mistakes I did..
If you plan on flying indoors I recommend you do the following:
I have not personally tried these since my accident, but if you do - I would love to hear how you get on.
I prefer to fly outside in GPS mode :>
