Hi there,

I'm getting ready to do my practical flight test to get my CAA qualification, one of the things we're tested on is using "ATTI" mode, which from what I understand is like GPS only it doesn't counteract wind movement...?

But what is "ATTI" mode called on a 3DR Solo? I can't find it on the drone.

I'd really appreciate any help.

Thanks guys!

Manual Fly mode......maintains altitude but not drift. It DOES not use GPS. Is this a DJI test or what?

James,

In Solo, I believe ATTI mode would be equivalent to Manual Mode. Here are the various Solo flight modes.

Manual
Fly:Manual mode is a version of standard flight without GPS lock. In Fly:Manual, the throttle stick controls altitude the same way as standard flight (Fly mode). However, Fly:Manual includes no GPS positioning so that, when you release the right stick, Solo will not hold its position; it will drift according to wind conditions and existing momentum. When flying in Fly:Manual, make constant adjustment to the right stick to control Solo’s position and use the left stick to maintain Solo’s orientation.

Stabilize
Stabilize mode provides full manual control without autopilot assistance. In stabilize, the autopilot regulates Solo’s roll and pitch angles so that Solo returns to level when you release the right stick. The throttle stick controls power and acceleration directly; it does not correspond to altitude. Stabilize requires fine-tuned control of both the left and right sticks to fly Solo. Stabilize does not require GPS lock.

Drift
Drift modes requires GPS lock and provides a plane-like flying experience. Drift is ideal for navigating Solo using the video feed. This is known as first-person view (FPV) and provides an immersive flying experience. In drift, Solo combines roll, pitch, and yaw onto the controller’s right stick. To navigate Solo in drift, move the right stick to initiate a coordinated turn in that direction. Releasing the right stick will cause Solo to drift to a stop over a two-second period. Solo does not automatically control altitude in drift, and will require constant adjustments to the throttle stick when flying in drift.

Acro
Acro is the most advanced of Solo’s flight modes. It provides unrestricted control over Solo’s roll and pitch angles. Acro is intended for performing aerial acrobatics, flips, and maneuvers requiring extreme angles. There is no altitude or position assistance in acro, so be prepared to make constant adjustment to both sticks. Acro is a copter-frame oriented mode, meaning that, in acro, Solo will always respond to controls relative to its own orientation. Acro does not require GPS lock.
Advanced flight modes are for experienced operators only. Do not attempt to fly in any advanced modes unless you are comfortable flying multicopters without positioning and altitude assistance.
Do not fly in acro unless you are an extremely experienced operator. Without the proper skills, crashes in acro are highly likely.

Sport
Sport mode in a modified version of acro that includes altitude assistance and earth-frame orientation. With altitude assistance, the throttle stick behaves the same in sport as it does in standard flight (Fly mode). Earth-frame orientation differs from copter-frame orientation in that the direction of yaw rotation is in relation to the earth instead of in relation to the copter itself. For example, if Solo is pitched forward in sport mode and left yaw is applied, Solo will maintain the same pitch angle and rotate around the vertical axis. As opposed to in acro’s copter-frame orientation, in which, in the same situation, Solo will perform a cartwheel. Sport does not require GPS lock.

Haha yeah they all seem to be using Phantom's, that's why they chose that working obviously, you can see why I was a little confused!

ATTI is short for Attitude (as in maintain your attitude relative to the stick position), which is just stabilization (keep it level using gyros and accels), no gps or barometer. This is called STABILIZE in Solo-land.

It is not "manual" -- manual uses no gps but uses baro. IMHO this is a bad name for what it is, because it's less manual than attitude mode. Before solo, FLY: Manual had a better name: Altitude Hold (as in use also the barometer). FLY was named "Loiter" (as in use the barometer AND GPS).

it used to be basically this, in order of increasing number of sensors used):
Acro (ACRO, use gyros only)
Attitude (STABILIZE, use gyros and accelerometers)
Altitude Hold (FLY:Manual, use gyros, accels, baro)
Position Hold (no Solo equiv, use gyros, accels, GPS)
Loiter (FLY, use gyros, accels, baro, GPS)

James,

Sorry for the mis-information. I believe Z-axis is correct.

"ATTI is short for Attitude (as in maintain your attitude relative to the stick position), which is just stabilization (keep it level using gyros and accels), no gps or barometer. This is called STABILIZE in Solo-land."

Thanks for the correction Z.
