|Firmware changes are required for:
● Blade leading edges NOT facing forward.
● Stall Tip Blades
● Direct Drive Turbines
● Obstacles in the vicinity that are taller than 15 meters. (trees, power lines, etc.)

1. Attempt to relocate the takeoff location to the blue region and try again.
2. If the model does not match after three attempts, contact Tech Support with pictures of the nacelle, the base of the tower, and surrounding obstacles.

There may be too much “noise'' in the lidar data to distinguish the turbine. This may be the result of obstructions near the ground. tall trees firmware modifier may be necessary. It may also indicate a poor scan caused by a bad takeoff position or faulty lidar.

● Aircraft does not move to first
|The system will sometimes plan
waypoints that are too far away or
unsafe to reach.
This is especially true for:
- partial inspections.
- close proximity turbines.
- offshore operations.
- avoid Sun feature.
1. Power on the drone as close as possible
5. Attempt to yaw the turbine or come back at a later time to avoid interference from the sun.

|If the camera and gimbal are active, this is the result of the takeoff climb being too close to the turbine. It is likely that the aircraft actively avoided
the turbine during the climb.
| 1. Confirm that the camera and gimbal
are being reported as active.
2. On the next flight, adjust climb
position to a safer distance and try

Rotor, especially on low/no wind days.
The best approach may be to use “Big tower method”, with a climb in the red dot area, and the drone yawed slightly away from the tower.
(Flip for the left side.)
The key is to align the GPS arms just outside the blade tip and nose cone, similar to the orange line. This allows the drone a decent amount of exposure to the trailing edge of the suction side, helping to eliminate the framing issues you're seeing, while also giving it a more "squared on" view of that blade tip way down there. There may be some trial and error to find your particular sweet spot.
|11 of 12 sides may be flown. Just remove the
trailing edge of the down blade from the
inspection blade setup list on the GCS.
2.8. Common Reasons for Re-Flies
The following examples are typical reasons why a re-fly of a turbine might be necessary
1. Blurry Images
a. Ensure that the camera lens is clean before each flight.
b. Use a landing pad to prevent dust from being kicked up during takeoff.
c. Be aware that moisture can condense on equipment, especially during the first flights on cold
2. Missing Tips
a. Ensure that the GPS arms are parallel to the plane of the blades, only slightly angled toward
the tower, if at all. If the aircraft is angled too much then the antennas can block the LIDAR
from seeing the tip of the blade.
3. Missing Edges
a. Ensure that the proper modifier is in use, clean vs te-out can cause this.
b. Adjust takeoff position to the side to give the LIDAR a better view of the side of the up blade.
This is how the system determines the max chord length of the blade and determines proper
photo waypoint position.
4. General Framing Issues
i. Ensure that the camera is straight on the gimbal and securely mounted.
ii. Ensure that the gimbal is mounted straight on the SR.
iii. Ensure that the SR is mounted straight on the Alta and secure so that it cannot rotate.
i. Inspect the GPS assembly and perform the GPS care procedure as necessary.
Specifically check that both GPS antenna arms are secure and properly oriented
ii. Wait 5 minutes between convergence and takeoff to avoid GPS shifts in flight.
i. Ensure that the LIDAR remains clean throughout the day.
ii. Ensure that the LIDAR is securely mounted to the top of the SR and cannot rotate or
wobble. Check the 2 pins which pass through the top plate of the SR into the LIDAR to
secure it in the proper orientation. Re-secure the pins and LIDAR screw as
d. Takeoff Position
i. Use the Big Tower Method as appropriate, especially for turbines over 110 m rotor
ii. While the Sweet Spot is a good rule of thumb for most turbines, certain turbine models
require a very specific take off position for successful framing.
