# SB\_0000003 Flight with Arming Checks Set Anything other than 1 prohibited

**For the latest updates, refer to the following link:**\
[SB\_0000003 Flight with arming checks set to anything other than 1 prohibited](https://discuss.cubepilot.org/t/sb-0000003-flight-with-arming-checks-set-to-anything-other-than-1-prohibited/857)

We are seeing too many logs where arming checks are set at either 0, or at a value other than 1.

If your vehicle will not arm, you need to investigate why! do not take off until you have solved the issue that is causing the arming checks to fail.

The arming checks are there for your safety, and the safety of those around you.

the following parameters are NOT OPTIONAL on Cube Black, Green, Blue, Yellow, Orange\
\#NOTE: CUBE\_BLACK\
BRD\_TYPE,3 #sets the board type to the three IMU board\
EK2\_IMU\_MASK,7 # makes sure that 3 EKF’s run\
INS\_USE,1 #the following three parameters enable the IMUs\
INS\_USE2,1\
INS\_USE3,1\
LOG\_DISARMED,1 #ensures you can get a log that includes pre-arm information\
ARMING\_CHECK,1 #Ensures that you run all the arming checks. Your safety comes first

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.cubepilot.org/user-guides/service-bulletins-and-critical-notices/safety-service-bulletins/sb_0000003-flight-with-arming-checks-set-anything-other-than-1-prohibited.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
