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

[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\
