### ❗ Guideline for asking a Question

1. Specify what you are trying to **achieve**
2. Specify what environment / **platform** you are using
3. Prepare a **Link** or **Document** to help understand if possible
4. First, ask the question on the **Slack** or [create a **Github Issue**](https://github.com/PX4/PX4-Autopilot/issues/new/choose)!
5. If you take over 5 minutes for the question, please continue in Slack or a Github Issue.

### Q.1 : Issues while testing beta v1.13 blocking Fixed Wing Test Flights - Jakob

1. Airspeed Sensor not calibrating  
[13.0rc1 airspeed calibration not possible · Issue #19772 · PX4/PX4-Autopilot · GitHub](https://github.com/PX4/PX4-Autopilot/issues/19772)

2. Servo direction not working in stabilized mode

> 13.0xx testing. Hi Would be interested to hear how many fixed wing users do testing. I experience issues with rc1. (i.e airspeed, servo direction in stabilized mode if orientation of pixhawk is not default. Quite a big number of parameter do not get set to the default value even after a full parameter reset. I have not seen this from 1.11 to 1.12 ( I am testing on holybro 4 and 4 mini)

- Feedback: On current master branch it seems to work - Ryan
- Fixed Wing with Control Allocation works - Silvan
