INTRODUCTION

This Service Bulletin (SB) announces the availability of Synapse Version 3.5.1 and ALTA App Version 1.2. Synapse version 3.5.1 includes safety improvements to the existing 3.4.0 firmware, and is recommended for all operators.

 

Synapse 3.5.1 removes the option to use GPS Height Correction in Height or Position modes. Freefly expects to reenable the feature in a future release.

 

 

BACKGROUND

Synapse Version 3.5.1 contains the following changes from Synapse Version 3.4.0.

  • Improves heading estimation accuracy.
  • Disallows changes to GPS Height Correction.
  • Changes default GPS Height Correction to Off.
  • Changed ESC temperature alarm from 90°C to 70°C.

 

ALTA App Version 1.2 contains the following changes from ALTA App Version 1.1:

  • Dynamically hides GPS Height Correction parameter for ALTAs with Synapse 3.4.0 installed.
  • Added Synapse Version 3.5.1

 

OPERATIONAL CHANGES

Synapse 3.5.1 does not allow the use of GPS Height Correction feature and resolves the condition noted in the GPS Height Correction Service Bulletin issued on October 10, 2015.

 

The ESC temperature alarm has been reduced in 3.5.1. If an alarm is indicated on the ALTA status light, land immediately. After landing, use the ALTA App to determine the type of alarm. In the event of an ESC overtemperature event, allow the ESC to cool before flying again.

 

METHOD OF COMPLIANCE

Synapse Version 3.5.1 is packaged in ALTA App version 1.2. Download the update to your mobile device using either Android Play for Android devices, or the App Store for iOS devices.

 

To update firmware, follow the steps in the Aircraft Flight Manual in the section Firmware Update Process.

 

After updating, reversion to Synapse Version 3.4 is also possible with the app using the same process. Reversion is typically not recommended.

 

 

KNOWN ISSUES

There are no known issues with Synapse 3.5.1, or the reversion process to Firmware 3.4.0.
