At software release 10.3.0.2, the IFD has the capability to display dual engine flow as long as the interfaced fuel flow monitor is capable of sending dual engine fuel flow information. To set up the IFD for Dual Engine Fuel Flow information you will need to access maintenance mode on the IFD. Steps for accessing maintenance mode can be found in the pilot guide (page 7-56 in the IFD 5XX Pilot Guide and page 6-53 in the IFD 4XX Pilot Guide). If you do not have a IFD Pilot guide, one can be downloaded at the link below:
Once in maintenance mode, follow the directions below:
In order to receive multi-engine fuel flow, the fuel reporting device will also need to be configured. Without this device being configured, the IFD may not display any fuel flow at all or display only data for one engine. The applicable installation manual should be referenced for the installed fuel flow indicator. This procedure should also be done by an appropriately certified technician. Below is an example of instructions for the Shadin DigiFlo:
If fuel flow is not present after configuring both devices, the system should be analyzed by a certified technician to ensure configurations were administered properly. The technician will contact Avidyne technical support should any problems be discovered that the technician is unsure of. Avidyne technical support will direct you to your local Avidyne Dealer to have the interface checked for proper configuration if contacted before having a technician review the system and configuration.
