Gentlemen,

please let me give you some short details.

Support:
PowerFLARM Displays are sold and supported in the US. Butterfly as a brand has nothing to do with PowerFLARM Displays and its support. The display design of course comes from us (Butterfly). The FLARM USA team answers all your questions and has good knowledge on the product.

Sounder Volume:
Yes, the sounder volume is limited. This is a design decision because of the very limited current that FLARM (mostly the classic one) delivers to external displays and because of size. Most pilots like it, in Europe we have sold quite some displays even to powered aircraft pilots with good results (way louder than in gliders).

Light-leakage:
This happens due to production variances in the display components we use. It neither affects performance nor power consumption and is absolutely normal.

Thanks for your feedback, it helps us improve our products.

Best wishes
Marc
Butterfly Avionics, Germany

I received a Butterfly external display with my US PowerFLARM core (brick). I also ordered a PowerFLARM Portable so have been able to compare the two.



The alerter volume of my Butterfly external display is much lower than the alerter volume on my portable, even when the Butterfly is a maximum and the portable is at reduced level.



My Butterfly external display also has light leaks along the entire top and bottom edges. These show up as light bars that are significantly brigher than the display itself. The portable display has no visible light leaks.



I contacted Butterfly and asked for comment as I did not wish to approach my dealer until I know whether these characteristics were typical of all production displays.



Butterfly declined to answer my questions and forwarded my enquiry to Lee Kuhlke of FLARM USA. It seems that Butterfly is taking no responsibility for displays that were exported to USA. Lee has so far declined to provide any answer.



So, if you have a Butterfly external display, will you please let me it it has light leaks, and also if the alerter volume is similar to, or significantly lower than, the portable.



Photos of the light leaks available by email.



thanks,



Andy.
