Hello Paul,



I agree, and although complex panels seem to attract some, I like the clean

panels. I also know that experimental - amateur built airplanes don't fall

under all the rules. But on the other hand I have heard stories where 

the DAR

sometimes is very specific (remember the whiskey compass discussion).

I hope you will have a DAR that accepts this and sees the sense of you

argument.



Regards,

    Maarten,

 Hi Maarten,



 I guess the regulation you cited explains why so many panels are 

 crowded with circuit breakers.  In their great wisdom, the FAA seems 

 to have dictated that solution.



 Fortunately, I don't think part 23 regulations apply to experimental 

 - amateur built airplanes.  This may be one of many examples of the 

 notion that the FAA regulations are overly restrictive on certified planes.



 To directly answer your question, my plans are to limit my flights to 

 Day/VFR.  I suspect I could safely conduct such flights without any 

 electrical equipment operating at all.  The only really essential 

 piece of electrical gear is the starter motor.  My Jabiru is not 

 likely to start any other way.



 Best regards,



 Paul

Hi Maarten,



I don't want to get into a regulation interpretation battle, but I 

will if I must.



As I understand the regs and DAR history, the compass issue is 

completely separate from the part 23 question.  Part 23 clearly 

doesn't apply to Experimental airplanes.  Experimental airplanes do 

require a compass.  The issue I have heard discussed is whether the 

compass must be a whiskey compass or if one of the new-fangled 

electrical devices like the one found on the Dynon EFIS is sufficient 

to meet this need.



I think the electrical compass is really satisfactory to meet the 

requirements, but some builders have run into this issue with their 

DAR and decided a cheap automotive whiskey compass was an easy way to 

get past an old fashioned DAR.



 From a strictly practical point of view, it makes sense that you 

need to be able to figure what direction you are going under all 

circumstances - including electrical failure.  The same argument 

doesn't apply to trying to trouble-shoot electrical problems while 

still in flight.



Best regards,



Paul
