Nuckolls, III" Subject: Re: AeroElectric-List: RV-14 Having the engine monitor operational during start is 'nice' and seems like a must, but for me the brownout problem was for the rest of the EFIS function - flight plans and such - along with the engine monitor display. I had this brownout problem with a dual alternator -dual batt Z-14 on my RV10. > Brownout resets are not an architecture problem, > they're a radio problem.

I don't care if the 'radio' gracefully recovers or not from a brownout at start. Too specific on my part . . . sorry. It's an electro-whizzy. In particular, one that stores data in non-volatile memory and/or takes a non-trivial interval to wake-up after power-ON. In my case, little/no risk if devices are allowed to fully boot or re-boot. Having them re-boot during the boot process can make them sick. I'm not worried about the oil pressure either. Not sure what you mean by 'sick' . . . other than loss of data that could/should be in flash as opposed to ram.

I knew what you meant but maybe would should stick to proper technical terms like 'whizzy' and 'kitchen sink' going forward. > In my case, little/no risk if devices are allowed to fully boot or > re-boot.

Design deficiencies not withstanding "booting up" is not a stressful activity. I am reminded of an oft proffered diagnosis by the warranty service tech praying over a slightly smoked radio, "I guess a spike got it."
