Or is that stating the bleeding obvious?
I don’t believe the performance is compromised at all. The performance is based upon a requirement for short range air/air detection and conspicuity in accordance with a technical specification detailed in CAP 1391. The product achieves this. Surely it would only be ‘compromised’ if it didn’t achieve the requirement?
That is what you said @Cub in response to @Crash one saying the performance of SE2 is a compromise to allow it to fit in a small box with internal power.
"The performance is based on a requirement... ...in CAP1391". But there is no performance requirement in CAP1391 - lots of other technical requirements, yes.
So clearly you agree that it is perfectly possible for PAW to do what it does better than SE2, in a performance sense.
I am not critical of SE2 at all. It meets a requirement for EC and is very convenient. It's designers have done a good job. But they chose to make different compromises to the designers of PAW.
And, as pointed out before, we have no test data on either in terms of their performance. I totally discount the vector diagrams and the anecdotal review of the Flyer article - they just aren't technically sound.
I think you are comparing apples and pears. I am talking about the performance of an EC device designed to achieve short range air/air electronic conspicuity and detection, built in accordance with a technical specification published by an aviation regulator. PAW clearly may do other things better or worse against another set of requirements but most definitely is not compliant with CAP 1391. Clearly two very different products.
I think most GA pilots reading the pros and cons of each device will come to the correct choice for their situation despite no clear reiteration of policy or guidance from the CAA. My personal hope remains that people prioritise making themselves electronically conspicuous via ADS-B Out and then assess their further requirements and the merits of the various devices available.
