This is the story of owning and operating a 1993 Beech Bonanza A36 in the UK and some of its adventures and flights. I have owned this plane for nearly six years now.
I recently purchased a Zaon XRX passive traffic monitor box
to use in the Bonanza. Having owned a previous version of this companies products that was totally rubbish I was very nervous of what I would find and waited much longer to buy one than I would have as they have been out for at least three years I think.
I was however pleasantly surprised at how effective this box is. Whilst you do get the odd false positive (twice from behind a contact appeared on the device and collided with me but I never felt the bump!) but the box regularly spotted planes that it took me a little while to make eye contact with. In fact sometimes I couldnt see them when the Zaon could.
They do say on their website that accuracy from behind is most troublesome in some planes and I would suspect that the Bonanza A36 is a candidate for causing trouble having no rear window. I do eventually intend to fit a full glass cockpit and proper TCAS but in the meantime I strongly recommend this device. They are tiny and dont cost that much and just could save your life.
