Brayco Micronic 889 is designed for use in electrical/electronic cooling of ground based and airborne closed loop systems. It offers high specific heat in comparison to other hydrocarbons, esters and silicone fluids. This product also provides the superior oxidative stability, low temperature properties and the hydrolytic stability characteristics typical of polyalphaolefin products. Brayco Micronic 889 has excellent dielectric properties and is harmless to most common metals of construction. It is compatible with (low acrylonitrile) BUNA N compounds and fluoroelastomers such as Viton.
This is nearly identical to my first pilot logbook, but with a new smooth matte black cover. This logbook checks all the boxes from student pilot through Commercial. It might just be the only logbook you’ll ever need. Fly safe!
