This document shows the various ways the Flytec instrument
displays Vario and McCready (“MC”) Speed-to-fly “STF” information and also
describes the MC audio function. This document expands on Sections 4.10, 10.4,
10.5, 10.6 of the Flytec 5030 manual v 2.24 (and the similar, I presume,
sections of the 6030 manual).
