Multiple varios
Why do so many gliders seem to have multiple varios? Is it that critical to have a back-up for this instrument? Do they often fail and leave you in "
the lurch"? |

Feeling of inadequacy/vario envy. Folks wanting multiple things like different time constants/settings. Display of "other stuff" when the displays start being multi function displays. Alternate source, e.g. electronic comp vs TE probe Hiding ugly holes in the panel. Backup (they really don't fail often if looked after). |

John:
This is a subject on which experienced glider pilots will disagree on. Many now use electronic instruments exclusively, in which case a single good vario is the norm. Others - who have doubts about battery sustainability (especially on long flights) will want a mechanical back up. I've had batteries fail very far from home and was happy to have a mechanical vario backup. Or it may depend on your OCD medication level . . . Roy |

Span matters!
Since all gliders are built the same, you can express your personality through your panel. |

But seriously, I've always liked having a good (simple) mechanical vario backing up whatever electronic wizardry is the flavor of the month/year. I do from time-to-time like to compare readings, response rates, etc. just to make sure the morons, the neurons, and fig-newtons in the electronic instrument are behaving. In fact, I discovered a hardware/software problem this year when I started to notice consistent differences between the two instruments. In 30 years of XC gliding, I'd say I've actually had to rely on the mechanical backup maybe 3 times when the electrics went south. Not exactly a compelling reason, but we're creatures of habit.

man with two watches never knows what time it is.
and the guy with 3 or 4 varios never knows how strong the thermal is either. |

I have a mechanical vario as a second because it will get me home if I have a complete electrical failure. That and a chart is all I need to get back. And yes it has happened. UH |

I used exactly the same reasoning as Papa3, but fitted two electronic varios. The main one is entirely dependent on the main glider battery. The other normally runs off the main battery but also has a 9v PP3 strapped to its rear that can run it for 8-10 hours if the main battery fails. I do in fact glance at it for confirmation while hunting for thermals, because it has a much faster response than my main vario and I also prefer it when ridge running because, unlike my main vario, it makes 'sink' noises as well as 'climb' ones. -- Martin | martin at Gregorie | gregorie | dot org |
