variometer

Two variometer stations were recently established--Polom (PLM) in Eastern Bohemia at the Czech-Polish border and Kelcany (KEL) in south Moravia--see Figure 1.

For correction of measurement results and for records of temporal variations of the geomagnetic field is necessary to install variometer station on territory of Latvia, because some repeat stations are located further than 500 km from Toravere (Estonia) Observatory variometer station.

Paul MacCready (then a student at Cal Tech) developed the idea of a rotating velocity bezel (or "speed ring") for the variometer of a glider which tells the pilot at just what speeds to fly for optimizing the glide ratio through rising or sinking air.

Mr Bullock told the inquest that Mr Mousley's glider had a faulty audio 'variometer' - an instrument which measures the rate of climb and descent by emitting sounds.

"We also use a variometer which tells you whether you are going up or down.

The S6RT we flew was equipped with a Dvnon 10A EFIS and an LXnav LX8000 color navigation and variometer system (sailplanes use a more sensitive vertical speed indicator, called a variometer or "vario").

For those who wish to build their own magnetic storm detector, there are two popular designs--the variometer and the fluxgate --which are sensitive enough to detect storm-induced changes in the Earth's magnetic field, and technologically within reach of the amateur observer.

They also have a variometer -- to detect rates of ascent or descent -- on board, the source added.

But there is one instrument you'll find in the sailplane's panel that won't be in the typical Skyhawk: a variometer. This is analgous to a vertical speed indicator, but is more sensitive.

The version we flew in Florida in April didn't even have a radio, but basic instrumentation including a digital variometer, an airspeed indicator and an altimeter, plus the engine gauges.
