Using a paragliding GPS Alti-Variometer : how to use the flying device ?

use of gps alti variometers for paragliding

Experienced paragliders know how essential it is to have the right instruments to fly safely and make the most of their experience in the air. Among the crucial pieces of equipment, the GPS alti vario stands out as a multifunctional tool that provides essential information for every paragliding flight. In this article, we'll explore in depth how to use a GPS alti vario for paragliding, highlighting the features, necessary settings, and vital information it can provide.

HOW TO SET UP YOUR PARAGLIDING ALTI VARIOMETERS GPS ? 

When you own a GPS alti variometers, it's important to understand how to set it up so that it's effective throughout your flight, from take-off to landing. Here are some essential steps for setting up your GPS alti vario :

  • Choosing your GPS alti vario : Before you start, make sure you have the right GPS alti vario for your paragliding needs. Top brands such as Syride, Flymaster and others offer a range of options at a variety of prices.

  • Installation and start-up : When you receive your alti vario GPS, read the user manual carefully to learn how to set it up. Generally, this involves charging the battery, switching on the device, following the instructions, updating the software etc...

  • Setting departure altitude : Before each flight, you need to set the departure altitude on your GPS alti vario. This will enable the device to accurately calculate your current altitude relative to the starting point.

  • Setting alarms : You can set alarms on your GPS alti vario to warn you when you're approaching restricted airspace.
  • Unit configuration : Make sure that the units of measurement (meters or feet) are correctly configured according to your preferences. Similarly, check that vertical speed units (m/s or ft/min) are also set as you wish.

  • Instrument calibration : From time to time, it may be necessary to calibrate the GPS alti vario in flight to ensure maximum accuracy. Simply follow the manufacturer's instructions for this operation.

  • GPS synchronization : If your GPS alti vario has a GPS function, make sure that it is correctly synchronized and that GPS signals are available before takeoff.

  • Data check : Before you take off, check that all essential data, such as altitude, vertical speed and ground speed, are correctly displayed on the screen.

Once you've made these basic settings, your alti-variometers-GPS is ready for use during your paragliding flight. It's important to note that exact instructions may vary depending on the make and model of your device, so be sure to consult the manual specific to your instrument.

WHAT DATA IS IMPORTANT TO VIEW ON YOUR PARAGLIDING ALTI VARIOMETERS ?

A paragliding GPS alti variometers can provide a wealth of information, but it's essential to know which data is most relevant to your flight. Here are some of the important data you should keep an eye on during your paragliding flight :

  • Altitude : Current altitude is one of the most crucial pieces of data for a paraglider pilot. It tells you how high above sea level you are, or how high above take-off you are, depending on the data you need.

  • Vertical speed : Vertical speed, measured in meters per second (m/s) or feet per minute (ft/min), shows you how fast you're going up or down. This usually helps you to roll up thermals or escape an area of steep descent.

  • Ground speed : Ground speed, measured in kilometers per hour (km/h) or miles per hour (mph), tells you how fast you're moving horizontally. It's particularly important when you're flying in a windy air mass.

  • GPS position : GPS coordinates give your exact latitude and longitude location. This can be particularly useful for navigation and for marking landmarks throughout your flight.
  • Altitude alarms : Pre-configured altitude alarms warn you when you reach specific altitudes. This is very useful for making informed decisions in good time.

  • Battery life : Be sure to monitor the battery life of your alti vario GPS to avoid battery depletion in flight. To prevent premature battery wear, refer to your brand's manual.

  • Wind speed and direction : GPS vario altimeters display wind data in real time. However, this data is calculated from your drift in the thermal, so it's not 100% reliable. In addition, wind strength and direction vary greatly depending on your position in the air mass and your movements.

CAN YOU FLY WITHOUT A PARAGLIDING ALTI VARIOMETERS ?

Although the GPS alti variometers is an invaluable tool for paraglider pilots, it's important to note that its use is not strictly mandatory for flying. In fact, it's highly recommended that beginners fly without one, so as to be able to make the most of the air mass before using a flight instrument.
