Understand Convection : the Thermal Lift [Comprendre les ascendances]

Glider pilots use different types of lift. Today we will discover one of them : The thermal lift The Earth’s surface is far from being the same everywhere It is composed of forests fields cities lakes or other types of surfaces that do not react the same to sunlight. On a sunny day these diversities will be the origin of zones of relatively warm and cold air Warm air being lighter than cold air will rise up and generate what

Soaring Pewsey Downs and thermaling away (White Horse)

Here is this ridge. (Not very impresive, isn’t it?) I hope wind is strong enough. Because I am going down low on ridge… Perhaps I should slow down a bit, because I am not sure if I can get there This slope is too gentle to give any sensible lift Only next part loos sensible. I am so damn low now… I’d like to get a thermal now… …so I could safely get to the higher part of the ridge.

Understand Wave Flying [Comprendre le vol d’onde]

In this episode, we will make you feel and understand the basics of wave flying which is another phenomenon that associated to wind Wave flying is a dynamical lift phenomenon occuring in mountain areas when the wind blows It enables glider pilots to reach high altitudes in the atmosphere and fly thousands of kilometers in one flight When the wind blows over an obstacle, generally a mountain the airflow is disturbed from its initial trajectory If the air mass is

Sky Full of Heat – New book by Sebastian Kawa

SKY FULL OF HEAT New Book by Sebastian Kawa Promotion party For quite a while I have been thinking about writing a book about gliding as there seems to be a demand for such publications. The publisher, Sławek Piela approached me but he had a slightly different idea. I wanted to write a ‘technical’ part, how to use lift, ridge, wave etc. He wanted a book aimed at wider audience, not only for pilots. He wanted a book that would

Understand Ridge Soaring [Comprendre le vol de pente]

In the previous episode we have talked about the thermal lift We know that the origins of thermals are linked to contrast of temperature. Nevertheless, when it comes to mountains, glider pilots can also use phenomenons associated to wind. Let’s talk about one of them : ridge soaring Ridge soaring is really simple to understand When the wind blows over mountain it tends to be deflected upwards Generating a zone of rising air directly above the slope Glider pilots just

Riskantes Fliegen?! | Low and Slow | FPV Reality in Bosnia

Hey guys! Today I will talk about a more serious topic I got lots of comments and also private messages from friends who think that my last video and perhaps also other videos are not appropriate to upload on YouTube and it is hazardous flying. Yes, it´s true that the last video which I uploaded from the GP in Bosnia That was really hard flying on the ridge without lots of speed reserve and height There must be everything perfect,
