Hugo recently learnt how to use big ears and speed bar when flying with Reuben. His questions was: Last flight day I learned Big Ears and Speed bar, this means that I can used these now when I want to or I should do only when the instructor tell me to do ?
Like, Will be ok get close to the ridge get some high and do Big Ears or use the speed bar to training or I should wait the instructor call or I should use it only when I really need ?
Is better be High or is better be Low ?
I was thinking about Big Ears + speed-bar. I understood the speed-bar increase speed decreasing angle of attack and the Big Ears we sink faster because we decrease the lift (wing area).
Both together make sense to me, Big Ears reduce lift (wing area) but introduce more drag, decreasing speed, with the speed-bar I increase speed reducing angle of attack. When you start to go down the wind is less strong (gradient) and you go faster upwind.
Only speed-bar make sense as well, the wind increase and I want get off the ridge or I am in a sink area and I want to cross it faster.
Is there a scenario where I should use only Big Ears ? Or the "normal" is always Big Ears with speed bar ?
