I am a low-time pilot, of approximately 200 hours. I trained on the DA20 and DA40, designs that are derived from the Diamond touring motor glider design(s) of the early 1990s. I anticipate getting my Glider rating this summer in the US. As I've considered getting my glider rating, I've noticed a habit that I've developed that closely matches the "glider pilot mentality" which does not seem so prevalent in my training for ASEL.
I've always preferred using a forward-slip for landing with the engine idle, as opposed to using the throttle to adjust the descent angle. I attribute this to multiple factors, such as being aware of the design history of the DA20, training with its more "glider-like" characteristics, and a general paranoia of the engine quitting on base or final.
This brings me to the following questions: What are the safety considerations for this type of approach? Are there limitations on the use of sideslip on light airplanes?
Edit: Supplement questions, for possible merge or replacement of above. (Taken from my comment below)
- Instead of puttering in using throttle, why don't we use side slips all the time?
- Why don't most/more GA aircraft have spoilers or dive brakes?
- Is the mentality of "every landing is an engine-out landing" creating more danger than it alleviates?
