Aircraft Design Tutorial: Pressure Altitude and Density Altitude

This video presents an introduction to the concepts 'pressure altitude' and 'density altitude'. NOTE 1: There's a mistake of definition at 7m06s. "Universal gas constant" should be "Specific gas constant". NOTE 2: Comments are welcome but are censored to prevent viewer chats from spinning into arguments and name calling. If approved, your comments may take a day or two to show up. The video uses excerpts from Dr. Gudmundsson's textbook, "General Aviation Aircraft Design - Applied Methods and Procedures," published by Elsevier in 2013. The book is available from multiple outlets. Among those are: http://www.amazon.com/General-Aviatio... and http://store.elsevier.com/product.jsp...
