Parasite drag - skin friction (drag of all parts of the aeroplane that do not contribute to lift)
Induced Drag - caused by angle of attack
-increases as angle of attack increases and decreases as angle of attack decreases
-high aspect ratio and narrow chord has the least induced drag, small aspect ratio and wide chord has most induced drag
- Skin Friction - friction on the skin from the air
- Form Drag - resistance of body parts moving through the air
- Interference Drag - assembled aircraft creates more drag than the parts would if they were individuals
- Leakage Drag - air leaks out doors and windows
-Slow, clean and heavy is the condition with the most induced drag.
-Wingtip vortices's produce induced drag.
