11. The reference for a wing would be the plane area rather than the frontal area . 12. Mirror neurons were discovered in the 1990s in frontal area F5 of the monkey cortex. 13. These included better air-brakes with an increased frontal area . 14. Carbon emissions are reduced as a function of low weight and a small frontal area . 15. The tandem seating allowed the body to be long and narrow, with a low frontal area . 16. Both effects together, velocity and frontal area , yield a thrust-to-drag ratio of 8 for the legs. 17. Modern fairings increase the frontal area at most by 5 % compared to a naked machine. 18. In most cases of sinus barotrauma, localized pain to the frontal area is the predominant symptom. 19. Originally the fairings were cowlings put around the front of the bike, increasing its frontal area . 20. This results in a more horizontal back and presents the minimum frontal area to reduce drag.
