Domanda		Risposta
pull of gravity It is caused by the downward pull of gravity inizia ad imparare		siła grawitacji
propel Thrust is the forward force which propels the airplane through the air. inizia ad imparare		napędzać
retarding Opposing thrust is drag, which is a backward, or rerarding, force that limits the speed of the airplane inizia ad imparare		uwsteczniający

coefficient The coefficient of lift is a way to measure lift as it relates to angle of attack. inizia ad imparare		współczynnik
occur Every airplane has an angle of attack where maximum lift occurs. inizia ad imparare		występować
peak As angle of attack increases, CL also increases. This continues to a point where CL peaks. inizia ad imparare		osiagąć szczyt/maksimum
separation inizia ad imparare		oderwanie
disruption Increasing the angle of attack beyond CLmax causes progresive disruption of airflow from the upper surface of the wing. inizia ad imparare		zakłócenie
