Longitudinal Dynamic Modes — Quiz
Test your understanding of longitudinal dynamic modes with 5 practice questions.
Practice Questions
Question 1
Which longitudinal dynamic mode is the rapid oscillatory motion mainly involving angle of attack and pitch rate?
Question 2
Which longitudinal dynamic mode is characterized by a slow exchange between kinetic energy and potential energy, with speed and altitude changing noticeably?
Question 3
In the phugoid mode, which aircraft variable typically changes very little compared with speed and altitude?
Question 4
Which longitudinal dynamic mode is usually more strongly damped and therefore dies out faster?
Question 5
A brief elevator disturbance that mainly changes pitch attitude and angle of attack first excites which longitudinal mode?
