Determine the value of tail angle of attack if, elevator floats down b

1.	Determine the value of tail angle of attack if, elevator floats down by 1.8 degree. Consider CHδe as 0.003 and CHɑt as -0.006.(a) 0.9(b) 2.5(c) 3.4(d) 1.8The question was posed to me by my college professor while I was bunking the class.The question is from Stick-Free Stability in portion Stability, Control, and Handling Qualities of Aircraft Design
Answer» The correct CHOICE is (a) 0.9 To explain I would say: Given, ELEVATOR float E = 1.8°. CHδe = 0.003, CHɑt=-0.006. Now, TAIL angle of ATTACK = – e* CHδe / CHɑt = -1.8*0.003/-0.006 = 0.9°.
