Here is a link to Nelsons book "Flight Stability and automatic Control". The second link is to Etkin's book, which I will refer to occasionally.

Course Grading:

Homework: 25%
Exam I  : 25%
Exam II : 25%
Exam III: 25%

NOTE: The above grading scheme is the 'worst case' method of computing your final grade.If you demonstrate 
        a significant increase in performance throughout the semester, your grade could well be higher.

HOMEWORK SOLUTION FORMAT ***IMPORTANT***

The homework will be posted at this website in the 'Homework' folder. The procedure for turning in homework is the following:
1. Download the Word document to your pc.
2. Modify the document to leave enough space DIRECTLY BENEATH EACH PART OF EACH PROBLEM to insert your solution,
3. Your solution can be typed, hand-written, or a mix of the two. If it is hand-written and the grader finds it to be illegible, 
   it will not be graded (i.e. that part will receive a grade of zero).
4. Homework will be collected during the class at which it is due (as stated at the top of the homework.
5. Pages should be stapled, and your name should be on every page.

NOTE: Homework turned in that does not adhere to the above procedure (esp. 2) will NOT be graded (i.e. given a grade of zero).

RATIONALE: The rationale for requiring that this procedure be strictly followed is twofold. First, it makes the grader's life 
MUCH easier. Second, it will be more amenable to review as preparation for an exam.

Course Outcomes:

At the completion of this course the average student should:

1. Have a firm understanding of the contribution of aircraft elements to overall static stability.

2. Have a firm grasp of linearized longitudinal and lateral state space differential equations that model aircraft dynamics.

3. Have a good practical understanding of dynamic paramters including time constants, natural frequencies, and damping ratios.

4. Have a firm understanding of how Laplace transforms can be used to analyze aircraft dynamics for both initial conditions and forcing inputs.

5. Have a firm understanding of frequency response functions.

6. Have an understanding of feedback control toips, including PID controllers, the Routh arra, and the root locus.

Accessibility Statement:

Iowa State University is committed to assuring that all educational activities are free from discrimination and harassment 
based on disability status.  Students requesting accommodations for a documented disability are required to work directly 
with staff in Student Accessibility Services (SAS) to establish eligibility and learn about related processes before 
accommodations will be identified.  After eligibility is established, SAS staff will create and issue a Notification Letter 
for each course listing approved reasonable accommodations.  This document will be made available to the student and instructor 
either electronically or in hard-copy every semester.  Students and instructors are encouraged to review contents of the 
Notification Letters as early in the semester as possible to identify a specific, timely plan to deliver/receive the indicated 
accommodations.  Reasonable accommodations are not retroactive in nature and are not intended to be an unfair advantage.  
Additional information or assistance is available online at www.sas.dso.iastate.edu, by contacting SAS staff by email at 
accessibility@iastate.edu, or by calling 515-294-7220. Student Accessibility Services is a unit in the Dean of Students Office 
located at 1076 Student Services Building.

COE PREREQUISITE POLICY:

It is the policy of the Department of Aerospace Engineering and the College of Engineering to require all students enrolled in this course 
to have satisfied all of the course’s prerequisite requirements. If it is discovered that a student has not met any applicable prerequisite 
requirements, he/she will be required to immediately drop the course. The failure to drop the course will result in a final course grade of  
‘F’, regardless of course performance. Students who discover they have improperly enrolled in a course without meeting the applicable 
prerequisite requirements are strongly encouraged to meet with advising staff to promptly drop the course and make alternative scheduling 
arrangements or discuss if an official waiver of the pre-requisite requirements may be applicable.
