This paper investigates wing aerodynamic characteristics used for bi-plane micro-air vehicles. Surface pressure distributions of two-dimensional biplane airfoils (4% cambered-plate airfoil) were measured at a chord Reynolds number of 6.4 × 104. Lift characteristics of three-dimensional biplane rectangular wings (aspect ratio of 3) were also measured at the same Reynolds number. It was indicated that the behaviors of laminar separation bubble formed both on the upper and lower airfoils/wings affects their lift characteristics. Bi-plane wings with positive stagger, i.e. protruded upper wing indicated higher maximum lift coefficient. This is caused by different behaviors of laminar separation bubble formed on the wing.

In the Reynolds number region lower than approximately 1.0 × 105, which corresponds to the Reynolds number region of a Micro Air Vehicle, thinner and sharper leading edge airfoil performs better than thicker and blunter one. This research focuses on the difference in flowfields which are clarified by means of streamline calculation and surface pressure distribution measurement. Numerical studies were performed to the blunt type NACA0012 airfoil and both numerical and experimental studies were performed to the thinner type 4% cambered-plate airfoil. The performance of the NACA0012 airfoil is deteriorated with decreasing Reynolds number, whereas that of the 4% circular arc cambered-plate airfoil is not affected. The deterioration of the NACA0012 airfoil performance is mainly due to the laminar boundary layer separation near the trailing edge; such phenomena are not essential to the performance in the cambered-plate airfoil results. This paper also demonstrates that the flow separation at the trailing edge can be estimated from the temporal amplification factor of the oscillatory mode which is calculated by the global linear stability analysis.

In the normal operation of the scheduled flights, airline pilots maintain the level of the flight safety, economic fuel saving expenditure, punctual flight operation and passenger comfort. In this paper, we use the term "Flight Management Skill" as an operation skill with considering the above-mentioned factors. For the research of the Flight Management Skill, the high experimental cost and the availability of the full-flight simulator are the difficulty of the research. For the purpose of performing the Flight Management Skill research easily, we have developed PC tool, which displays a simplified flight situation and records the operation history. The PC tool does not reproduce all the components of the actual flight; we have to extract the significant items which affect the decision-making process of the actual flight. In the previous report, we have conducted experiments under the condition of Haneda airport runway closure due to earthquake. In the questionnaire, we have found comments claiming that, for the information of Haneda airport being re-opened was not automatically reported, the examinee decided to divert to other Airport without knowing the information. In this research, the PC tool has been modified so that the re-opening information of the destination airport is automatically reported. The experimental results demonstrate essentially the same results as the full flight simulator in the viewpoint of the difference between inexperienced and experienced pilots.
