ASE 167M Lab #1: Orientation Flight Drew Rosecrans March 3, 2010 Abstract An experiment was done to familiarize ourselves with the simulator. The main objectives of this lab were to become more familiar with the flight simulator by using the instruments to control the flaps, yoke, etc. In order to become familiar with the instruments, a flight was flown that involved the manifold pressure, flaps, and rate of climb. The maximum rate of climb can be determined by both theory and graphical interpretation, as was the maximum flight path angle. The maximum rate of climb from graphical interpretation was 1250 ft/min, while the theoretical value was 1259 ft/min. In addition, the maximum theoretical flight path angle was 11:46_, while the graphical interpretation provided 11:15_. Furthermore, the maximum rate of descent from graphical interpretation was 250 ft/min, which closely matched the theoretical value of 214 ft/min. Likewise, the theoretical minimum glide angle was 0:99_ that closely matched the graphical interpretation value of 1:16_. The simulation allowed the lab group to become more familiar with both the cockpit and how the simulation works without the aid of the instructor. 1 Objectives 1. Operate the flaps, throttle, propeller RPM control, control yoke, rudder pedals, and various switches without instructor aid. Prior to this flight the student should be able to explain verbally the purpose and operation of all of the various switches gauges and controls in the simulator. 2. Explain qualitatively the relationships between pitch, flight path angle, power, flaps, airspeed, and trim. 2 Discussion The flaps are hinged surfaces along the trailing edge of the wing. They are an important part of the aircraft that are used during landing and takeoff mainly. The amount of lift generated by an aircraft depends on the airspeed, the shape of the airfoil, and the area of the wing. When the flaps are down they increase the area and the camber of the airfoil to produce the extra lift needed for takeoff. The flaps add extra lift by adjusting the shape of the airfoil, but they also increase the drag of the airplane. This decreases the airspeed. This is very useful when landing. The flaps allow the pilot to descend at a slower airspeed for landing, by increasing the drag and increasing the lift. The rate of climb (R/C) in ft/min of the aircraft is the rate of change of the altitude. In addition, the theoretical rate of climb may be calculated from a quadratic fit to data from the following equation: (1)
