2.1 Overview: This dataset was provided to us by FAA (Federal Aviation Administration). We were given a couple of datasets out of which we considered one dataset as they all have same attributes with different dates as the flight data should be recorded at least once per second. This dataset is comprising of 1,58,445 rows and 108 columns with a total size of 125MB. The minimum set for RoAR is the parameters recorded conforming to the minimum requirements of AC 135-14B they are - Latitude, Longitude, Barometric Altitude and Date/Time. This specification applies to rotorcraft including scale and remote-control helicopters. This dataset consists of all the engineering units of the RoAR parameter fields for the individual flight messages. Figure 1: Dataset Overview The attributes in the Rotorcraft Analysis Recording (RoAR) Specification are primarily categorized into 2 sections: 1. Meta data section 2. Flight Message Section As there are several attributes, we further categorized them into different sections as in what field is the attribute is belonging to. The following are the below sections considered.

 Metadata: It includes different properties of the flight such as weather conditions, time, etc., which is used for the data management.  Flight State Altitudes: It is used to measure an aircraft's altitude at standard air pressure, expressed in hundreds of feet.  Position: It defines the point where the rotorcraft is heading too i.e., vertical angle or horizontal angle.  Airframe: An airframe is a basic structure of an airplane or spacecraft excluding its power plant and instrumentation  Acceleration: A pilot in a steep turn may experience forces of acceleration equivalent to many times the force of gravity. Acceleration is described in units of the force called - Gs.  Flight controls: Aircraft flight control systems consist of primary and secondary systems. The ailerons, elevator, and rudder constitute the primary control system and are required to control an aircraft safely during flight.  Engine: It has the power component of an aircraft propulsion system. Most aircraft engines are either piston engines or gas turbines  Rotors: Rotors is an array to support one or multiple rotors  Navigation: Includes Global Navigation Satellite System (GNSS).
