Problem1. Air Mauritius Ltd publishes a weekly flight log report, which tracks each aircraft and the number of hours which were flown by an individual pilot in each aircraft. A separate report is prepared for each pilot and is employed to monitor flight proficiency for the two types of aircrafts (Fixed Wing and Rotary Wing) which a pilot might be qualified to fly. The following business rules apply to this report. Pilots may be assigned to fly different aircraft each day by the flight-scheduling manager. Each aircraft has a single crew chief permanently assigned to perform maintenance on the aircraft, although a crew chief might crew more than one aircraft. An aircraft number identifies each aircraft. There are several aircraft in fleet. An aircraft number is unique, independent of aircraft type. Pilots are identified by their flying-license-number and crew chief by employee-id.

Additional information:

All aircraft have seating-capacity data. Fixed wing aircraft have number-of-engine data and Rotary aircraft have speed-of-blade data.
