Q3: What is the impact of various sources on UFP levels?

Flight Activity:  DH8D is top contributor to UFP

  • DH8D contributes 57% to total aircraft UFPs
  • It makes up 66% of total aircraft fleet activities
    -Fight activities at ~70-80% of pre-lockdown operation
    -During aircraft takeoff/landing
    -Under southerly wind direction
    -Location: Ferry Terminal
    -Contribution of aircraft types to the overall UFP
(See figure in section below)

Flight Activity:  Other Aircraft Contribute Disproportionately 

  • C172, commonly used as a training aircraft in flight schools, making up 6.0% while contributing 8.2% of UFP
  • BE10, commonly used for corporate travel, making up 2.1%, while contributing 4.4%.
