  • On Dec 7 and 8th, 30 of the 48 hours were filled with low flying arrivals over Milton (63% of the hours in these 2 days).
  • Of the 46 hours of arrivals to the 4’s, only 30 hours were at times when the winds were from the N, NE or E (65% of the 46 hours) when the 4’s need to be used for safety reasons.
  • The remaining 16 hours when the 4’s were used for arrivals (35% of the time the R4R/L were used), the winds were NW, W, SE or calm.
  • During these 8 days, Milton received planes for 16 hours when wind direction and speed would allow other arrival runway choices.  
  • Using the PRAS* goals, the FAA failed 5 times out of 8 to adhere to  the goal not to “dwell” over any community for more than 7 hours in a 24 hour period.
  • Using the PRAS* goals, the FAA failed 2 times out of 6 to adhere to the goal not to “persist” over any community  for more than 23 hours over a 3 day consecutive period.

*Preferential Runway Advisory System (PRAS). These goals were developed by a PRAS Advisory Committee in 1980-83. The goals were abandoned in 2012 partly because the FAA seldom adhered to them. However, they are currently our best gauge of whether or not there is a fair distribution of Logan airport burden.
