During the last several years, the FAA has been working toward the revision of both the Heliport Design advisory circular, AC150/5390-2B, and the Vertiport Design AC, AC150/5390-3. This work has been done in cooperation with Industry via meetings, discussions, and working papers. This report documents some of the some of the more significant issues that have been discussed during the 1997 to 2000 time period. While heliports and vertiports are different, many of the design issues are similar. Indeed, the FAA has previously announced its intentions to combine the two advisory circulars (AC) into one AC. This is why both subjects are addressed in the same report. |
