NOTE-
*Configuration diversity and the fact that airworthiness certificates are issued to aircraft builders, vice manufacturers,
necessitates the assignment of generic aircraft type designators based on cruise performance, rather than specific
manufacturer and normal descriptive/performance information.
**All performance criteria has been estimated because configuration diversity precludes determining precise
aircraft-specific information.
