"CASA this week published the deliberations of a Technical Working Group (TWG) that has recommended several changes to the Class 5 medical standard limitations, but will leave the 2000-kg restriction in place.
The TWG met in November last year under the supervision of Principal Medical Officer Kate Manderson, making several recommendations to CASA through the Aviation Safety Advisory Panel (ASAP), which, if accepted, could see modifications to most of the restrictions applied operations under the Class 5 self-declared medical.
Among the key recommendations are:
the 2000-kg MTOW limit remain in place
POB limit of two be increased to four
the 10,000-feet altitude limit remain in place, but be reviewed under the Class 4 framework
controlled airspace access remain in place
aerobatics be permitted provided the aircraft has no passengers and not be flown in competition or air shows
day VFR only be retained, but IFR be reviewed under the Class 4 framework
formation flying be permitted provided with one passenger only and not in air shows or flying displays
the requirement for a Class 5 candidate to never have been refused a CASA medical be removed
the ban on medical stimulants to treat ADHD be removed."
