This seems to be going around the houses a bit and comparing a VGS operation and requirements with a BGA one is like comparing apples and oranges.
Lets not focus on Blue only as the OP seems to have become obesessed with and if counting launches lets stop conveniently ignoring all the other flights that happen for GS, AGT, PAX sometime and staff training and currency to be able to bash the VGS’s
I am not saying the VGS system is without fault but there does need to be a level of fairness thats seems to be being overlooked.
As someone who wanted to be an instructor on a VGS but can’t (medical) let me try and add some value with comparison between my experience and going through the BGA route I am now on.
VGS - new Blue group every week requiring H&S and site brief for 10+ (kids and accompanying staff
BGA - visitor will be given a basic brief on where the toilets are and what to expect.
VGS - parachute and egress training for 10 kids plus accompanying staff in case pax flight an option
BGA - breifed on how to put parachute on next to the aircraft before flight.
VGS - Parachutes checked and documention completed they have been checked and supervised
BGA - Member checks when parachute was last packed, last 12 months, and pins look good and takes to aircraft
VGS - either have to do all the ground handling or teach each new group of cadets
BGA - generally only have to deal with small number of new members at any one time and not normally as frequently as twice a week.
VGS - DI aircraft and chack and complete all the paperwork for the aircraft.
BGA - DI aircraft and single date and signature required.
VGS - monthly, quartlerly, annual checks on pilots, staff needing DBS, 1st Aid, climatic injuries, fire training, human factors…
BGA - annual check flight with CFI required
VGS - Medical annually with MO at parent station med centre to standard set by RAF (AP1269) and need to meet PULHEEMS from JSP’s
BGA - Self certify and doctors form that they meet DVLA Class 2 driver medical
Both will do their best to get a 10 minute flight but in most instances it will be two 6 or 7 mins for VGS in the majority of instances
My halcyon days of VGS as a cadet they had about 10 aircraft, still only about 10-12 kids for experience flights in addition to the staff and GS cadets and flew until sunset. There were just a lot more of them then . One of my favourite flights I watched the sunset twice, first from the cockpit sat on the ground and then again from about 1400ft after leaving home around 7am and getting to the VGS around 0830 a summer day that ended around 2030 and I got home around 2200, now theres duty hours limits for VGS and those include travel to and from the VGS. The BGA clubs can carry on until last landing 30 mins after sunset or everyone has had enough if earlier.
Edited to add if looking at BGA clubs not all are junior frindly either which is something else I have seen regualarly overlooked to support the argument of how much more accessible they are.
