When I go to these events, gates open normally at 8:00am and there will already be about a mile queue waiting for them to open, parking on the airfield and then going through security checking and being searched, and your camera equipment examined etc can also take up to an hour, through 4 separate gateways across the airfield, with up to around 5 queues at each security gate, can you gauge just how many people and cars turn up at these events. Then you have about 1 to 2 mile walking once past security to reach a decent spot on the crowd line for photography purposes.
Flying starts at 10:00am and even when arriving at the gates about 7:00am after a 2-hour drive, you can still be clearing the security checks at 9:30. So is a 5;00am an early enough start for you? I already am an early bird in order to catch that worm
Flying stops at about 5:30pm, and then you have to return to your car, and it can then take an hour or more to exit the airfield. So by the time you get on the road, rush hour traffic has gone, so you normally take the same 2-hour drive home. So I take a comfort break on the airfield and let the others fight their way out of the jams.
Now if they could somehow set up about a thousand destination chargers on the airfield, then EV's could be charging while the show is on. Trying to get onto a charger on the way home, from the event is going to be difficult within a large radius of the event as many others will desperate to also charge.
Until they can either greatly enhance the range from an EV, or the infrastructure is significantly expanded and enhanced, EVs will struggle.
To give you a flavour of the size of these events, RIAT attracts over 200,000 spectators and these are only the officially counted one who brought tickets. There are many locations dotted around the edge of these airfields that become temporary camping sites and loads of people camp there and view through the fence, or just rock up, park on these campsites and view the display without going onto the airfield, so there could be many more thousands trying to get home.
