What schools need for Digital Competence.

Size matters.
Several of us have completed our Operations manuals and attended the practical assessment. To our relief for the purpose of the assessment, we're allowed to use the advanced features our aircrafts have. After all, our Operations manuals specify the aircraft we fly, so it stands to reason the practical assessment is based on the operations manual, and indeed the limitations.However, one of the guidelines in CAP722 on Page 35 point 3.11 states
Operating within Visual Line of Sight means that the Remote Pilot is able to maintain direct, unaided (other than corrective lenses) visual contact with the UA which is sufficient to monitor its flight path in relation to other aircraft, persons, vessels, vehicles and structures for the purpose of avoiding collisions. Within the UK, VLOS operations are normally accepted out to a maximum distance of 500 m horizontally and 400 ft vertically from the Remote Pilot. Operations at a greater distance from the Remote Pilot may be permitted if an acceptable safety case is submitted. For example, if the aircraft is large it may be justifiable that its flight path can be monitored visually at a greater distance than 500 m. Conversely, for some small aircraft, operations out to a distance of 500m may mean it is not possible to assure or maintain adequate visual contact.
Indeed VLOS (Visual line of sight) is referred to time and time again for safe drone operation, but you see the thing is, 500m is pretty generous, incredibly generous to be honest. At night (which is prohibited without special permission granted) with the LED's lit up bright, 500m is just about workable, in the day, glance down at your controller, and you'd be forgiven for having a mild panic about where your aircraft is in the sky when you look up, and bear in mind, I'm talking here about a phantom. Bring in the much smaller Mavic and sure enough, theres a new problem we've got. From his estimation he shared with us earlier today, 270m is pretty much where VLOS ends. This is ok for most jobs (it's still a 1/2 km range from take off point East to West, or North to South) but it's enough to have him consider re-writing his ops manual to ensure that the flight test he has doesn't put him to a disadvantage.
This is something I hadn't considered as an issue until today, although I am sure most pilots who fly by fps only wouldn't even care, but should one go astray and become involved in an incident, I am certain this would become something prosecutors would consider in evidence against the Pilot.
Small drone.... harder to see in the distance, not all good things come in small packages.
Reminded me of the video above.

My first drone
Start cheap..... or really expensive.
Everything is hard until it becomes easy. I can still remember the first time I picked up a drone controller, the first time I took off, which coincidentally was the first time I smashed it into the ceiling. Shortly after I hit a wall, then the window, then I decided to take it outside and I remember fondly the walk around the field behind our estate looking for it. I was lucky, I found it, and thats when I really started learning how to control it.The machine was the Hubsan H107c, my second Hubsan H107 is still going strong, the first one landed in a small tub of water and the motor stopped working shorty after that. They say any landing is a good landing, but that one wasn't.
I've never really paid it much notice, but there are a multitude of RTF (ready to fly) drones on the market priced between £50-£300 pounds
. Most lack GPS and Gimballs so are poor for both control (for a beginner) and camera quality (some however do boast RTH [Return to Home] so if this is your budget make sure you get one with it). I'm sure the price of this technology will decrease as there's obviously a market for it, and many years ago, Gimballs and GPS was exclusive for machinery costing 10 times what it does now. But for the time being, starter drones should be considered just that. Practice machines, that
1) Won't cause too much damage when they hit the ground.
2) Won't break the bank if they do end up in a bad situation.
There's a lot of fun to be had with entry level drones, but don't build your hopes up. It's a steep learning curve and camera quality is going to be amateur at best.
On the other hand, if you're feeling more frugal, the Phantom 3 standard is now available for the incredible price of £400. For anyone with a couple of hours experience, or the ability to keep a quad in the air and away from walls for more than a few minutes, you'd find this machine a doddle to fly. With in built GPS this beauty will keep it's position in the sky without you touching the controller. It will make you feel like twice the pilot you are though, so crashing is still a high probability when you start taking risks. It also has a gimbal that on it's own is the best part of £250, this will make footage you capture look smooth and professional. On a quad of this price, this is exceptional.My advice, start with a pocket toy for indoor use. Get used to the controls then check the bank balance for a serious piece of kit that you can be confident you can control.

CAP 722, CAP 393 and CAA guidelines on safe drone use.
Drones are dangerous and some people are using them in wholly inappropriate ways (see previous story on the drone caught at 3,900 feet over London). There's a distinct difference between someone who wants to use their drone for commercial purposes and someone who wants to kill some time and have some fun, recklessly. Therefore I think the regulation needs to change to reflect that.
Not only should there be a distinct differentiation between individuals who fly these machines, but there should be a clearly defined difference between a toy, and a multi rotor aircraft. It's just wrong that a palm sized Hubsan H107 should be classified the same (below 7kg) as a DJI Phantom. Indoors, the toys are safe, outside, they should have a much lower ceiling of operation. To take a palm sized quad up to 400ft would just be ludicrous. Hilarious, but ludicrous. Nevertheless, the same wealthy 'pilots' that take the toys outside for a laugh, can also fly the much larger, and much more dangerous drones, in the same manner. Should they so please.
This reckless behaviour will ultimately lead to a minor, or major incident which will make it newsworthy and turn the already semi hostile onlookers into vehement objectors. So lets change the regulations now before we're forced to.
- All larger drones, ~ Dji Phantom sized and larger, should be registered like in the U.S. and clearly marked with a unique registration number. Owners, like car owners should be easily traceable. Regardless of whether they want to fly for leisure or profit.
- All qualified Drone pilots should be issued with pilots licences.
- Qualified Drone operators with PFCO should be given full freedom to fly safe. IE, 400 ft ceiling and 500m range.
- Unlicensed Drone operators (hobbyists) should be limited to lower altitudes 200ft altitude and 200m distance for example.
- The freedom to fly from a reasonable take off point should be encouraged and better defined as it causes no damage and harms no one. Similar to the 'right to roam' privileges. However if a land owner objects then the drone operator should move along.
- Police should be well briefed on the regulations and given the right to view a pilots licence and freedom and knowledge to interrogate a pilots flight log for the flight they've just conducted to ensure it's within safety guidelines. (after they've landed).

RUSTA - safety and danger.
Obviously the need for aerial imaging in London is crucial, only this week, on the apprentice we've seen beautiful shots of the Shard.
The reports state, however, that the aircraft was flying at around 4,900 feet, which is where the story gets interesting. There is no way that this was a legal or commercial operation. This was a hobbyist, or an idiot as some people call them. Flying above the 400 ft limit is illegal in the middle of nowhere without a specific safety case approval from the CAA, and only in controlled airspace as specified. If the local ATC didn't know about this, then they can't warn the pilots, and if they can't warn the pilots, what do you know, things like this happen, or worse.
I have over 120 flights under my belt, over 12 hours flying, and today was put under intense scrutiny in the safety of an open field, and let me be totally honest, when the crunch came, (an emergency drill, within Visual Line of Sight (VLOS) I almost lost it. Only by staying calm and regaining my composure did I avoid a collision. Drone's aren't easy things to fly. Just look on youtube for drone fails for hours of entertaining video of the drone population decreasing. Beyond visual line of sight (BVLOS) is a whole new ball game at 4900 feet, the drone is going to take a long time to descend, Vortex ring state may become an issue if descending vertically, and quickly. This is just mindless behaviour and the penalties ought to be severe. I'm in favour of a national database of Drones, a zero tolerance and effective method of grounding Quadcopters being flown recklessly and hefty prison sentences for clear breaches of CAA guidelines. Before it's too late.

Chromebooks
Here I am, blogging, (a Google service) on an Android (Google) device. It's fair to say, Google pretty much own the internet. Their services are usually well thought out, easy to use, functional and well integrated with both software and hardware.
My speciality is video. What's the first thing you think of when you think of video? YouTube, of course, a Google operated channel. So what's the best machine for creating YouTube content? Surely a Google machine? A Chromebook or Chromebox, no?
No. Absolutely not.
You see the weird thing is, although the Chromebooks are great machines, for organising files, great for synchronising your calendars with your android devices, great for managing your photo collections via Google photos, great for listening to music stored in your Google play account, great for spreadsheets and presentations using sheets or slides, and managing all of those things via cloud storage in your Google drive, they are without a doubt the worse choice for creating digital video content. Out of the box they simply will not do it.
It's bewildering when you think about it. A Mac comes with imovie.
Which means trawling through the marketplace for options. The best option having tried many, seems to be WeVideo, which is surprisingly capable for a server side option.
All of your video clips are uploaded from your SD card, via your Chromebook to WeVideo, you edit the video through an imovie-like interface (in chrome) but all the heavy rendering work is done back end, not on your local machine. So it works quite effectively. Even if uploading your raw video files can be very time consuming.
But here's the catch. It ain't free. It's not software provided by Google, and hence you either end up with a stonking great big watermark over your videos, or you bite the bullet and pay an annual subscription. No disrespect to the developers, they've got to make a living.
It just strikes me as odd. That the company behind the biggest video website in the world can be behind the only computer on the market that doesn't allow it's users to create digital video content. Not only easily, but pretty much at all.
If you're in the market for a new computer, bear in mind this one monumental drawback. Although YouTube does allow simple edits (once a file is uploaded, it's clunky and extremely limited) it's way of anything useable for even the most lightweight vlogger (video blogger for those of you unfamiliar with the term).
It's also impossible for schools to use to teach their pupils. Why? Because YouTube is blocked by most local education authorities.
If you're in the market for a lightweight, totally competent very, very easy to use machine, then knock yourself out. Chromebooks are great value for money. Just not if you're ever likely to need it to edit video.
Perhaps Google will buy WeVideo, perhaps they'll brand it Google, make it smarter and remove the watermark. But even if they did, it still wouldn't be the best machine for video editing, no serious (or even casual) YouTube content creator would consider a Google machine and that just seems ridiculous.
Come on Google, show us your A game.

Photographing fireworks.
Start with
ISO 200
f stop 8
Shutter 2"
Try handheld you may get some wobble, depending on your ability to hold a camera still, but the effects work as often as they fail. Tripod use is limited unless you're including the foreground on a wide shot, as firework tend to fill different parts of the sky, and zooming with a good optical telephoto is generally the way you'll want to capture an explosion.
