découvriras également tes obligations en tant qu’exploitant drone (c’est le nom un peu barbare donné dans le milieu professionnel pour désigner ton entreprise déclarée à la dgac)
la deuxième journée de la formation pilote drone est consacrée à tout savoir sur les drones
la suite et fin de ce que tu dois connaître sur la réglementation drone (je t’avais dit c’est ultra complet(xe) 😅)
on aborde également la météo et l’aérologie (et oui ça peut avoir des incidences sur tes vols)
et tu test drone x wing
apprendras à lire une carte aéronautique pour mieux préparer ton plan de vol et surtout connaître les législations de l’espace. aérien, les lois à proximité d’un aéroport ou aérodrome
en parlant de préparation de vol, c’est d’ailleurs une grosse partie de la journée où lilian partage ses connaissances du terrain
lilian, co-fondateur de reflet du monde, était cadreur en drone sur la série baron noir de canal + notamment
et il t’expliquera parfaitement comment obtenir une autorisation préfectorale de survol en agglomération ou en zones ar drone 2.0
réglementées
son retour d’expérience est fantastique !
cette journée de formation pilote drone est uniquement consacrée à la partie technique du drone
c’est à dire que jim, un des formateurs, t’emmène avec lui dans son univers. pour te présenter et t’apprendre le fonctionnement d’un drone
tu passeras tout en revue,

monster or eagle cameras and the low light cameras such as the owl or night wolf
resolution and latency – i’ve grouped these two together as they go hand in hand, the higher resolution you run the more latency you are likely to see! analogue cameras are rated in tvl which is the number of horizontal lines across the screen
due to the added latency i would recommend sticking with a camera the same resolution as your goggles (typically 600tvl)
another consideration is weather you want 4:3 or 16:9 resolution with 4:3 being the most common
camera features – some cameras have special feature such as the ability to monitor your battery voltage and display it on screen
other options are low light cameras that can see in nearly total darkness
mini and even micro cameras are available that may be a better choice for smaller builds whilst some cameras offer a microphone for audio feeds
lens – different sized lenses give a different fields of view (fov) which allow the pilot to see more around them
the higher the field of view the more fisheye effect you will also have to deal with
8mm – the old standard, very narrow fov
2
5mm – a great all rounder lens, same view as the gopro!
2
1mm – a wide angle lens, this gives a great view for freestyle flying but may be                    too wide for racing
a comparison of lenses can be seen in this video
the video transmitter takes the signal from your camera and sends it out through your antenna
power output – different vtx’s pump out your video at different power levels
these often range from 25mw to 800mw with some offering a means of switching power output
channel options – most modern vtx’s can run the majority of channel bands including raceband
as long as the vtx channel list is compatible with your receiver you should be fine!
signal quality – this one really comes down to who you’ll be flying with, you’ll notice that some vtxs offer the same power and channel options yet cost up to four times as much! the reason for this is that the cheaper vtxs spit out noise over a much wider range than the selected channel which can lead to interference in other pilots video feeds
if you intend to fly on your own a cheap vtx will work great for you however if you intend to fly in larger groups or at race events you really need a clean transmitter like the tbs unify pro or the irc tramp
switching options – if you do intend to fly with other people or at race events then you’ll often have to change channel to ensure everyone can get clean video
traditionally vtxs have a small push button you can use to cycle through video channels, bands and power levels, the channel is then shown via a leds on the vtx itself
the more race friendly transmitters actually connect up to your flight controller and allow channel changing via an osd or a taranis transmitter
although it sounds like a little feature it makes a huge difference when flying in groups of over three pilots and is one i cannot go without anymore
be sure to check what is legal in your country! some vtx have limits of 25 or 200mw
the best way to improve your video range or clarity isn’t necessarily increasing the vtx output power but is actually getting a good pair of antennas
those black dipole antennas you get with cheap goggles or vtxs referred to as ‘rubber duckies’ really don’t perform well and are often binned and replaced with a high end antenna
an fpv setup requires two antennas, one to send out the video and another to receive it
things to consider​​​​​
antenna type – different antenna designs have different performance, without going into too much detail dipoles perform poorly where as circular polarized antennas perform well
more innovative recent antennas such as tbs triumph or pagoda push video range even further
a patch antenna can be used to increase range but only in one direction and should only be used as a receiving antenna
connector type – antennas come with two connector types sma and rp-sma both can talk to each other fine but you need to make sure they match your vtx or goggles connectors
failing that adaptors are available
polarization – the antenna itself can come in tow flavors rhcp and lhcp both work the same but they must match in order to get a signal
by having different polarizations it is possible to get more pilots in the air at once
robustness – obviously the antenna on the drone will be subject to a lot more abuse than the one on your goggles! for this reason i recommend using your best/most delicate antenna as a receiver and using a durable protected antenna on the drone
hopefully you’ve already chosen your drone size in inches so you know your prop size! my honest recommendation for a beginner is to get a big box of cheap props as you will break them incredibly quickly
props are often denoted as a axbxc where a is the size in inches, b is the pitch (angle of the prop) and c is the number of blades
a 5x4x3 for example is a 5″ prop with a 40 degree pitch and three blades (triblade) this may also be described as a 5040 triblade and is coincidently
