With advanced sensor fusion, including millimeter-wave radar and binocular visual obstacle avoidance system, the JOUAV's CW-15 makes flights by this flying device fully autonomous and safe even in low-light conditions.

However, when flying, especially at night, it will be challenging to make a proper estimation of the time remaining for the flight as the visibility is not that good. Pay attention to the battery during your flight.

This can be facilitated by adding lights to the drone facing downwards which would illuminate the space directly beneath the drone, thereby making it easier for pilots to make quicker and more precise positional judgments. Indeed, added visibility may be especially useful in situations involving emergencies or searches where rapid responses may be extremely critical.

As always speed is vital when responding to chemical injuries - reducing contact time will help to limit penetration. With HF contact at low concentrations, pain may not be felt immediately so it is important to react quickly to any suspected contamination. The use of appropriate PPE is vital and particular attention should be paid to the selection of the correct material for gloves and for them to be replaced regularly.

To keep a line of sight with the drone, make use of the feature in the app that allows setting a maximum flying distance.

The FAA has some very specific rules about when night begins and when it ends, and it has absolutely nothing to do with the sunset. According to the FAA, "night" is defined as:

Otherwise, any pilot planning to wear night-vision goggles must have some backup plan to remain visible, or the goggles must be capable of detecting all light within the visual spectrum. That becomes crucial to guaranteeing secure operation in the dimly lit environment.

Set the RTH altitude high enough to avoid obstacles. This should be tested manually, as you will want to make certain it will work in case you want it to do so.

First, go to manual mode; maybe auto mode won't handle the low light conditions any better. Then, open up the aperture between f/2.8 and f/4.0, enabling more light in, thus improving your exposure.

If conditions appear not safe, then you will want to delay flying. Always make sure your drone's lights are functioning properly so that you can see the drone and control it throughout the flight operation.

It takes your eyes some time to become accustomed to darkness, and this can be as long as 30 minutes. Preadapt your eyes in the darkness outside the cockpit or cover them to avoid bright lights that would disturb your adaptation on any flight. A number of pilots have found that wearing red-tinted glasses for a short time will help preserve their night vision.

The advantages of these extra lights go beyond safety alone. They can provide special effects to your photos and videos that you will be taking at night.

While difficult to notice, there were numerous successful techniques one could apply in order to spot a police drone at night. Here is what you need to know in order to find a police drone in the dark:

So, good light is essential. In low light, your camera sensor has to work much harder, often having to use high ISO settings, such as 1600-6400, or very slow shutter speeds. This can make photos appear grainy or blurry.

In 2021, the Federal Aviation Administration made its latest and greatest rules, affecting nighttime flights of drones to make sure that both commercial and recreational pilots are operating within the bounds of the law. Here's what you need to know to stay safe and compliant with these new requirements.

The maximum altitude for flying a drone at night is generally the same as what the FAA permits for flying during the daytime, thus usually 400 feet above ground level in uncontrolled airspace. However, operators should take note that local regulations might further restrict flying conditions. It is important to maintain a safe distance from obstacles like buildings and trees.

That's because it used to require a special waiver to fly at night. However, with years of safe flying records coming in from the drone community, the FAA has dropped the waiver requirement. Today, you need only additional training for night-flight if you're already certified.

The mechanical washing of water will remove chemical from the surface of the skin or eyes. It will also dilute the chemical. This is all in an effort to limit penetration. Calcium Gluconate gel is then applied to the skin to provide a calcium source for the fluoride ions to chelate rather than the calcium within the body cells. In hospital, Calcium Gluconate may be applied by subcutaneous injection, intravenously or by intra-arterial injection for the fingers and hands.

Cold weather tends to slow down battery performance. It is crucial then that the batteries are fully charged, and extra ones can be packed when needed.

Yes, recreational drone pilots can fly at night but with some particular regulations. In the U.S., all drones flown at night should be equipped with anti-collision lights visible from at least three statute miles, according to the FAA.

In addition to being corrosive, HF is also toxic. As with all acids, the H+ ion causes the chemical lesions due to reactions with tissue proteins. With higher concentrations of HF these lesions are more marked. The toxicity of the HF derives from the Fluoride ions (F-). HF also has the ability to penetrate tissue in an undissociated form with the toxic fluoride ions being released later. Fluoride ions have an affinity for Calcium and Magnesium in our body cells and will readily chelate these ions causing a painful local imbalance. The chelated Ca2+ and Mg2+ then have no action in the usual body equilibrium. Chelation of calcium can result in hypocalcaemia which can lead to cardiac arrhythmias and cardiac arrest. The degree of systemic harm is increased by the concentration of HF - the consequences are more severe at higher concentrations - and the contact time of the chemical with the tissues. Anhydrous Hydrofluoric Acid can have fatal effects when in contact with only 1% of body area, concentrations of less than 20% HF can be lethal when affecting 20% TBSA. Low concentrations of HF (5%) can be lethal in ingestion and inhalation injuries.

I would like to know the date and time that the CAD message was created as well as the reason for its creation (was it a 999 call? etc).

It takes your eyes roughly 30 minutes to fully dark adapt, and even brief contact with white light breaks that dark adaptation-a process called "photo bleaching.".

Avoid bright lights, either in the form of illuminated launch areas or control screens on your drone. Such things will only distract you and reduce your effectiveness at tracking your drone in the night sky. Minimize screen time to preserve your situational awareness, enabling your eyes to adapt to low-light conditions.

These laws may sound strict, but they are there to protect the safety and legality of drone activities. This is how pilots can act responsibly and safely during night flying by following the standards set by CASA.

If you have plenty of light, then the ISO setting can be much lower, around 100-400, and shutter speeds much quicker. The result will be a sharper image with less noise.

Commercial operators will also have to provide for pilot training and testing, maintain full training records, conduct JSA and risk assessment for each flight, and document all processes.

Working with a visual observer in nighttime flight could multiply the benefits in overall safety and operational efficiency.

Be on the lookout for optical illusions. Slender, dark objects seen against a background of bright sky or water may appear stumpy. Conversely, huge, pale portions of clouds against a darker sky background often seem tiny.

Flying a drone at night does come with different challenges, which need very careful planning and alterations to make the flight safe and successful. Here are some key technical considerations.

This will imply that you must be in a position to view and observe your drone and also the environment where it has been flying at all times.

Probably the easiest way to spot a police drone at night is by observing the different colored lights it emits. Most police drones have light features that come in distinguishing red and green. You can spot them from a distance. Be wary of colored lights hovering in the sky. If you can spot one far away, binoculars or even a telescope can provide a closer view to confirm if it's truly a drone.

This should be easily observable from a reasonable distance away to help prevent potential collisions with other users of the airspace.

In nighttime flying, depth perception is usually a problem. Many a time, one may have difficulty in distance estimation. To limit this problem, it may be useful to set a geofence, which confines the operational distance of the drone within, say, 200 meters.

Flying in the night reduces your ability to see obstacles clearly. Your drone should be equipped with obstacle avoidance sensors, which become very important in carrying out safe operations in the dark.

Limitations of this method include the risk of hypothermia due to the volumes of water and washing times required (15 minutes/60l per minute flow rate). The wash-in effect (due to osmotic flow into the skin or eyes) when washing with water can cause further penetration of the chemical. In addition, Calcium Gluconate gel has little effect on the H+ions, it requires multiple applications which may cause additional pain on open wounds and there is also the possibility of reversibility of chelation between the calcium provided by the gel and cellular calcium. Calcium Gluconate gel must not be used in the eyes as this can result in corneal calcification.

Commercial operators can fly at night but are pretty strictly regulated. To fly at night requires a Remote Operator Certificate. It is not sufficient to have a Remote Pilot Licence (RePL or REPL); any night flying must be conducted under the auspices of a ReOC holder.

These factors depend on the size of your drone, its effective lighting conditions, and weather, and may also include your eyesight, which determines the maximum VLOS distance.

Get used to how these sensors work in daylight, and fly more slowly to give yourself more time to react to unexpected obstacles.

If you experience optical illusions while flying, follow your instruments and rely on your training. Using experience will go a long way toward ensuring that you and the drone are kept out of harm's way.

The visual observer should make systematic scans of the environment. Position the drone at the 12 o'clock position and make broad horizontal scans to the left-that is, 9 o'clock-and right, that is, 3 o'clock. Extend the scan vertically to ensure comprehensive situational awareness.

Fly shorter distances since this will be a precautionary measure to ensure you will have sufficient power to return home safely.

Choose very well an acquaintance with drone operations and one who understands the particular risks associated with night flying. An observer plays a vital part in maintaining the visual line of sight and also detecting obstacles.

All of these can be done at night by hobbyists, provided they follow the same FAA regulations as other recreational pilots, having the proper lighting for visibility and not violating any local ordinances. A hobbyist also needs to be aware of the capabilities of their drone and practice in well-lit conditions before flying in the dark.

Yes, in the United States, both Part 107-licensed and recreational drone operators can fly at night without a waiver by equipping their drones with anti-collision lights visible from up to three statute miles away. This rule, enacted in mid-2021, empowers drone operators further while making life easy on the FAA.

Hexafluorine® is a washing solution for the skin and the eyes. Its mechanical washing ability is at least as effective as water but has the added benefit of physically acting on both the H+ and F- ions by attracting, binding and rendering them harmless. This active washing ability results in a quicker return to safe physiological tissue pH with less washing solution, reduction in pain due to the chelation of the chemical aggressor and a non-corrosive run off making the first aid safer for casualty and responder.

If used within the first minute Hexafluorine® is able to eradicate the chemical before lesions develop. As a delayed wash - used after the first minute following a splash - Hexafluorine® will limit the progression of the lesion and facilitate the provision of secondary care. Hexafluorine® has an ability to chelate fluoride ions that is 100 times as effective as 2.5% Calcium Gluconate solution injected locally.

For night flights in the UK, the Civil Aviation Authority requires that your drone is equipped with at least one flashing green light.

Also, all the standard rules of operating a drone when flying at night remain the same. Maintaining line-of-sight with the drone and keeping flight altitudes below 122 meters-400 feet are examples.

Besides that, all other standard regulations concerning operation are in force for night flights: maintaining a visual line of sight with the drone and flight altitudes not higher than 122 meters (400 feet).

Stun baton flashlights typically have detachable parts, which can cause damage or lead to a broken weapon. Avoid those with flimsy bodies.

If surveillance concerns you, consider using technology that finds the drones for you. There are several apps for smartphones that use radio and Wi-Fi signals to locate drones and other devices dedicated to that purpose. Such devices will give you an idea of whether there is indeed a drone operating around you or otherwise, boosting your awareness regarding personal space.

Before each flight, make sure your lights are on and will last throughout your flight. This visibility requirement is a huge part of staying safe and compliant.

For instance, smaller drones would be more camouflaged against the night sky, and bad weather could make viewing much more difficult.

Also, keep in mind wind and/or weather conditions that have deteriorated by late afternoon or early evening. Take note of any light sources in the vicinity that may cause glare or disorientation during your flight.

Practical preparations and procedures will ensure a successful night flight. The section will help provide actionable tips for operators:

To prevent this from happening, use colored-lens flashlights to study before night flights. Colored lenses will help preserve your night vision so you can better view important details without having to reset your eyes' sensitivity.

Hydrofluoric Acid is a weak acid. This term should not be confused with the terms dilute and concentrated but it relates to how readily the H-F bond dissociates. It is perfectly possible to have a concentrated solution of a weak acid.

Hydrofluoric Acid is used to make most fluorine containing materials including Teflon and PTFE as well as refrigerants and pharmaceutical products. Its reactivity makes it ideal to etch or chemically mill metals and it is also widely used in the oil refining industry. The risk of HF exposure must also be considered in any situations where Lithium-Ion batteries are present due to Lithium Hexafluorophosphate electrolytes used.

Leveraging on technology for a better world. JOUAV has always been committed to using cutting-edge technology to benefit the society, making high-risk tasks safer and improving scientific research efficiently.

With the chemical formula HF, Hydrofluoric Acid is Hydrogen Fluoride dissolved in water. It is commercially produced from Calcium Fluoride (CaF2) and Sulphuric Acid (H2SO4). Hydrofluoric Acid is a highly corrosive and colourless acidic solution that should be stored in containers made from polyethylene or fluorocarbon plastic, lead or platinum due to its reactivity with many materials including glass.

What matters when flying your drone in the night is adjusting your camera settings to try getting as good footage as possible.

All night-flying drones require anti-collision lights. These are not normal, everyday lights; they need to be visible from three miles away and flash at a tempo that reduces the risk of collision.

Listening carefully is another useful device in trying to locate a police drone. Most drones, with whatever technology applied to them, really produce that buzzing or humming sound. That noise can be very much more perceivable when night falls and the general buzz of the day is greatly reduced. Keeping quiet and alert will heighten your chances of hearing an upcoming drone so you can precisely pinpoint where it is.

Sound is slightly different at night, and your drone will also be much noisier. Consider flying a model that works for more quieter flight.

To fly safely at night, it is crucial to keep oneself updated about the weather. Get current information through reliable sources of government meteorological agencies or weather services specializing in aviation regarding:

Featureless terrain, such as clouds, water, or snow, may cause ground lights to appear star-like. Counteract this effect by continuously scanning rather than concentrating on a single object; it will help maintain correct spatial orientation and will assist in avoiding judgment errors.

You can fly your drone at night in Canada. However, you have to follow the rules that have been laid down by Transport Canada. First of all, your drone shall be fitted with lights so you, as the pilot, and every other person on the ground can comfortably see it. These shall remain on during the flight.

Recreational users in Australia are not allowed to fly drones at night except in emergent situations. The usual flights are between the "Beginning of Day" and "End of Day," which corresponds to civil twilight hours. This normally gives about 20 minutes before sunrise and after sunset, depending on the region of operation.

However, laws can differ greatly over different international borders. For example, Canadian pilots must undergo special licensing to fly at night, while the UK and Australia have different regulations for flying at night.

The use of a system of communication with your observer: for example, terms to use and their corresponding hand signals. This will ensure smooth coordination and prompt responses during flights.

Once this limit is reached, it automatically stops and hovers for visibility, especially in dark environments or unfamiliar open areas.

Keep scanning your surroundings for any type of hazards, such as trees or electricity lines, especially if you are flying in a new area.

Nighttime flying can cause spatial disorientation because of bright lights and the absence of any visual reference. High-Intensity Runway Lights help locate a runway, but once you have identified your landing area, it is necessary to dim the lights to avoid any kind of depth perception illusion.

This time frame is referred to as "civil twilight." You might still have enough natural light in which to work, but beyond that, if you're still flying, first ensure you have night training and equipment.

Pay extra attention to the setup of the lighting; it should not produce any shadows or glare that could block your view. You must have a clear line-of-sight to support effective control and any possible emergency response.

The shutter speed should be between 1 and 4 seconds to avoid blurry shots with the movements of the drone. Besides this, set a manual focus to infinity. Autofocus may struggle in the dark.

It would be practical if you had at least one green flashing light on your drone that could be seen from a distance to enable this.

Of course, it is always much more visible if extra lights are added to the bike, like spotlights or additional strobes, even if the green flashing light is good enough to meet the standards.

Start by looking out for trees, buildings, power lines, or uneven terrain. Note these down with your geospatial data to help you plan a feasible flight path.

First and foremost, a daytime reconnaissance of the place you are going to fly is very much in order. This is the most logical step toward pinpointing possible hazards that could impede your drone's operation.

Now head to the safety settings and set the 'Max Distance' slider to a value with which you feel comfortable. The usual value ranges between 15-500 meters. This sets a Geo Fence around your take-off point, preventing the drone from going too far away from your line of sight.

Improve visibility at takeoff and landing zones with intense LED lights to simulate daylight conditions for enhanced line-of-sight and object avoidance capabilities.

This article looks into some of the legal considerations involved in flying at night, necessary equipment, and safety and regulations in your locality.

In addition, the pilot must be in a good position regarding the environment and aware of all the local laws that prohibit flying at night. It's also essential to maintain a visual line of sight with the drone at all times.
