Laser pointers aimed at aircraft: why it is a crime and what you face

A green dot in the sky, a quick sweep, a “just kidding” – that is how many cases begin that later end up with the public prosecutor. Anyone who points a laser pointer at an aircraft blinds an entire cockpit crew at the worst possible moment. German criminal law therefore treats it not as mischief but as a possible dangerous interference with air traffic under Section 315 StGB. This article explains what a laser beam physically does in the cockpit, what penalties you face and why plane spotters in particular, who stand under the approach path in the evening, should know about the topic.

Laser pointers at aircraft: the short answer

Yes, it is a crime. Anyone who shines a laser at an aircraft and thereby endangers people on board or on the ground can meet the elements of Section 315 StGB in Germany. The penalty range is six months to ten years in prison. For the basic intentional offense, the law provides only imprisonment; whether it is suspended on probation or mitigated in less serious cases is for the court to decide.

Two points make the provision especially sharp: even the attempt is punishable, so no aircraft actually has to have gotten into trouble. And anyone who acts negligently, for example someone who “just wanted to see how far the beam reaches,” can be punished. Depending on the case, further offenses and civil claims are added.

What Section 315 StGB actually regulates

The provision is titled “Dangerous interference with rail, ship and air traffic.” It lists several acts – damaging installations or vehicles, creating obstacles, giving false signs or signals – and ends with a catch-all clause for “a similar, equally dangerous interference.” According to the prevailing view, deliberately blinding an aircraft crew falls under this catch-all clause.

The second part of the offense is decisive: the interference must create a concrete danger to the life or limb of another person or to another’s property of significant value. With a fully loaded airliner on final approach, this threshold is not especially high. Whether it is met in an individual case is decided by investigators and courts based on the circumstances – phase of flight, duration, strength of the laser, the crew’s reaction.

The section is built in tiers:

Paragraph	Content	Penalty range
Para. 1	intentional interference with concrete danger	6 months to 10 years
Para. 2	attempt	punishable
Para. 3	intent to cause an accident or to enable or conceal another crime; serious damage to a person’s health or damage to the health of many people	not less than 1 year
Para. 4	less serious cases	3 months to 5 years (or 6 months to 5 years in cases under para. 3)
Para. 5	intentional interference, danger caused negligently	up to 5 years or a fine
Para. 6	interference and danger both negligent	up to 2 years or a fine

What else besides Section 315 may apply

A laser incident can touch several criminal offenses at once. If a crew member is injured in the eyes, bodily harm offenses are added. In particularly serious situations, investigators also examine whether an attempted homicide offense is present – for example, when someone deliberately and repeatedly blinds an aircraft at low altitude and accepts a crash as a possible outcome. Alongside the criminal proceedings, civil claims can come the offender’s way, for example for treatment costs or for operational consequences of an incident.

What a laser beam does in the cockpit

Most offenders underestimate the problem because the dot on the side of a house is tiny. In the sky, things look different.

The beam spreads out

A laser beam is not perfectly parallel. Over hundreds or thousands of meters, the dot becomes a spot of light several meters in diameter. It therefore doesn’t hit one eye but the entire cockpit window. The windshield panes are built from several layers, and scratches, dirt and moisture scatter the light further. The result is a brightly lit cockpit in which the crew can barely see anything for a moment.

Three effects on the crew

• Glare: As long as the light comes in, it overpowers instruments, displays and the view outside. Runway lighting and approach lighting vanish in the glare.
• Flash blindness: After intense exposure to light, vision stays impaired for some time – even when the beam is long gone.
• Afterimages: Colored spots in the field of view interfere with reading displays and judging distances, especially at night when the eyes are adapted to darkness.

On top of that comes the startle moment. A sudden, unexpected flash of light in the cockpit distracts, costs concentration and forces the crew to deal with something other than flying.

Eye damage is possible

With stronger devices, it is not just about temporary glare. Laser classes rate devices by how dangerous they are. The limits from the IEC/EN 60825-1 standard can be roughly summarized like this:

Laser class	Visible continuous-wave laser	Assessment
Class 1	very low power	safe under normal conditions
Class 2	up to 1 mW	conditionally eye-safe, protection is supposed to come from the blink reflex
Class 3R	up to 5 mW	risk when looking directly into the beam
Class 3B	up to 0.5 W	direct exposure dangerous to the eye
Class 4	above that	dangerous to eye and skin, also through scattered light

Even Class 2 is not as harmless as it sounds: a 2003 study found that the blink reflex, on which its classification is based, occurred in only a minority of test subjects (under 20 percent). In addition, online shops keep offering devices whose actual output is far above the stated class.

Why takeoff and landing are the critical phases

Laser attacks typically hit aircraft where they are easy to reach from the ground: on approach and shortly after takeoff, that is, at low altitude near airports. These very phases are among the most demanding of a flight.

On final approach, the crew often flies by instruments on the localizer beam – how that works is explained in the article ILS approach explained. Just before touchdown, the eyes shift outside to the runway and lighting. If a spot of light floods the cockpit exactly then, there is little room: the altitude isn’t enough to take your time, and the decision between landing and a go-around has to be made in seconds. After takeoff the workload is high too – gear, flaps, radio, heading.

The crew usually reports a laser incident immediately by radio. Air traffic control – in Germany the DFS Deutsche Flugsicherung – then informs the police so they can look for the starting point. Following aircraft are warned, which puts additional strain on operations.

How offenders are found

Many who point a laser at an aircraft believe they are invisible in the dark. The opposite is true: the beam is a glowing line that points straight to the location. Crews can often state quite precisely from which direction and in which area the light came. Depending on the situation, the police use patrols on the ground and helicopters in the search. Police helicopters are themselves repeatedly the target of such attacks – and can then follow the location directly from the air.

Witnesses on the ground add to that. Residents, walkers and, not least, spotters standing at the fence in the evening spot a laser beam in the sky immediately. A call to the police with a precise location is often enough to narrow down the starting point.

The legal situation in Austria and Switzerland

The neighboring countries also take action against laser pointers, though with different tools:

• Austria regulates laser pointers through its own laser pointer ordinance. Under it, only Class 1 and 2 devices may be placed on the market. Anyone who blinds an aircraft crew must also expect criminal prosecution; which provision applies depends on the individual case.
• Switzerland largely banned the import, sale and possession of laser pointers above the low classes in 2019 under its act on protection against hazards from non-ionizing radiation. There, too, blinding pilots is a crime.

If you spot abroad, the law of the respective country applies. An overview of typical differences is given in the article Spotting abroad.

What spotters should know

When it comes to lasers, plane spotters are not offenders but often the nearest witnesses. Especially if you stand under the approach path in the evening or at night – for example for long exposures like those described in the guide Photographing aircraft at night – you should keep a few things in mind.

No light sources toward the sky

A laser has no place in your camera bag – not even as a “pointer” to show others at the spot an aircraft. The same goes for powerful, focused flashlights or floodlights. A small light for the walk and for operating the camera is perfectly fine, as long as you point it downward. Anyone who handles lights in the direction of the approach quickly becomes suspect, even with no bad intent – similar to the topic of telephoto lenses and suspicion at the airport.

React correctly if you see an attack

Spotters as additional eyes around the airport – this idea also lies behind initiatives presented in the article Spotters as security partners. For drones, by the way, a similar pattern applies; what drone sightings at airports trigger is described in the piece Drone sightings at airports.

Stay calm if the police approach you

After a laser report, the police search the area around the airport. If you happen to be standing at the edge of a field with a tripod and camera at that moment, a patrol may stop by. Stay calm, explain what you are doing and feel free to show your pictures. How such checks work and what rights you have is explained in the article Police checks while spotting. If you saw something yourself, you are a valuable witness at that moment.

Typical excuses – and why they don’t hold up

What to watch out for

• Don’t bring a laser to the spot. There is no sensible use for one while spotting.
• Point lights downward. Red or dimmed light also protects your own night vision.
• Be especially careful under the approach path. What else to keep in mind there is covered in the article Spotting under the approach path.
• Educate younger fellow spotters. If you are out with teenagers, bring the topic up openly once – many simply don’t know the consequences.
• When in doubt, report it. Better one call too many to the police than a blinded cockpit.

The article Is plane spotting allowed? summarizes the basics on permitted locations at the airport fence, and the Code of conduct for plane spotters covers the scene’s unwritten rules.

A look at the spots

At big airports like Frankfurt Airport, Munich Airport or Hamburg Airport, the approaches run over residential areas and over places where people are out and about in the evening. Well-known spotter points like the Munich Airport visitors’ hill (Besucherhügel) or the Affenfelsen in Hamburg are close to runways and approach paths. It is exactly there that you see why spotters and airports share an interest: a spot only stays open and relaxed if no danger comes from it.

If you are out at night, you also benefit from recognizing aircraft by their lights – the article Identifying aircraft at night explains how. Tips for your own safety during night sessions are given in Spotting at night or alone.

Conclusion

A laser pointer is no plaything in the sky. The beam spreads, lights up the entire cockpit and hits crews in the phases of flight that tolerate distraction the least. German law reacts accordingly harshly: Section 315 StGB provides six months to ten years in prison for dangerous interference with air traffic, the attempt is punishable, and so is negligence. For spotters, that means: the laser stays at home, lights point downward, and anyone who sees an attack calls the police.
