No, helicopters cannot fly over lava as it would be extremely dangerous for both the pilots and the helicopter itself. In addition to the intense heat of the molten lava, flying over it would also likely cause damage to the helicopter’s airframe due to the intense thermal updrafts created by the molten magma.
Airplanes, on the other hand, can fly over active volcanoes, as they are designed to withstand the extreme temperatures and pressures associated with flying over the heated terrain. However, they must adhere to certain safety protocols such as avoiding ash clouds and other hazards that volcanoes can produce.
Therefore, it is not advised for helicopters – or any other aircraft – to fly over active lava flows.

What are 2 possible volcanic hazards to aviation?
Volcanic hazards to aviation can include several potentially dangerous scenarios. Ash eruptions from an active volcano can create a blanket of ash in the air, blocking visibility and causing significant turbulence that can damage an aircraft.
Ash from a volcano can also damage the engine of an airplane, as the tiny particles can grind away and clog up the delicate machinary of the engine. In addition, pyroclastic flows from volcanoes, which are composed of fragmented lava, ash, and rock, are especially dangerous for aviation as they can easily reach temperatures of over 1,000oC and can travel at speeds over 100 mph.
Lastly, lahars, which are a type of slurrry composed of sediment and water, can significantly reduce visibility and also contain materials that can damage the engines of aircraft. When combined, these two potential volcanic hazards can make flying through an active volcano a difficult, and potentially dangerous, venture.
Can propeller planes fly through volcanic ash?
Propeller planes should not fly through volcanic ash because it can be hazardous to their engines. Volcanic ash is made of tiny pieces of rock and glass, along with other small particles. These particles can be abrasive and get sucked into the engine, which can damage or even destroy it.
Additionally, the ash can block air intakes, cool the engine, and cause engine stalls. Volcanic ash can even cause corrosion to the plane’s exterior, leading to further distress. No matter how well an aircraft is protected, even the smallest particles of ash can cause big problems for pilots.
Therefore, for safety reasons, it is not recommended for propeller planes to fly through volcanic ash.
How does a volcanic eruption impact airline operations?
Volcanic eruptions can have a significant impact on airline operations around the world. When a volcano is actively erupting, nearby airports can be forced to close due to the danger posed by the ash and debris in the air.
As a result, airlines must cancel or divert flights away from the area and re-route them to other nearby destinations. This can cause major delays and cancellations that have a ripple effect across the entire aviation system.
The ash and debris from an eruption can also cause significant damage to aircraft engines and engines exposed to the ash can malfunction while in flight. This can lead to an emergency landing or a forced return to the airport of origin.
Additionally, when an airspace near a volcano becomes restricted, airlines must be able to quickly recalculate aircraft routes to ensure they avoid the restricted airspace and comply with all regulations.
All of these factors can cause significant disruption to airline operations and greatly increase uncertainty as airlines try to keep up with changing airspace restrictions. Airlines must be proactive in responding to a volcanic eruption and continue to monitor their routes and airspace to ensure aircraft remain clear of possible eruptions and related airspace closures.
What should pilots do if they encounter volcanic ash?
If a pilot encounters volcanic ash in the sky, the safest option is for them to avoid it. Volcanic ash can be especially dangerous for aircraft due to its abrasive properties, and its effects on visibility, engines, and other aircraft systems.
If a pilot cannot avoid the ash cloud, they should immediately inform air traffic control and then follow the directions they receive. Generally, the pilot should climb to a higher altitude if they need to pass through the ash cloud, as the heavier ash residue will generally be found at lower altitudes.
The pilot should also update the engine instruments and have the crew monitor them for any sudden power drops. Additionally, the pilot should keep the engine throttles at normal levels to avoid any possible damage to the turbine blades.
Lastly, the pilot should close all windows, ventilators, and air conditioning systems to reduce the possibility of ash entering the airframe. Once the ash cloud has been passed, the pilot should review the engine instruments and the interior of the cockpit to make sure that there is no residual ash.
Taking these precautions will help to ensure a safe and successful flight.
Can planes fly over active volcanoes?
Yes, planes can fly over active volcanoes. Many planes fly over active volcanoes as a part of their normal flight paths on a daily basis. However, this isn’t always the case. In fact, some erupting volcanoes can be dangerous for planes to fly over and can even create hazardous conditions for the aircraft.
In order to protect aircraft from the potential hazards of flying over active volcanoes, pilots often rely on an active volcano watch. This is a system that monitors any changes in volcanic activity and alerts pilots if there is a risk of harm to aircraft in the area.
If the risk is thought to be too high, pilots can avoid flying over an active volcano.
In addition to being dangerous, flying over an active volcano can also be quite spectacular. Flying through an ash cloud created by a volcano can give passengers a unique view of an eruption and can even provide stunning views of lava flows.
It’s important to note that while planes typically are not prohibited from flying over an active volcano, it’s still best to use caution to ensure that everyone remains safe.
Can you fly in volcanic ash?
No, you cannot safely fly in volcanic ash. Volcanic ash contains tiny pieces of rock and glass which can cause significant damage and malfunction to an aircraft if it is ingested into the engines. In addition, the tiny particles of ash can cause turbulent air and visibility issues which would make flying unsafe.
The particles are incredibly light, making it difficult to detect with standard weather reports and forecasts, which is why volcanic ash can be so dangerous. Therefore, it is not recommended that planes fly in or near areas affected by volcanic ash.
Why is flying aircraft through an ash cloud not a good idea?
Flying an aircraft through an ash cloud is not a good idea because ash clouds typically contain airborne particulates from ash and volcanic rock particles that can impair the aircraft’s functions and safety.
When inhaled or ingested, volcanic rock ash particles can cause health problems for pilots, passengers and crew, and can even clog the engines or fill the air intakes, causi ng power loss or a decrease in thrust and engine performance.
Because of their high silica content, the ash particles can also corrode the engines, sensors and other aircraft components, possibly leading to catastrophic mechanical failure. Ash clouds also tend to reduce visibility, making it harder for pilots to navigate and land, and can be accompanied by large amounts of static electricity, lightning and wind shear, which can make flying even more hazardous.
Does volcanic ash shut down aircraft engines?
Yes, volcanic ash can shut down aircraft engines. Volcanic ash is comprised of very small particles of pulverized rock, minerals, and glass that can be carried in the atmosphere and breathed in by passengers and crew.
When these particles enter an aircraft’s engine, they can melt and then harden, creating a layer that blocks the airflow between the fan blades and the exhaust. This leaves the engine unable to cool itself, which can ultimately lead to the engine shutting down.
The ash also creates a foreign object debris that can have serious consequences on the structural integrity of the aircraft, leading to potential engine failure. In addition, the ash can also be abrasive to the moving parts of the engine, leading to premature wear and tear.
Large amounts of ash that are ingested can also cause significant damage to aircraft engines and potentially increase their chance of failure. To prevent engine failure due to volcanic ash, aircraft must take measures to avoid areas of ash clouds, as well as making sure that the aircraft has up-to-date certificates and inspections.
Would breathing in volcanic ash hurt?
Yes, breathing in volcanic ash could be damaging to your health. Volcanic ash contains particles of glass, quartz, and other minerals, all of which can be inhaled when they become airborne. Inhaling these particles can cause irritation to the nose, throat and lungs, leading to coughing, wheezing, and asthma-like symptoms.
Long-term exposure can even cause scarring of the lungs, coughing up of blood and difficulty breathing. Therefore, it is important to avoid breathing in volcanic ash, particularly if you suffer from pre-existing respiratory conditions such as asthma.
People in areas near active volcanoes should take extra precautions to protect themselves against volcanic ash. This usually entails staying indoors, using dust masks and closing windows and doors to prevent the ash from getting inside.
Staying informed about volcanic ash advisories and following any recommendations issued by local authorities can also help reduce the risk of health complications associated with volcanic ash.
Can a gas mask filter volcanic ash?
Yes, gas masks can be designed to filter volcanic ash. Gas masks are designed to filter out a range of particles, and this can include volcanic ash. Gas masks often have filters designed to protect against airborne particles and gases, and these filters can be designed to filter out volcanic ash.
Gas masks can be equipped with filters rated for very fine particles, so they can be effective at filtering out most of the ash particles. Additionally, because volcanic ash can contain toxic gases, having the right type of filter can be important in providing adequate protection.
For example, some gas masks come with activated carbon filters, which are designed to filter out organic compounds, such as those found in toxic gases. In conclusion, yes, gas masks can be designed to filter volcanic ash.
Can ashfall cause jet engine failure?
Yes, ashfall from volcanic eruptions can cause jet engine failure. Volcanic ash can enter a jet engine through its air intakes and cause damage to the engine’s blades and internal parts. The ash itself is abrasive, containing particles that are much harder than the metal components of the engine.
Even very small amounts of ash ingested into a jet engine can cause it to fail, as the ash can damage the internal parts of the compressor, the turbine and the combustion chamber. Moreover, the molten glass formed by the ash can lead to overheating and melting of the jet engine’s parts.
If a jet engine is exposed to a volcanic ash cloud, the engine must be thoroughly inspected before being operated to determine if repairs or replacement of parts is needed. Pilots should also take care to avoid flying in or near ash clouds, as even if no immediate failure is visible, long-term damage can occur and reduce the life expectancy of the engine.
What does volcanic ash block?
Volcanic ash is made up of tiny particles of rock and glass produced by volcanic eruptions. These tiny particles can spread for miles and have the potential to cause extensive damage and disruption. When the ash is spread over large areas, it can block roads, disrupt air and ground transportation, damage buildings, and contaminate water supplies.
The ash itself is abrasive and corrosive, and when mixed with water, it can form an acidic solution that can clog machinery, corrode metals, and disrupt communication systems. It is also an issue for aviation, as the ash can clog jet engines, causing them to stall or shut down.
Volcanic ash can also reduce visibility, making it more difficult for people to drive and engage in other forms of transportation. In addition, there is a health risk associated with the inhalation of volcanic ash because the particles are so small that they can penetrate deep into the lungs.
