Soon we’ll actually know where planes are as they fly over the ocean.

This month marks three years since Malaysia Airlines Flight 370 disappeared. On March 8, while flying from Malaysia to China, the plane deviated from its planned route, slipping from the range of radar somewhere over the Andaman Sea. MH370 and its 239 passengers likely crashed somewhere in the Indian Ocean, but even after a massive search effort, the black box was never found—leaving the tragedy permanently shrouded in mystery.

The frightening truth is that planes are essentially unaccounted for quite frequently. When you’re flying on a plane and the screen in front of you shows your position over an ocean or the poles, it’s likely that you, the passenger, know more about your plane’s location than Air Traffic Control does. But that is starting to change.
How it works ?
Pilots use GPS to track their plane’s position, but that doesn’t mean an air traffic controller can always find them.

Radar measures a plane’s location by sending out pings of radio waves and measuring how long it takes for the signals to bounce off the aircraft—but that only works if the aircraft is within the radar tower’s line-of-sight, with no mountains or other solid objects in the way. Radar doesn’t work over long distances, so the oceans are a big blind spot.
Starting about 15 years ago, air traffic control started using ADS-B ground stations. ADS-B, which stands for Automatic Dependent Surveillance-Broadcast, tracks the airplane’s position via GPS, and automatically broadcasts that information to Air Traffic Control as well as other planes.

ADS-B receivers are “about the size of a mini refrigerator,” says Capezzuto, and because they’re much easier to install in hard-to-reach places, they’re already improving airplane tracking. In fact, the Federal Aviation Administration likes them so much, they’re requiring all planes that fly through controlled airspace to be equipped with these broadcasters by January 2020.
However, ground-based ADS-B receivers have many of the same line-of-sight problems as radar, and under clear conditions, they only have a range of about 250 nautical miles at 28,000 feet.
“You don’t really have an option for surveillance in the ocean,” says Capezzuto. “Right now, air traffic controllers project where the aircraft should be, based on the flight plan or the pilot report, rather than reality. Deviations in the flight plan happen all the time.”

Putting the ADS-B receivers onto satellites removes the line-of-site problems, giving a birds-eye-view of planes flying across the entire globe. After receiving location data from the aircraft, Aireon’s 66 satellites will beam the information down to ground stations. The entire transaction takes about two seconds.

World’s Top 21 riskiest Travel Destinations – U.S. State Department’s Level 4 Advisories”

The US government provides travel advisories to warn its citizens about the safety and security circumstances in numerous places across the world. These recommendations are intended to assist travelers in making informed decisions and minimizing risks while abroad.

While many countries are typically safe to visit, the US Department of State advises exercising caution or avoiding travel altogether owing to a variety of concerns such as political instability, terrorism, and natural disasters.

Travel advisory levels are released by the U.S. State Department for over 200 countries worldwide. These levels are updated regularly depending on a range of risk factors, including health, terrorism, and civil unrest. Level 1 travel advisories advise taking standard precautions, while Level 4 advisories advise not going there.

As of October 23, over 10% of countries—21 in total—had a Level 4: “Do Not Travel” advice. The State Department states that in Level 4 countries, the United States government may have “very limited ability” to take action if travelers’ security or safety is in risk.

Places With a Level 4 Travel Advisory

Afghanistan: According to the State Department, the Central Asian nation is dealing with “armed conflict, civil unrest, crime, terrorism, and kidnapping.”

Burkina Faso: This West African country is plagued by crime, terrorism, and kidnapping. With little to no notice, schools, restaurants, and hotels may become targets of terrorist strikes.

Myanmar (formerly known as Burma): The main barriers to visiting this Southeast Asian nation are civil chaos and armed conflict.

Gaza: Due to the current conflict, US officials advise visitors to Israel, the West Bank, and Gaza to either postpone their plans or stay away.

Iran: All visitors are at danger for kidnapping and unjust detentions, but Americans are particularly vulnerable to “arbitrary arrest and detention.”

Iraq: The State Department bases its Level 4 designation on “terrorism, kidnapping, armed conflict civil unrest.”

Libya: Conflict between armed groups in Libya’s East and West has plagued the country since the fall of its dictatorship over a decade ago.

North Korea: is home to one of the longest-running dynastic dictatorships in history, and US passports are not valid for travel “to, in, or through” this nation.

Russia: The invasion of Ukraine, arbitrary law enforcement, and intimidation of American citizens by Russian government officials are among the factors that led to the country’s Level 4 travel recommendation.

South Sudan: Weapon assault, kidnapping, and crime are the main risk factors, with violent crime being widespread in the nation.

Sudan: Due to the continued turmoil in the nation, the United States withdrew its embassy from Khartoum in April 2023 and blocked its airspace.

Yemen: Yemen has six of the nine risk categories listed by the State Department: landmines, terrorism, civil instability, health hazards, and kidnapping.

Malawi: Level 2
The Department of State is warning visitors to Malawi to travel with extra caution in light of recent criminal activity and civil upheaval.

Bangladesh: Level 2
US residents who are in Bangladesh or intend to travel there should be especially careful because of the country’s high crime rate, terrorist attacks.

Saba: Level 1
The most recent alert states that visitors to Saba should take standard safety precautions.
