Have you ever imagined what it would be like to be a pilot flying among high mountains, only to suddenly see the weather change completely in a matter of minutes? Fog descends, low clouds obscure the view, and steep cliffs appear everywhere. Scary, right?

Well, that’s the reality our pilots face every day, especially those serving in remote areas like Papua, Sulawesi, or Kalimantan. This is where one of the biggest threats in aviation lurks: CFIT, or Controlled Flight Into Terrain.

What is CFIT?
Simply put, CFIT is a plane crash that is actually in good condition and completely under control by the pilot, but suddenly crashes into a mountain or cliff. It’s like driving smoothly on a toll road, only to suddenly crash into a barrier wall due to a loss of focus. The plane wasn’t damaged, the engine was fine, and the pilot was fine—but navigation and situational awareness were.

According to data from the Flight Safety Foundation and ICAO (the international civil aviation body), CFIT (Cross-Flight Intermittent Threat) remains one of the leading causes of fatal accidents worldwide. And Indonesia, with its challenging geography, is clearly in the high-risk red zone.

Why Does This Happen?

Let me outline the factors that often lead pilots to fall into the CFIT trap:

First, the weather. Tropical regions like Indonesia are notoriously prone to changing weather. Suddenly, there can be thick fog, then heavy rain, then low clouds descend. In a matter of seconds, the pilot’s view out the window can be lost. When this happens, visual reference to the ground is lost. All that remains is white.

Second, situational awareness. This is the pilot’s ability to “be aware” of the aircraft’s position in relation to its surroundings. When the weather is bad, the only thing they can rely on are the instruments in the cockpit. However, if the instruments are inaccurate or the pilot is unfamiliar with them, it can be dangerous.

Third, outdated navigation. Many airports in mountainous areas still use conventional navigation systems like VORs or NDBs. Their accuracy is limited, especially if the terrain is complex. It’s like being told to navigate a narrow corridor with only a dim flashlight.

Fourth, operational pressure. This is the human factor. Sometimes pilots feel pressured—whether by mission, schedule, or company expectations—to land even when the weather is substandard. “Oh, the weather will improve soon,” or “Isn’t that possible?” These thoughts often lead to tragedy.

Technology Can Help, But…

Fortunately, aviation technology is now increasingly sophisticated. There’s something called Performance-Based Navigation (PBN). This satellite-based navigation system allows aircraft to follow a very precise flight path, even automatically “avoiding” mountains. Procedures like the RNP Approach are very helpful at mountainous airports.

Then there’s the EGPWS, or Enhanced Ground Proximity Warning System—like a chatty assistant in the cockpit. If the plane gets too close to the ground, this system will shout, “Land, land! Climb altitude! Climb altitude!” When I was a First Officer (FOO) on a plane, this warning always gave me goosebumps. But that’s precisely its purpose: to alert pilots and prompt them to take swift action.

Other technologies like ADS-B (Automatic Dependent Surveillance–Broadcast) are also crucial. In areas not covered by conventional radar, this system sends real-time position signals to air traffic controllers. So, even if the plane is in the middle of the Jayawijaya Mountains, ground personnel can still monitor it.

But remember, technology is just a tool. Without a skilled pilot with good decision-making skills, no matter how sophisticated the system, it’s useless.

The Human Factor Cannot Be Ignored

For me, the core of Cross-Flight Interferometer (CFIT) prevention lies in the pilot’s mind. Continuous training is crucial, especially regarding:

CFIT (Critical Flight Into Terrain) Awareness: knowing when a situation becomes dangerous.

– Use of modern navigation systems, including autopilot and FMS (Flight Management System).

– Most importantly: the courage to abort a landing or perform a go-around (turn around) if conditions prevent it. There’s no need to be embarrassed, no need to be afraid of being called a coward. It’s better to turn around than to have an accident.

Infrastructure Must Also Be Improved

This is where institutions like AirNav Indonesia, as navigation service providers, play a role. They need to continuously develop PBN procedures at mountainous airports, improve surveillance systems, and provide more detailed navigation maps. Pilots should not fly solely based on hunches and guesswork.

Conclusion: It’s a Shared Responsibility

CFIT is not just a pilot issue. It’s everyone’s concern: airlines must provide the best aircraft and training, AirNav must provide adequate infrastructure, and regulators must establish strict regulations. We must prevent accidents that occur due to ego or momentary pressure.

With a combination of advanced technology, well-trained pilots, and supporting infrastructure, we can reduce the risk of CFIT. Most importantly, all parties must realize: in Indonesia’s beautiful but pitfall-filled skies, there is no room for compromise when it comes to safety. Fly safely!
