ForeFlight, the iPad, and How the Electronic Flight Bag Rewired the General Aviation Cockpit

SUMMARY: How the iPad and apps like ForeFlight became essential GA avionics - plus the heat, battery, and complacency risks every pilot should manage.

The electronic flight bag (EFB) - typically an iPad running an app like ForeFlight - has become one of the most important pieces of avionics in general aviation, despite being a consumer device never designed to fly. It gives pilots real-time GPS position, in-flight weather, and every chart in the country in a device that weighs about a pound. But because it’s built for the couch, not the cockpit, it brings risks paper never did: heat shutdowns, single-point battery failure, and skill-eroding complacency.

What Is an Electronic Flight Bag (EFB)?

An electronic flight bag is any electronic device that replaces the paper pilots used to carry. And it was a lot of paper.

Fly cross-country in 1995 and your flight bag held folded sectional charts, an airport facility directory as thick as a phone book, a binder of approach plates, a plotter, an E6B, a flashlight, and a paper log.

Today, many pilots carry an iPad and a backup battery. That’s the entire shift, and it’s a dramatic one.

Where Did the EFB Actually Come From?

The EFB revolution didn’t come from an avionics company. It came from Cupertino.

When Apple released the first iPad in 2010, it was a media device for reading magazines and watching video. Nobody in that room was thinking about a Cessna 172 at 8,500 feet on a bumpy afternoon.

But a few small software companies saw the glass screen, the built-in GPS chip, and the all-day battery, and recognized a moving map - every chart you’d ever need, in your lap, with your own airplane painted on top of it.

The most famous of those companies is ForeFlight, founded by Tyson Weihs and Jason Miller. They had a flight-planning app running on the iPhone before the iPad even existed; when the bigger screen arrived, the whole concept clicked. Boeing acquired ForeFlight in 2019.

ForeFlight was never alone. Garmin Pilot came from the avionics world itself, and FltPlan Go, iFly, and others round out a full ecosystem. Within just a few years of the first iPad, surveys showed the majority of GA pilots had moved to a tablet in the cockpit - not because airlines mandated it, but because individual pilots decided the paper wasn’t worth the weight.

What Does a Tablet Give You That Paper Couldn’t?

Three things, in order of impact.

1. Position awareness. A paper sectional tells you where the airport is, not where you are - you figure that out with a clock, a heading, and landmarks. The tablet’s internal GPS puts a moving airplane symbol on the chart in real time. For a low-time pilot on a hazy day, that’s the difference between confident and lost.

2. In-flight weather. Pair the tablet with a portable ADS-B receiver - a Stratus or a Sentry - and it pulls in the free government weather broadcast (Automatic Dependent Surveillance–Broadcast, or ADS-B). Radar mosaic, METARs, winds, and temporary flight restrictions get painted right onto your map. Weather you once had to imagine from a briefer’s voice, you can now watch move.

3. Everything else, weightless. Every approach plate, every airport diagram, your logbook, weight and balance, performance numbers, and checklists live in one device - kept current with a download instead of a mail subscription and a pair of scissors.

This is genuinely one of the best safety tools to reach the light-airplane cockpit in a generation.

What Are the Downsides of Flying With a Tablet?

A consumer tablet doing an aviation job carries baggage a paper chart never did.

Problem one: heat. Park on a July ramp with the tablet in direct sun on the glareshield, fire up for taxi, and the screen goes black with a thermometer icon. The iPad has overheated and shut down to protect its battery. That’s not a bug - it’s a consumer product behaving exactly as designed, at the worst possible moment.

Problem two: single point of failure. When all your charts live on one device, that device becomes critical. If the battery dies, it overheats, or the app locks up, you lose your charts, position, plates, and weather all at once. Paper never ran out of electrons over unfamiliar terrain.

Problem three: complacency. The moving-map symbol is so reassuring that it can quietly erode the skills underneath it - pilotage and dead reckoning, the habit of looking out the window and knowing where you are without being told. When the magenta line is always there, some pilots stop practicing for the day it isn’t.

How Should Pilots Manage EFB Risk?

The answer the community landed on is redundancy. You’ll hear it phrased as never fly with a single EFB.

Carry a second device - a phone running the same app - plus a backup battery, and for many pilots a paper chart or at least a printed plate for the destination in the seat pocket. Belt and suspenders. The tablet is a spectacular primary tool and a terrible only tool.

The FAA noticed all of this and wrote guidance on EFB use, especially for commercial operations, leaning hard on the same point: have a backup and have a plan for when the screen goes dark. Airlines carry two independent tablets, cross-checked, for exactly this reason. The physics of a lithium battery on a hot day doesn’t care whether you’re flying a Boeing 737 or a Piper Cherokee.

How Are Tablets and Panel Avionics Coming Together?

For years the EFB and the installed avionics lived in separate worlds - you’d program your route twice, once on the panel and once in your hand.

That’s changing fast. Modern panel-mount systems now share data with the tablet over a wireless link. Plan on the couch, walk to the airplane, and send the whole route straight into the panel. Traffic and weather from the installed system can appear on the tablet, and the flight plan flows both directions.

The honest tradeoff: it’s convenient, but it’s one more place for something to go wrong. Every wireless link can drop, and every automatic sync is a chance for two systems to disagree about where you’re going. Understand the automation, know which box is the source of truth, and be ready to fly the airplane when the clever stuff stops being clever.

Why the EFB Matters Beyond the App

The deeper lesson is bigger than any single product. General aviation has spent decades waiting on the certified world, where new avionics move slowly because certification is expensive and careful - as it should be.

The tablet snuck in through a side door. It wasn’t certified as flight-critical; it was classified as supplemental situational-awareness gear, and that lighter regulatory footing is exactly why it could evolve at consumer speed - a software update every few weeks instead of a hardware cycle measured in years.

It’s the same spirit that put glass panels in experimental aircraft long before they were affordable in certified ones. The EFB is that idea again, running on hardware Apple built for something else entirely.

Key Takeaways

• The EFB - usually an iPad with ForeFlight, Garmin Pilot, or a competitor - replaced a bag full of paper charts and became core GA avionics after the 2010 iPad launch.
• ForeFlight, founded by Tyson Weihs and Jason Miller, was acquired by Boeing in 2019; it started as an iPhone app before the iPad existed.
• The tablet’s biggest wins are real-time GPS position, ADS-B in-flight weather (via a Stratus or Sentry receiver), and carrying every chart weightlessly.
• The real risks are heat shutdowns, single-point battery failure, and complacency that erodes pilotage and dead reckoning.
• The fix is redundancy - a second device, backup battery, and paper backup - an approach the FAA endorses and airlines follow with two cross-checked tablets.
