Cockpits Go Paperless

Airline pilots, who fly some of the world’s most technologically advanced machines, have long relied on paper navigation charts and manuals, which clutter the cockpit and have to be lugged around in cases that can weigh as much as a small child. Now, however, airlines are catching up with the tablet era, reports The Wall Street Journal (June 27, 2013).

JetBlue Airways just received FAA clearance to provide its 2,500 pilots with Apple iPads that will store digital copies of the heavy paper manuals they refer to during flights. American Airlines said its 8,000 pilots had largely gone paperless now that the carrier has completed the rollout of its own iPad program. By storing manuals and navigation charts on iPads, American figures it has eliminated 3,000 pages of paper per pilot. In April, United started requiring its 10,000 pilots to carry iPads. Southwest started an iPad trial with 150 pilots this month and expects to expand it to an additional 550 pilots in the third quarter.

The volume of paper traditionally required by cockpit crews is almost overwhelming in the confines of a cockpit. American estimates that removing the bags from all its planes saves about 400,000 gallons of fuel annually, worth $1.2 million at current prices. One Alaska Airlines pilot said having the approach plates, arrival charts and runway diagrams available at the touch of a tablet is a lot quicker and more user-friendly. “It’s about information management, the human factors of managing charts,” he said. The change helps pilots be “safe and compliant” and helps the airline run a “better business.”

Wal-Mart vs. Amazon Logistics

Few have done better than Wal-Mart when it comes to retail logistics—the art of ordering, transporting, stocking and tracking merchandise, writes The Wall Street Journal (June 19, 2013).Wal-Mart pioneered a sophisticated hub-and-spoke distribution network which uses warehouses to service stores less than a day’s truck drive away so it could remove middlemen, quickly replenish shelves and reduce costs. At its distribution centers, scanning technology tracks merchandise as it flows at 6 miles per hour on 12 miles of conveyor belts onto trucks. Some items spend less than 45 minutes in warehouses.

Supply trucks crisscross the country and arrive daily at Wal-Mart’s more than 4,000 U.S. stores. Shipments are based on real-time data of shopper purchases, transmitted by the second as employees scan items at store checkouts. But with its e-commerce operations, which began in the late 1990s, Wal-Mart has been less exacting, instead relying on makeshift spaces carved out of store-serving warehouses and third-party operators to handle the load. Electronics ordered from Walmart.com are often delivered by companies like Ingram Micro which transport Apple tablets or Samsung phones to shoppers without ever going through Wal-Mart’s warehouses.

By contrast, Amazon has spent 15 years building its e-commerce network, with more than 40 U.S. warehouses within 35 miles of major cities. “As Amazon’s bets on infrastructure pay off, it can sell products at lower costs and puts even more pressure on other retailers,” says one industry expert. Wal-Mart now plans to spend roughly $430 million this year on e-commerce investments, including a logistics system tailored for Web orders. It is building distribution centers, but also will use stores as mini distribution centers. While logistics costs account for 3% of the price of an average “shopping basket” in stores, they make up 15% of the price of online orders.

Toyota Airbag Cuts Open Doors to Global Suppliers

Toyota has decided it no longer needs 50 kinds of airbags to protect drivers’ knees. Ten, the company says, ought to suffice. In one of Toyota’s biggest initiatives since 2009, reports Bloomberg (June 10, 2013), the carmaker is winnowing the number of parts it uses and increasing common components across models. The plan will cut both the time and cost for creating new models by as much as 30%. The automaker spent $9.6 billion in R&D last year.

In the past, Toyota focused on developing custom parts. It needed 50 types of knee-level airbags because seats for various models had different profiles. By standardizing “hip heights” across models, Toyota is reducing knee airbag variants by 80%. Last year, it had slashed radiators to 21 models from about 100. And it is reducing the number of cylinder sizes in its engines to 6 from more than 18. “From now on, Toyota will seek the compatibility of certain parts it uses with standard parts used by many automakers globally,” says the firm.

Toyota’s goal should make the company less vulnerable to supply disruptions by using parts from the largest manufacturers that can be substituted globally. The 2011 earthquake and tsunami in Japan forced Toyota to confront the complexity and risks of relying on thousands of suppliers, sub-contractors and sub-subcontractors making customized parts. The earthquake “really made us to look into our supply chain in great detail and see certain weaknesses there and look into things that needed to be fixed,” said Toyota’s spokesman.

International component makers such as Johnson Controls, Bosch GmbH and TRW Automotive are betting Toyota’s campaign will help them win contracts currently held by smaller Japanese companies. “This should mean more opportunities for global mega-suppliers with worldwide capacity and design expertise,” said one analyst.
