Es una historia real y fascinante: algunos modelos del avión Jumbo Boeing 747-400 todavía utilizan disquetes de 3.5 pulgadas para actualizar sus sistemas de navegación críticos. Aunque tecnológicamente nos recuerde a la época de ordenadores clásicos de los 80 como el ZX Spectrum, el Amiga o los primeros IBM PC, esta práctica sigue vigente por razones estrictas de seguridad aeronáutica. [1] (Old Tech, Still Flying High: Floppy Disks in Modern Boeing 747s? Believe it or not, some Boeing 747 aircraft—especially older models like the 747-400—still rely on 3.5-inch floppy disks for critical software updates! Yes, the same floppy disks from the ’80s that hold just 1.44 MB of data. Why? Because in aviation, safety and certification come first. Once a system is certified for flight, airlines prefer to keep it unchanged unless absolutely necessary. Upgrading to newer data transfer methods can be costly, require recertification, and risk unforeseen issues. So, many airlines stick with what’s proven and reliable. How does it work? Technicians insert multiple floppy disks—sometimes every 28 days—to update navigation databases and system configurations. It’s a manual, time-consuming process, but it’s part of routine maintenance for those operating older 747s. While newer aircraft boast advanced digital systems, legacy technology still lingers in the skies, reminding us of aviation’s cautious approach to safety and innovation. #jhonesaintaerospaceengineer #trinc #highlightseveryone #everyoneシ゚ #fbnontrincfbnon #fbfriendstrincfbfriends #everyonehighlights #facebookreelsviral #viralreelschallenge #StarSender #AeronauticalEngineering #aerospaceengineering #safetyfirst | Jhone Saint), [2] (Retro pero real: aviones Boeing 747 usan antiguos disquetes para actualizar su sistema), [3] (Boeing 747 Runs Floppy Disk 5 3/5 like Amiga, IBM, PC MS-DOS - NeXuS23 Brøderbund)
Las claves de esta tecnología en pleno vuelo:
• La base de datos de navegación: Cada 28 días, los ingenieros de mantenimiento deben subir a la cabina del avión para actualizar de forma manual los mapas, rutas de vuelo, aeropuertos y frecuencias de radio. Para ello, introducen uno a uno un paquete de hasta 8 disquetes en una disquetera situada en la cabina. [1] (), [2] (Old Tech, Still Flying High: Floppy Disks in Modern Boeing 747s?

• No es obsolescencia, es seguridad: En la aviación comercial, si un sistema informático ha sido certificado como completamente seguro y estable, se prefiere no tocarlo. Rediseñar la cabina para usar puertos USB o conexiones inalámbricas obligaría a pasar por procesos de certificación regulatoria que costarían millones de dólares. [1] (When Boeing 747-400 pilots needed to update their navigation database as late as 2020, a technician would walk onto the flight deck with eight 3.5-inch floppy disks and feed them one at a time into a slot beside the captain's seat, because recertifying anything newer than the 1989 avionics would have cost hundreds of millions of dollars. - Make Tech Easier), [2] (The Boeing 747 Still Uses Floppy Disks For Software Updates: Here's Why - Jalopnik), [3] (Old Tech, Still Flying High: Floppy Disks in Modern Boeing 747s?

• Inmune a hackeos: Al no estar conectado a internet ni a redes externas, este sistema de disquetes cerrado es prácticamente imposible de acceso no autorizado a distancia. [1] (The Boeing 747 Still Uses Floppy Disks For Software Updates: Here's Why - Jalopnik)
Aunque los aviones modernos ya utilizan conexiones de fibra óptica o enlaces inalámbricos, la mítica "Reina de los Cielos" (el Boeing 747) mantiene un pie en el pasado informático para garantizar que sigamos volando seguros.
