While others still fumble with floppy disks and bulky hardware, your fleet runs on the most ridiculously compact ARINC615 data loader ever made. 45mm. Nothing else comes close.
A 30-second overview of what it does and which aircraft it loads.
The nanoPDL is a compact ARINC 615 portable data loader (PDL) designed and manufactured by DTech SIA. Maintenance teams use it to upload LRU operational software and databases to Airbus A320, A330 and A340 and Boeing 737 aircraft over a standard ARINC 615 (and ARINC 603) interface.
Measuring just 45 × 45 × 45 mm and weighing 1.3 kg as a complete kit, it replaces bulky legacy data loaders and floppy-disk media with fast, reliable USB flash loading. In practical terms: one pocket-sized device loads avionics such as the FMGC, ATSU, FDIMU, DLRB and FMC across a mixed Airbus and Boeing fleet — no proprietary media, no suitcases, no floppy disks.
Every other portable data loader is a compromise. This isn't.
USB flash storage. Instant transfers. Multiple databases on one stick. Welcome to this century.
45 x 45 x 45 mm. That's not a typo. The entire data loader is smaller than a Rubik's cube.
No more corrupted media, no more crossing fingers during transfers. Rock-solid reliability, every time.
One device for your entire mixed fleet. Airbus, Boeing — nanoPDL doesn't play favorites.
Hand it to any technician. They'll master it before the end of their first break. We made it stupidly simple on purpose.
Machined aluminum body. Peli™ case. Designed for hangars, not office desks. Drop it. It doesn't care.
Obsessively engineered. Unapologetically compact.
Multiple LRU databases on a single USB stick. Select what you need, plug in, load. No special media, no proprietary formats, no nonsense. Your PC talks to your aircraft — through a device that fits in your palm.
Other data loaders come in suitcases. Ours comes in a pocket. The nanoPDL is a 45mm aluminum cube in a rugged Peli™ 1120 case — the entire kit weighs 1.3kg. Store it onboard, carry it anywhere, forget it's there until you need it.
FMGC, ATSU, FDIMU, DLRB, FMC — the nanoPDL speaks every dialect. ARINC615 and ARINC603 adapter cables make it the one device your entire maintenance team actually wants to use.
We'll let the specs do the bragging.
It's 2026 and some airlines still load avionics software from floppy disks. Let that sink in. We built a 45mm cube that replaces the whole circus.
Ditch the FloppyAirlines and MROs who decided they're done with the old way.
Everything you might want to know about the nanoPDL and ARINC 615 data loading.
The nanoPDL is a portable data loader (PDL) designed and built by DTech SIA. It loads operational software and databases into aircraft line-replaceable units (LRUs) over an ARINC 615 data bus. At just 45 × 45 × 45 mm it is one of the most compact ARINC 615 data loaders available, replacing bulky legacy loaders and floppy-disk media.
ARINC 615 is the industry standard for loading software and databases into aircraft avionics over the ARINC 429 data bus. It has gone through several revisions — 615-3 and 615-4 are the ones you meet on Airbus A320-family and Boeing 737 flight lines. A portable data loader (PDL) is the handheld unit that performs that transfer, replacing the 3½-inch floppy drives originally specified. The nanoPDL implements ARINC 615-4 and ARINC 603, with adapter cables for both. ARINC 615A is a separate Ethernet-based standard rather than a newer revision of 615, and is not backward compatible with 615 hardware — the nanoPDL does not support 615A today, and support is in development.
The nanoPDL supports both Airbus and Boeing fleets, including the Airbus A320 family, A330 and A340, and the Boeing 737. A single device works across a mixed Airbus and Boeing fleet.
The nanoPDL loads common loadable LRUs including the FMGC, ATSU, FDIMU, DLRB and FMC, using ARINC 615 and ARINC 603 adapter cables.
The data loader itself measures 45 × 45 × 45 mm — roughly the size of a Rubik's cube. The complete kit, including the rugged Peli™ 1120 case and cables, weighs just 1.3 kg.
Yes. The nanoPDL uses USB flash storage instead of floppy disks, so a technician can store multiple LRU databases on a single USB stick and load them quickly and reliably, without proprietary media.
The nanoPDL is designed and manufactured directly by DTech SIA, an avionics company based in Latvia, and is shipped worldwide. To request a quote, email dtech@dtech.aero, call +371 278 45 027, or use the contact form below.
