Aerospace NDT Simulator and Hands-On Practice in Dayton, Ohio

Few cities have a relationship with aircraft quite like Dayton. It is the hometown of the Wright brothers, the home of Wright-Patterson Air Force Base and the Air Force Research Laboratory, and a place where nondestructive evaluation has been studied as a science for decades through the laboratory’s materials and manufacturing research and its long partnership with the University of Dayton Research Institute. That heritage runs straight through the local workforce: machinists, aircraft maintainers, quality inspectors and NDT technicians who support military aviation, aerospace suppliers and the manufacturing base of the Miami Valley. Atlantis built the first-ever online practical NDT simulation portal for practice and hands-on experience, and Practical NDT brings that portal to Dayton. It is an immersive, 3D, game-like platform where you log in from a browser or app and carry out realistic inspections on virtual airframes, components, welds, bench specimens, process plant and storage tanks. Whether you are a new trainee, a working technician keeping rare-defect recognition sharp, or a Level III who needs to benchmark a team, it gives you somewhere to practise that does not depend on hangar access or specimen availability.

Why Hands-On NDT Practice Matters in Dayton’s Aerospace Sector

Aerospace inspection is a discipline where the consequences of a missed indication are unusually severe and the defects you are hunting are unusually small. A fatigue crack growing from a fastener hole, corrosion hiding under a lap joint, or a crack at a fillet radius on a fitting might be only a fraction of a millimetre long when it first becomes detectable. Finding it depends on technique discipline: the right probe, the right frequency, a proper calibration on a representative reference standard, consistent scan paths and the judgement to tell a real signal from edge effect or lift-off. Those skills are perishable. Technicians who support aircraft maintenance often work through long periods of routine inspections where nothing is found, and then must perform perfectly on the one occasion when something is there. Meanwhile, access to real aircraft for training is limited by operational schedules, security and the simple fact that aircraft on the ground for maintenance are there to be fixed, not practised on. Reference standards with realistic cracks are costly and closely controlled. Dayton’s workforce also turns over as military members separate from service and move into civilian aerospace, manufacturing and inspection jobs, often bringing strong experience in one method but limited exposure to others. Practical NDT addresses all of these pressures. It provides a place where a technician can rehearse eddy current and ultrasonic techniques on airframe and component geometry as often as needed, see the kinds of flaws that are rare in daily work, and receive immediate feedback on coverage and detection. It also supports the growing number of people moving between aerospace and industrial NDT in the Miami Valley, where a technician might spend one contract on aircraft components and the next on welds or pressure equipment at a manufacturing plant.

The Aircraft Hangar Environment and Other Workplaces for Miami Valley Technicians

Practical NDT is built around five workplace environments, and for Dayton the Aircraft Hangar is the anchor. It contains 54 jobs focused on airframe and component inspection, where you work around realistic aircraft structure and parts instead of flat test plates. Here the emphasis is on the methods aerospace relies on most heavily: eddy current for surface and near-surface cracking and for conductivity checks, ultrasonic testing for thickness, bond and internal flaw detection, penetrant for surface-breaking defects on non-ferromagnetic components, magnetic particle for ferromagnetic parts, and visual inspection as the first line of defence. The NDT Lab environment, with 52 jobs, is where the fundamentals are built: calibrating on reference blocks, setting gates and sensitivity, and learning how a signal changes with probe angle and frequency. The Welding Workshop, also with 52 jobs, matters in Dayton because the region’s manufacturing base includes fabricated structures, ground support equipment, tooling and industrial equipment in which weld quality is critical. The Oil & Gas Site environment, with 73 jobs, and the Storage Tank environment serve technicians who work on fuel handling, utility, power and process equipment around the region, including fuel storage that supports aviation operations. The mix matters. Many Dayton inspectors are not purely aerospace or purely industrial; they move between sectors as contracts change. A platform that lets them stay current on hangar work while also practising weld and plant inspection is a better fit for the real local job market than one that treats aerospace as a separate world.

Methods You Can Practice: Eddy Current, Ultrasonic Testing Simulator and Phased Array Simulator

Practical NDT covers twelve methods. For a Dayton aerospace technician the electromagnetic group is often the starting point. Eddy current scenarios let you choose probes, set frequency and phase, null on a reference standard and scan for cracks around fastener holes, edges and radii, learning to distinguish crack signals from lift-off, edge effect and changes in conductivity. MFL is also included, primarily for tank floor screening. The surface methods are penetrant testing, magnetic particle testing and visual testing, each with realistic process steps and interpretation. The volumetric methods include conventional contact ultrasonic testing, phased array UT, time-of-flight diffraction and radiography. The ultrasonic testing simulator teaches you to calibrate, select angle and frequency, scan systematically and size indications; scoring rewards complete coverage as well as detection, which reflects how aerospace procedures are written. The phased array simulator shows how sectorial and linear scans reveal indications that a single-angle probe can miss, and helps technicians understand focal laws, beam coverage and encoded data before they sit in front of an expensive instrument. TOFD provides practice in diffraction-based sizing. RT scenarios cover exposure setup, image quality indicators and interpretation, all without radiation exposure. Three specialised methods complete the list: LRUT guided-wave screening for piping, IRIS internal rotary ultrasonic testing for heat exchanger and boiler tubes, and positive material identification for alloy verification. Aerospace technicians may not use IRIS or LRUT day to day, but the breadth means that someone moving into industrial work, or supporting a base’s utility plant or fuel systems, can build familiarity before their first job. Thirty-three guided lessons teach the theory and technique behind each method before the job library tests it.

Built for Every Skill Level on a Dayton Inspection Team

The platform is designed for three distinct users. New trainees start with guided fundamentals. They learn what each instrument control does, why calibration matters, how a crack indication differs from geometry and how to document what they find. The scenarios become more demanding as they succeed, and instant feedback makes errors part of learning rather than a failure in front of a customer. This is useful for people entering the field from technical colleges, from aircraft maintenance roles or from other manufacturing jobs in the Miami Valley. Working technicians use Practical NDT to stay sharp. In aerospace, the problem is rarely that a technician has forgotten how to use eddy current; it is that they have not seen a real crack signal in months, and the first one they see on a real part must be recognised immediately. Scenario sets built around rare defects keep that recognition alive between assignments, and a short refresher before a new inspection program starts helps technicians adjust to different geometry, materials or procedures. Level IIIs and team leads get a way to build and assign scenario sets, compare results objectively and identify coverage gaps across a team. That matters in any environment where auditors and customers expect evidence that personnel are competent, and it gives leads an objective basis for deciding who needs additional formal training. Difficulty adapts to performance, so a highly experienced technician is not wasting time on basic scenarios and a newcomer is not overwhelmed. Everyone uses the same platform, but each person gets a path that fits their stage.

NDT Practical Exam Preparation That Complements Formal ASNT Training

Practical NDT is a practice and readiness tool. It does not certify anyone, it does not grant a Level I, II or III, and it does not replace the practical examination on real specimens required by ASNT SNT-TC-1A and the employer’s written practice. Under SNT-TC-1A, certification remains the employer’s responsibility and depends on documented training, documented experience and written and practical examinations. Aerospace employers and their customers may also impose additional requirements through their own specifications and qualification programs, and a Dayton technician should always follow what their employer’s written practice says. What the simulator does is make the path to that practical exam smoother. Someone who has already calibrated on a virtual reference standard, scanned a fastener hole with eddy current and sized an indication with ultrasonics will approach the real exam with confidence and fewer basic mistakes. That is why Practical NDT is designed to work alongside Atlantis NDT training and certification programs, which provide the classroom instruction, real-equipment hands-on work and examination preparation that certification requires. The scenario library was designed by Anoop Rayavarapu, ASNT NDT Level III and founder of Atlantis NDT, who also leads Atlantis training, so practice scenarios mirror the skills taught in class. The best comparison is flight training: simulator hours are valuable and widely used, but nobody earns a licence without flying the real aircraft for an examiner. In the same way, the practical exam on real specimens remains the standard, and the simulator is the preparation that makes that exam a demonstration of skill rather than a first encounter.

Dayton’s NDE Heritage and Industrial Landscape

Dayton’s connection to nondestructive evaluation runs unusually deep. The Air Force Research Laboratory’s Materials and Manufacturing Directorate at Wright-Patterson includes a nondestructive evaluation branch that has worked for years with the University of Dayton Research Institute on inspection research, including eddy current imaging and other advanced techniques used to assess aging aircraft structure. Wright-Patterson is also home to the Air Force Life Cycle Management Center, which oversees acquisition and sustainment of aircraft and systems, and that sustainment focus creates steady demand for people who understand inspection and structural integrity. The National Museum of the United States Air Force, located on the base, is a reminder of how long the region has been at the center of American aviation. Beyond the base, the Miami Valley has a diverse manufacturing economy built on automotive supply, precision machining, tooling, industrial equipment and aerospace components, much of it spread across Montgomery, Greene, Miami and Clark counties. To the north, one of Ohio’s major automotive engine plants in Anna is being retooled for electric vehicle components, and a large battery cell joint venture is under construction southeast of the region near Jeffersonville, both within commuting distance for Dayton technicians. Utilities, fuel terminals and industrial plants add further demand for weld, corrosion and tank inspection. The result is a job market where an inspector may spend part of a career on aerospace components and part on industrial equipment. Practical NDT is built to support that kind of movement by covering aircraft, welds, lab specimens, process plant and tanks within one platform, so technicians can build and maintain range as well as depth.

Radiography, Radiation Safety and Regulation in Ohio

Radiography is widely used on aerospace castings, welds and assemblies, and it is also the method where the argument for practising virtually is strongest. Ohio is an NRC Agreement State, so the Ohio Department of Health administers licensing and inspection of radioactive materials, including gamma sources used in industrial radiography, and also regulates industrial X-ray equipment. Radiography in the state must comply with requirements covering licensing, radiographer and assistant qualification, surveys, personnel monitoring and restricted areas. Military installations and federal facilities may have their own additional controls. Learning on live sources means dose, restricted areas and interruptions to other work. Practical NDT allows trainees to learn exposure geometry, source and film placement, image quality indicators and interpretation without any radiation. In RT scenarios you plan the shot, set up the technique and then evaluate the image for gas porosity, shrinkage, inclusions, cracks, incomplete fusion and other discontinuities depending on the component. You can repeat the same exposure with different parameters to see how geometric unsharpness and contrast change, something that would be wasteful and time-consuming with real sources. This does not replace the regulatory training, supervised experience and qualification required in Ohio before someone performs radiography, and nobody should treat simulator practice as permission to work with sources. It is a way to make sure that when a trainee does begin supervised radiography, they already understand what they are trying to achieve and can recognise what a good radiograph looks like. For a Dayton employer, that means less time spent correcting basic technique errors in the field and a safer introduction to radiographic work.

Bringing Practical NDT to Your Dayton Team

Most Dayton organisations begin with a demo tailored to their work. For aerospace suppliers and maintenance providers that usually means the Aircraft Hangar and NDT Lab environments with a focus on eddy current, ultrasonic and penetrant scenarios. For manufacturing and fabrication companies the Welding Workshop becomes central, and for utility and fuel handling operations the Oil & Gas Site and Storage Tank environments are the best fit. Atlantis built the first-ever online practical NDT simulation portal for practice and hands-on experience, and during a demo we show how scenario sets can be assigned, how results appear to a Level III and how the platform fits alongside formal training. Access is through a browser or app, so there is no specialist hardware to buy and no training room to set up. Pricing is never published. Like every Atlantis product, Practical NDT is positioned as affordable, accessible and fully customisable, and quotes are provided on request after we understand your team size and training needs. Technical colleges and training providers in the Miami Valley can also discuss how the platform might support students before they reach real equipment. To get started, request a Practical NDT demo for your Dayton team. If you are planning a larger program or want to combine simulator practice with formal certification training, contact Atlantis with details of your work, or email info@atlantisndt.com.

Frequently Asked Questions About Practical NDT in Dayton
