Item 1. Description of Business

(a)   Business Development 

      Environmental Tectonics Corporation ("ETC" or the
"Company"), a Pennsylvania corporation, incorporated in 1969, is
principally engaged in the manufacture and sale of products used
in controlling, modifying, simulating and measuring environmental
factors such as temperature, humidity, pressure, and vacuum. 
These products include aircrew training systems, sterilizers,
environmental and other products which involve similar
manufacturing techniques and engineering technologies.

      Since February 28, 1997, there has been no material change
in the Company's mode of conducting business.

(b)   Business of the Company   

      The company operates in two primary business segments,
Aircrew Training Systems and Process Simulation.

      Aircrew Training Systems.  This segment includes four
primary product groups.

      The Company's aircrew training devices are used for medical
research, advanced flight training, and for the indoctrination
and testing of military and commercial pilots.  The major devices
sold in this product area are commercial flight simulators, high
altitude decompression chambers, hyperbaric (high-pressurized
oxygen) chambers, night vision trainers, water survival training
equipment, disorientation training equipment, human centrifuges,
and ejection seat trainers.  The Company provides operation and
maintenance services for installed equipment it manufactures as
well as equipment produced by others.

      The Company's entertainment products consist of motion-based
simulation rides.

      The Company's Disaster Management Systems line includes
real-time interactive training programs that allow instruction on
various disaster situations.

      The Company's Hyperbaric line includes monoplace and
multiplace chambers for decompression and wound care
applications. 

      The aircrew training system class of products as a whole
represented 75% and 61% of consolidated revenues of the Company
for the years ended February 27, 1998 and February 28, 1997,
respectively.

      Process Simulation.  This segment also includes two primary
product groups:  

      Sterilizers.  The Company manufactures steam and gas
sterilizers.  Steam sterilizers are used for hospital, medical
research laboratory, and industrial purposes.  Gas sterilizers
are used for the sterilization of packaged products such as food,
spices, pharmaceutical, and disposable and reusable medical
devices.  The Company's sterilizers range in price from
approximately $25,000 to over $1,000,000, and in chamber size
from three cubic feet to over 4,000 cubic feet, although the
Company concentrates on marketing the larger custom-designed
sterilizers to the pharmaceutical and medical device industries. 
The sterilizer class of products represented 19% and 28% of
consolidated revenues of the Company for the years ended
February 27, 1998 and February 28, 1997, respectively.

      Environmental Systems and Other Products.  The Company's
environmental systems business consists of the design and
fabrication of sampling and analysis systems, and test equipment
and systems used in measuring, monitoring and testing air
pollution.  The Company also designs and manufactures
environmental simulation systems to meet specific needs of its
customers.  The simulation systems generally consist of an
enclosed chamber with instrumentation and equipment which enable
the customer to control and modify such environmental factors as
temperature, pressure, humidity, wind velocity and gas content to
produce desired conditions.  These products include controlled
air systems for automotive companies and environmental chambers

      Sales of these products were 6% and 11% of consolidated
revenues of the Company for the years ended February 27, 1998 and
February 28, 1997, respectively.

      The Company also provides repair and maintenance service for
its own and other manufacturers' equipment.

Marketing

      The Company currently markets its products and services
primarily through its officers and employees.  At February 27,
1998, approximately 16 employees were committed to sales and
marketing functions.  The Company uses branch offices in the
United Kingdom, the Middle East, and Asia as well as the services
of approximately 100 independent sales organizations in seeking
foreign orders for its products.

Product Development

      New products and improvements in existing products are being
continually developed in response to inquiries from customers and
to management's determination that particular products should be
produced or significantly improved.  Although the Company does
not have a separate research and development group, there are a
few technical personnel whose main activity is the development
and integration of new technologies into our existing products. 
These personnel include the Vice-President of New Product
Development whose additional activity is the introduction of
product extensions and new applications of existing technology.

      The Company is currently focusing its product development
efforts in the aircrew training systems segment, with a
particular emphasis on enhancing the related control systems and
software graphics, and exploring commercial possibilities.  The
Company's product development efforts will be focused on two
areas:  

      -     Disaster Management Simulation.  The Company in Fiscal
            1997 completed a Firefighting Command and Control
            System and Trainer for a foreign governmental agency.
            Product extensions into other disaster situations are
            currently being investigated.

      -     Gyro-Product Line.  These products address the need for
            a relatively low cost flight and spatial disorientation
            trainer. 

      The Company reported research and development costs of
approximately $148,000 and $167,000 for the years ended
February 27, 1998 and February 28, 1997, respectively.  However,
the majority of the Company's research and development efforts
are not separately identified and recorded.  Instead, they are
expressed as part of project job costs in the cost of sales.

Supplies

      The components being used in the assembly of systems and the
parts used to manufacture the Company's products are purchased
from equipment manufacturers, electronics supply firms and
others.  To date, the Company has had no difficulty in obtaining
supplies.  Further, all raw materials, parts, components, and
other supplies used by the Company in the manufacture of its
products can be obtained at competitive prices from alternate
sources should existing sources of supply become unavailable.

Patents and Trademarks

      The Company has no patents or trademarks which it considers
significant to its operations, except a patent on the GYROLAB
Spatial Disorientation Trainer which expires in December 2004.

Customers

      In the current year and recent past, it has been the
Company's experience that a substantial portion of sales are made
to a small number of customers that vary within any given year. 
The Company's business does not depend upon repeat orders from
these same customers.  Sales of aircrew training systems are made
principally to U.S. and foreign governmental agencies.  Sales of
sterilizers and environmental systems are made to commercial and
governmental entities worldwide.

      In fiscal 1998, the Company's major customers included the
United Kingdom, Japan and the U.S. Government, which accounted
for $5,492,000, $3,266,000 and $2,936,000 of the Company's sales,
respectively.  These governmental entities do not have any
relationship with the Company other than as customers.

Foreign and Domestic Operations and Export Sales

      During the years ended February 27, 1998 and February 28,
1997, approximately $2,936,000 (10%) and $2,082,000 (10%),
respectively, of the Company's net revenues were attributable to
contracts with agencies of the U.S. Government or with other
customers who had prime contracts with agencies of the federal
government.

      During the years ended February 27, 1998 and February 28, 
1997, approximately $17,490,000 (60%) and $15,422,000 (70%),
respectively, of the Company's net revenues were attributable to
export sales or sales for export.  (See Note 10 to the Company's
consolidated financial statements incorporated herein by
reference to the Annual Report.)  On export sales, customers'
obligations to the Company are secured by irrevocable letters of
credit based on the credit worthiness of the Customer.

      The Company does not believe that the distribution of its
sales for any particular period is necessarily indicative of the
distribution expected for any other period.

      A large portion of the Company's sales are under long-term
contracts requiring more than one year to complete.  The Company
accounts for sales under long-term contracts on the percentage of
completion basis.  See Notes 1 and 3 to consolidated financial
statements.

      The Company's U.S. Government contracts contain standard
terms permitting termination for the convenience of the
Government.  In the event of termination of such contracts, the
Company is entitled to receive reimbursement on the basis of work
completed (cost incurred plus a reasonable profit), recording the
amounts anticipated to be recovered from termination claims in
income as soon as those amounts can be reasonably determined
rather than at the time of final settlement.  All costs
applicable to a termination claim are charged as an offsetting
expense concurrently with the recognition of income from the
claim.

Backlog

      The Company's sales backlog at February 27, 1998 and
February 28, 1997 for work to be performed and revenue to be
recognized under written agreements after such dates was
approximately $27,523,000 and $25,800,000, respectively.  In
addition, the Company's training and maintenance contracts
backlog at February 27, 1998 and February 28, 1997 for work to be
performed and revenue to be recognized after that date under
written agreements was approximately $2,925,000 and $5,100,000,
respectively.  Of the 1998 backlog, approximately $29,135,000 is
under contracts for aircrew training systems and maintenance
support.  Approximately 60% of the 1998 backlog is expected to be
completed prior to February 26, 1999.

Competition

      The Company's business strategy in recent years has been to
seek niche markets in which there are not numerous competitors. 
However, in some areas of its business the Company competes with
well-established firms, some of which have substantially greater
financial and personnel resources.

      Some competitor firms have technical expertise and
production capabilities in one or more of the areas involved in
the design and production of physiological flight training
equipment, environmental systems, and other specially designed
products, and compete with the Company for this business.  The
competition for any particular project generally is determined by
the technological requirements of the project, with consideration
also being given to a bidder's reliability, product performance,
past performance, and price.

      The Company faces particularly intense competition from a
number of firms in the sale of hospital sterilizers but faces
less competition in the sale of the larger custom-designed
industrial sterilizers.

      The Company believes that it is a significant participant in
the markets in which it competes, especially in aircrew training
systems in which the Company believes it is a principal provider
of this type of equipment and training in its market area.

Compliance with Environmental Laws

      The Company has not incurred during fiscal 1998 nor does it
anticipate incurring during fiscal 1999 any material capital
expenditures to maintain compliance with Federal, state and local
statutes, rules and regulations concerning the discharge of
materials into the environment, nor does the Company anticipate
that compliance with these provisions will have a material
adverse effect on its earnings or competitive position.

Employees

      On February 27, 1998, the Company had 185 full-time
employees, of whom 5 were employed in executive positions, 29
were engineers, engineering designers, or draftpeople, 47 were
administrative (sales, accounting, etc.) and clerical personnel,
and 104 were engaged principally in production and operations.

Item 2. Description of Property

      The Company owns its executive offices and principal
production facilities located on a 5-acre site in the County Line
Industrial Park, Southampton, Pennsylvania in an approximately
70,000 square foot steel and masonry building.  Approximately
55,000 square feet are devoted to manufacturing, and
15,000 square feet to office space.  The original building was
erected in 1969 and additions were made in 1973, 1976, 1985 and
1991.  This property collateralizes the Company's revolving
credit facility.

      The Company considers its machinery and plant to be in
satisfactory operating condition and adequate for the Company's
present level of business.  Increases in the level of operations
beyond that expected in the current fiscal year might require the
Company to obtain additional facilities and equipment.

Item 3. Legal Proceedings

      A lawsuit was commenced against the Company in April 1997 in
the United States District Court for the District of Puerto Rico
by an employee of a customer who claims to have been injured as a
result of an alleged malfunction of a sterilizer manufactured by
the Company.  The plaintiff is seeking $3 million in damages. 
Based on the available information, the Company believes that it
possesses meritorious defenses to such action.  The Company has
up to $10 million of products liability coverage, subject to a
$100,000 deductible.   The Company has notified its insurer of
the lawsuit, and the Company's insurer has engaged counsel to
defend the Company in this matter.

      Certain other claims, suits and complaints arising in the
ordinary course of business have been filed or are pending
against the Company.  In the opinion of management, all such
matters are reserved for or are adequately covered by insurance
or, if not so covered, are without merit or are of such kind, or
involve such amounts as would not have a significant effect on
the financial position of the Company if disposed of unfavorably.

Item 4. Submission of Matters to a Vote of Security Holders

      None.

      Section 16(a) of the Securities Exchange Act of 1934
requires the Company's officers and directors, and persons who
own more than ten percent of a registered class of the Company's
equity securities to file reports of ownership and changes in
ownership with the Securities and Exchange Commission ("SEC") and
the American Stock Exchange.  Officers, directors and greater
than ten percent shareholders are required by SEC regulation to
furnish the Company with copies of all Section 16(a) Forms they
file.  The rules of the SEC regarding the filing of such
statement require that "late filings" of such statements be
disclosed in the Company's proxy statement.
