A
PCATD History & Guide for Practical Applications of PCATDs
History
and Development
Letters
exist dating back to 1969 requesting approval for the use of
PCATDs in flight training. PCATDs have had to overcome evaluation
based on their physical fidelity rather than whether or not
they were effective teaching devices. However, with the advent
of realistic flight controls hardware, they have finally been
able to overcome this limitation.
PCATD
development was guided by three main premises:
-
Provide
a minimal level of positive transfer of training from the
PCATD to the airplane;
-
Avoid "negative transfer" and
-
Take advantage of the computer, which presents unique opportunities
for enhancing the learning environment for aviation training.
Positive
Transfer of Learning is Not an All-or-Nothing Phenomenon
Every
complex skill consists of a number of component skills. These
component skills can consist of a motor movement, perception,
retrieval of information from memory, or processing information.
Mastering any complex skill involves three stages:
-
The
understanding of task objectives, task parameters, and any
procedure involved, through
-
The
establishment of correct patterns of behavior, and finally
-
The point at which the task becomes largely automatic.
In
most flight training environments, all three stages of learning
are being accomplished using the aircraft. The PCATD is designed
to support the learning of tasks through the first two stages
of skill acquisition, where sufficient positive transfer of
training for that task can be expected. This is the most efficient
and cost-effective method of learning in an aviation curriculum.
In
1992, 79 students enrolled in an instrument flight training
course and were trained using PCATDs in conjunction with the
airplane. Instructors used a form, based on criteria specified
in the Instrument Practical Test Standards (PTS), to evaluate
student performance on 6 maneuvers and 2 categories of general
flight skills. Records were also maintained on the number of
trials, hours to proficiency, and the number of trials per task.
The
study concluded that the students trained with the PCATDs required:
- Significantly
fewer trials, hours, and trials per task, to teach the overall
PTS, and
- Significantly
fewer trials to reach proficiency in the following maneuvers:
precision approach, nonprecision approach, timed turn to
magnetic compass heading, and partial panel.
Based
on very conservative estimates, at least $400 less was spent
to train each student on the PCATDs. With respect to cost effectiveness,
the PCATDs and associated hardware amounted to approximately
8% of the cost of currently approved ground training devices.
Furthermore, students were trained for approximately $18.50
less per hour on PCATDs than on simulators. The cost of training
was lowered, and the students received more effective trainingwithout
needing to lower instructors wages.
What Does the FAA Expect and Allow for PCATDs?
The
FAA looks for PCATDs to become a part of comprehensive instrument
training curriculums, to supplement accepted and proven methods
already in use. PCATDs are not designed to replace simulators,
FTDs, or aircraft, but to become an integral part of an effective
and multi-faceted overall training program.
Usage
Allowances
14
CFR §141.55 allows PCATDs to be used in a curriculum as
courseware (similar to videos, manuals, etc.). The FAA encourages
the use of PCATDs to supplement traditional ground training
techniques.
AC
61-126 defines PCATDs and allows 10 hours of loggable time towards
an initial instrument rating.
To
log time on a PCATD:
- The
system must be used in an integrated ground and flight training
curriculum;
- Any
training time must be endorsed by an instructor qualified
to provide the level of training given;
- The
flight instruction must consist of the procedural tasks
listed in AC 61-126, Appendix A, and be presented with study
materials that support these tasks; and
- The
system must be approved by the FAA in accordance with AC
61-126.
Part
61
To be
used in a Part 61 training program, the curriculum must be
in general compliance with the scope and content of a curriculum
as it would be approved under Part 141.
Students
may log 10 of the 20 hours granted for flight simulators and
FTDs.
Part
141
To
be used in a Part 141 training program, the overall curriculum
that includes the PCATD and its usage must be approved under
Part 141.
Students
may log 10 of the 15 hours granted for flight simulators and
FTDs.
Ground
Training
Often
in aviation, too much emphasis is placed on the issue of logging
hours, and the availability of these hours has been a
driving force in PCATD acceptance. But instructors worldwide
used IFR simulation software to explain difficult concepts,
develop scan, and teach procedures or tasks in a manner impossible
in the cockpit environment, long before AC 61-126, official
recognition, or university studies of the PCATD.
The
Benefits of Using PCATDs
The
value of PC simulation devices is in their ability to support
training in aircraft systems knowledge and/or the procedural
aspects of flight operations.
The
average number of hours spent in completion of training for
a private pilot certificate is between 60 and 65 hours (regulations
require 35-40 hours). The average number of hours spent in completion
of training for an instrument rating is between 60-70 hours
(regulations require 35-40 hours). Any type of training aid
that can reduce this average time will be beneficial to the
flight student. The ability of a PCATD to enable students to
obtain their pilot certificates in less than this average
amount of time is a great marketing tool for schools and instructors.
-
PCATDs
enhance safety because students gain minimum proficiency
before attempting maneuvers or procedures in the aircraft.
An understanding of the concepts or tasks at hand can only
help to reduce student pressure and workload in actual flight
training.
-
PCATDs
improve pilot skills by allowing the student to practice
in realistic settings, and repeat a given maneuver until
it is performed correctly, significantly reducing costs
associated with aircraft training. While these same statements
apply to training in an aircraft, the cost associated with
their use, and the demands of the ATC environment, make
the repetition required for solid learning difficult to
achieve.
-
Without
the noise and confusion generated in the real cockpit, students
concentrate much better which leads to quicker results.

Training
time could be reduced, which should result in a reduction of
costs for both students and flight schools. By reducing costs,
the flight school should be able to attract additional students,
thereby increasing the student load and potential business.
Also, the ability of students to gain self-guided practice at
some tasks and maneuvers should improve skill maintenance and
pilot proficiency.
PCATDs
are a superb teaching tool. Using them takes the teaching process
out of a hostile environment (the training airplane) and puts
it on the computer. Learn on the computer - practice and refine
in the airplane.
Implementing
PCATDs into a Flight Training Curriculum
Ideally,
all aspects of the training curriculum could be taught to some
criterion performance level on the ground before demonstrating
competence in the airplane. This positive transfer of learning
would greatly reduce the flight training the average pilot needs
to complete his/her instrument or private rating curriculum.
Implementing
PCATDs into a flight curriculum accounts for individual differences
between trainees by providing a way for slower-learning students
to increase their training time on the ground without greatly
increasing costs for them.
PCATDs
provide the incentive to follow a more integrated program of
ground and flight training. Current programs employ two distinct
approaches. The ground training involves teaching flight relevant
knowledge (procedures, weather, flight planning, airport lighting,
etc.). The flight training allows the practice of flight skills
(takeoffs, landings, turns, etc.). An integrated program involving
computer-assisted instructional methods provides feedback, repetition
learning, and review of those specific areas where the student
needs help.
How
many instructors have had students suffer from information overload?
Because of the dynamic and complex systems associated with a
typical flight training program, most students are forced to
digest many lessons within a single flight. PCATDs present the
unique opportunity to fine-tune individual skills before using
them in conjunction with other tasks. The foundation for operating
in an IFR environment is attitude instrument flying, yet the
airplane prevents teaching these crucial skills without interruptions.
Sloppy skills are almost guaranteed when a student progresses
to new learning without mastering previous lesson - the building
block technique is essential when working with instrument students.

Additional
Considerations: Students may purchase desktop flight simulator
software packages (although these are not qualified as a PCATD),
and practice individual skills or acquaint themselves with new
approaches on their own.
An
instructor, upon discovering weaknesses in key areas of flight
technique or procedural understanding, can ask the student to
practice at home within well-defined guidelines. Though not
performed on an approved device, this practice can only enhance
the mastery of complex skills discussed earlier. While the procedures
of instrument flight demand strict supervision to be learned
effectively, the student at home can practice scan, learn to
think ahead of the airplane and familiarize themselves
with practice airspace without any negative transfer
effects.
Perhaps
most importantly, this approach will add a whole new excitement
to homework, and prevent the Id rather be spoon-fed
than do homework attitude of many students.
Conclusion
There
is no final authority on how these devices may be integrated
into todays flight training. However, it is helpful to
refer to The Pilots Manual Instrument Rating Syllabus
for a recommended ground/flight training curriculum that implements
PCATDs.
We
urge the users of PCATD technology to communicate with us their
own experiences and techniques as PCATD usage continues to grow,
and to help further define this exciting new field. It is incumbent
upon the practitioners in the field to help the FAA keep up
with rapidly-changing technological enhancements and their applications.
As we work closely with the FAA to help refine PCATD usage,
we ask for the input and feedback, positive or negative, from
users of this technology.
Questions
Some
of the Frequently-Asked Questions (FAQs) we have received during
the Qualification Process of the On Top PCATD are reprinted
here for your benefit.
Are
PCATDs approved for currency requirements or flight training
after the instrument rating?
At
this time, approval is only granted for use during primary instrument
flight training. FAA-sponsored studies are currently underway
to evaluate PCATD applicability to currency requirements, instrument
proficiency checks, VFR training environments, and other areas
of flight training.
Do
local FSDOs need to approve every installed PCATD?
No.
The FSDO approves the overall program of a Part 141 school or
organization that incorporates a PCATD, as part of their overall
141 approval process. But individual approval is not required,
and Part 61 programs require no additional approval to use an
already-approved PCATD. Part 61 programs must, however, use
the PCATD in a curriculum that is in overall compliance in scope
and content with a Part 141 program.
AFS
800, the General Aviation and Commercial Division, signs and
delivers an acceptance letter with each PCATD model approved
by their office. A copy of this letter accompanies every On
Top PCATD that is shipped to a customer (see Section 1 of this
guide), and can be supplied to the local FSDO during the 141
approval process.
Are
there any limitations to using a PCATD in ground training?
No.
PCATDs easily fall into the same category as videos, books,
manuals, chalkboards, whiteboards and audio tapes. Each of these
represents a medium for explaining the details of instrument
flight in an understandable way.
As
a Part 61 instructor, what equipment do I need to train my students
on a PCATD?
You
need an approved PCATD, with a current navigational database
for the area in which actual training takes place; a personal
computer and monitor that meets the hardware requirements of
the PCATD, copies of all letters of acceptance of the device;
an integrated ground and flight training syllabus that incorporates
PCATD usage; instructional materials designed to teach the tasks
being taught on the PCATD; and you need to teach a curriculum
that is in general compliance with the scope and content
of a Part 141 curriculum.
