The Real Deal:
In February 2014, the National Transportation Safety Board (NTSB) released a safety alert recommending simulator training for helicopter operators (bit.ly/ntsb-helisim).
Safety through Helicopter Simulators cited several examples of how simulator training using real-life scenarios could have prevented fatal helicopter events. Simulators provide large and small operators with a variety of training options that are cost-effective, realistic, and can be tailored to specific mission profiles. And simulator training will not put your pilot or aircraft at risk. Building simulation
training into your safety and training program is simply the right thing to do. Still, if you’re new to simulator based training, getting started can be confusing. What should you look for in simulator-based training? Should you build your own program or choose a vendor? What kind of training is best? How does training credit work? Let’s look at what you can do to get the most out of your investment in simulator-based training.
A Long Time Coming
Simulator training has proven itself in other aviation sectors for decades, but it took longer to gain traction in the helicopter world. Demand was not obvious. Helicopter operations had traditionally been conducted literally under the radar of most aircraft and simulator manufacturers, and training remained unstructured. Sikorsky and the larger Bell aircraft had simulation options available, but there was little impetus to bring other options online in a timely fashion. However, as the helicopter industry has matured, so too has the demand for more high-tech training. The number of oeprations are increasing, technology is expanding, and mission profiles are being added. Moreover, accident investigations started to reveal a lack of effective, standardized training for common hazards. It has taken almost a decade for scenario-based simulator training to be made available to the majority of commercial helicopter operators, but today there are a wide range of helicopter simulator options available. Most operators — with a little strategic planning — can take advantage of simulator training to improve their operational safety.
Simulators: The Facts
The most basic question
that pilots and operators ask about simulator based training is this:
can simulator experience substitute for training conducted during
flights?
Actually, simulators
offer more comprehensive, cost-effective training at lower risk
to the aircraft and trainee. When using a simulator,
emergency scenarios can be played out in a way that you could never
do in a real safety alert, “During flight training, it is difficult
to recreate the element of surprise and the realistic,
complex scenarios that pilots may experience during an emergency.
Without simulators, viable lesson components may be limited.” Without
the benefit of simulator training, even high-time pilots may never
have the chance to practice an entire emergency procedure to
completion. Simulator scenarios can be tweaked so that the trainee
doesn’t always know that, for example, an autorotation is coming or that
the warning light will eventually lead to an engine failure. In
addition, simulator training offers pilots increased authenticity and
the chance to safely experience the consequences of their decisions: there’s no need for the instructor to take
over when the flight goes awry. In this way, simulator training
better prepares pilots for real emergencies and unexpected hazards.
Another advantage of
simulator training is that it’s safe for both the pilot and
aircraft.
Indeed, training in
an actual helicopter can stress the aircraft or put it at risk.
Finally, simulator training can often be more efficient. When
practicing approaches, for example, there is no need to reposition
the aircraft before another attempt. If a student needs additional repetition on a procedure, the
reinforcement can occur immediately. Costs for simulator training
will depend on several factors, including the type of training and
the type of simulator. However, when comparing costs for simulator
and aircraft training, consider that training in a helicopter will
take the aircraft (not to mention the instructor) out of revenue-generating operations for
the length of training, and often longer when adding dual controls.
You should also take in account the cost of fuel and wear and tear to
the aircraft.
The Essentials of Simulator Training
When deciding on
simulator training, the most important factor is that the program
suits the needs of your operation. Your simulator training program
should teach the scenarios that fit your operational
profile, including mission, visual flight rules or instrument flight
rules, day or night, and geographical properties, such
as high-altitude or over-water flights. Simulators are most
effective when specific to both aircraft and mission; however, the
mission-specific factor is actually more important than aircraft specific. Developing pilots’ critical thinking skills through exposure to scenario-based
training is viewed as a factor in decreasing accident rates.
When you combine scenario based training in an
aircraft-specific simulator, almost any type of training can be accomplished for initial, recurrent, and human-factor training requirements.
Leasing Simulator Time
Your first decision in
developing your simulator training program may be whether you should
build your own training or use a training vendor. In this case, the
choice is simple. Do you have the staff resources to build
and instruct a training program? If the answer is yes, or even maybe,
then the option to “dry” lease simulator time can be cost-effective,
and the scheduling options for leasing simulator
time can be more flexible as well. Building a training program around the simulator is not as difficult as it sounds. There are resources and sample programs to get you started. To be eligible for FAA credit, a Part 135 operator must get his FAA principal operations inspector (POI) to approve the training program. This can be accomplished fairly quickly if you use a standard course template approved for similar operations. Some operators will share their approved courseware; the simulator provider may also offer generic and sample training programs. Once you have a standard template, it is important to
adapt the simulator scenarios to reflect
actual missions or routine flights
within your organization so pilots
receive training on the conditions
they will face in the field. Some operators
have used information from incident
and accident reports to create
training scenarios. Once the scenarios
are in place, they can be adapted for
new situations and pilot
competency.
Turnkey Solutions
If you don’t have the
in-house staff to develop your own simulator training, you can choose
from a number of providers. One advantage of this approach is that
the cost is usually fixed: initial and recurrent courses have set
rates and schedules. The company will provide all of the training
materials and instructors, as well as the simulation. In some
cases, aircraft are available to supplement the
simulation. If you have recently
purchased an aircraft, you should
know that some manufacturers have
added simulation to their training
offerings. In some cases, additional
training options are available that
include mission specific recurrent
training or special equipment such as
night-vision goggles.
Match Training Scenario to the Mission
When considering
simulator training, many first look for a simulator based on a
particular aircraft. However, a causal factor in most accidents is
not the pilot’s unfamiliarity with the aircraft. Rather, most
accidents involve poor pilot decision making because of distractions
and human factor elements. For example, a pilot’s decision to press
on in inadvertent instrument meteorological conditions (IIMC) is more
about that pilot’s reaction to unfolding events than his or her
expertise in flying a particular aircraft. It’s great if you can
match your simulator training to the types of aircraft in your
operation. However, in most cases, matching the training scenarios to
the typical missions flown by your pilots is even more important.
Whether you are building your own training program or
purchasing an off-the-shelf product, put some time into thinking what
you want your pilots to practice. Scenario based training should
include the typical scenarios faced by your pilots, with aircraft
malfunctions and environmental distractions added in.
If all of your flights
are offshore to oil rigs, then your training scenarios should include
these types of flights and the accompanying “standard” emergencies,
such as ditching. If a typical mission for your operation is to
navigate through mountainous terrain to small, unlit landing zones,
your training scenario should incorporate these features, providing
pilots with the challenge of maintaining situational awareness while
making good decisions. The same is true for practice in cold weather
operations, high and hot situations, and IIMC — the latter being a
common event in almost all geographical locations and a factor in the
highest percentage of fatalities in helicopter accidents. Almost any
situation, distraction, or environmental obstacle can be depicted in
a simulator. The goal in these cases is to establish a pattern
of critical thinking skills in unexpected or unfamiliar circumstances
— building confidence and professionalism, which ultimately leads to
safer decisions.
Technical Lowdown of Training Credits
There are two categories
of devices recognized by the FAA to provide flight simulation
training. A flight training device
(FTD) is a non-motion trainer that replicates a
specific aircraft, including instruments, equipment, panels, and
controls, in an open or closed flight deck. A full flight simulator (FFS) is the
most advanced type of flight simulation available to pilots
and training institutions. An FFS has a motion base and includes a
full replica of a specific make, model, and series of aircraft
cockpit. All aerodynamics, flight controls, and systems must perform
as the actual aircraft would
in flight. More information
about the different flight simulation training devices approved by
the FAA is listed below.
FAA-Recognized Flight Simulation Training
Devices
Flight Training Devices (FTD)
FTD Level 4 • Helicopter-specific with at least one operating system
FTD Level 5 • Helicopter-specific with at least one operating system
• Primary and secondary controls must be physical controls
FTD Level 6 • Enclosed helicopter-specific flight deck and aerodynamic program
with all applicable helicopter systems operational
• All controls, switches, and knobs must physically replicate
aircraft control operation
FTD Level 7 • Enclosed helicopter-specific flight deck and aerodynamic program
with all applicable helicopter systems operational
• All controls, switches, and knobs must physically replicate
aircraft control operation
• Visual system must provide cross-deck viewing from both pilot
seats
• Vibration cues are available to enhance realism of training
experience
Full-Flight Simulators (FFS)
FFS Level B • Requires at least a three-axis motion platform
• Visual system responds to pilot input of controls within 300
milliseconds
FFS Level C • Provides motion platform with all six degrees of freedom
• Simulator controls must replicate feel of aircraft
• Visual system responds to pilot input of controls within 150
milliseconds
• Visual system has 180-degree field of vision; can replicate
visual illusions for landing, dusk, daylight, and special weather situations
FFS Level D • Provides motion platform with all six degrees of freedom
• Simulator controls must replicate feel of aircraft
• Visual system responds to pilot input of controls within 150
milliseconds
• Visual system has 180-degree field of vision; can replicate
visual illusions for landing, dusk, daylight, and special weather situations
• Motion and aural effects are available to enhance the realism of
the training experience
In each case, as the
simulators go up in complexity, they provide a more realistic
training environment in terms of the flight systems, visual display,
motion simulator, and cockpit
environment. The highest
level, FFS Level D, provides a motion platform capable of moving in
all six degrees, a visual system with a view of 180 degrees, and a
number of special motion, visual, and aural effects to provide a realistic
cockpit environment. The FAA awards training credit to pilots
who complete an approved training curriculum according to the level
of training device used. The amount of training credit is subject
to the interpretation of the POI and may reflect differences based on
type of operation or unusual environmental challenges.
Many operators have
questions in regard to the training credit allocated in different
devices. The final decision as to the amount of training credit for a
Part 135 operator is entirely the decision of their POI. In general, however,
the more complex simulators receive the higher amounts of
training credits. For example, almost everyone gets 100 percent
training credit for work done in a Level D FFS, which is used by Part
121 airline operations and many
Part 135 corporate
fixed-wing operations. This level of simulator is also the most
expensive. Credit obtained for training in a Level B or C FFS depends
on the equipment capability and the
decision of the POI.
Another factor in
choosing your simulator is cost. In general, the more complex
simulators are more expensive. This is why it’s important to review
your budget and think about what you want to get out of the simulator
training. For example, there is a significant difference in
the operating costs of a Level D FFS and a Level 7 FTD. It can be
very cost effective for an operator of single engine aircraft (Airbus
Helicopters AS350, Bell 206, and Bell 407) to use
the Level 7 FTD.
Training credit for a Level 7 has been equal or better than a Level B
full-motion simulator and costs a lot less to use. The latest
technical advances in simulator visual systems provide a very
realistic training environment. There are a number of Level 7
FTDs for single-engine helicopter training, and training credit
ranges between 80 and 95 percent, depending on the operator and the
POI.
A Level 6 FTD gets
a slightly lower training credit as it usually does not have a seat shaker
or vibration in the simulation. Anything below a Level 6 will
definitely have training value; however, FAA training credit varies
significantly. Some operators have expressed concerns about
receiving anything less than 100 percent of the training credit.
However, if you consider that most operations require some sort of
local area orientation flights, the difference can easily be made up
in the aircraft at minimal cost.
Plan Ahead for Maximum Payoff
There is no
one-size-fits-all answer to simulator training. But there is
an answer that will fit most operations and budgets — and, as the
NTSB has stated, “Consistent, standardized simulator training will
help prepare pilots for the unexpected and will decrease the risk of
an accident.” To get the most out of your investment in simulator
training, develop specific goals for the training that match your
operational challenges. Then research the most cost-effective means
to meet those goals. There are many resources to help you get started
in building an effective simulator training program — and eventually
a safer flight operation.
