Although current
standards for airline transport pilots are exemplary, proposed
changes to the ways in which pilots have been trained will
create unwanted reductions of the high standards many have
worked so hard to establish. Technology to fly completely
automatically has existed for over forty years and by
integrating this with existing single pilot certification
standards in business aircraft, it provides a safer, better
option for all: ALB.
The airline industry has an incredible
safety record, particularly given the circumstances of aviation;
factors like operating in sometimes severe weather, older
aircraft and human factors. The tremendously low accident and
incident rate for commercial aviation has lead to a change in
one of BAT’s ventures called ALB technology exploring completely
fully automated flight systems.
One of the main reasons for BATs ALB
technology was the proposed introduction of relaxed training
standards for second officers via a policy called the multi-crew
licence endorsement to address pilot shortages. This crew member
often seen as a system programmer given the flight is conducted
under auto-pilot through 97% of a flight. While certain pilots
would manage well at the standard proposed, average pilots -
especially those uninterested in flying and aeroplanes - would
only deliver a percentage of the current standard of flight
performance, particularly when necessary in emergency
conditions, when a pilots experience is tantamount.
At the same time, airlines are in business to make money,
enhancing systems onboard aircraft to reduce costs can save millions of dollars per aircraft per year,
from aspects like recurrent training of crews (several each jet)
and insurances that can be passed on to consumers. So to make
more money, reducing pilots an airline needs is an advantage,
especially when there are often times of pilot shortages,
artificially inflating salaries. The material is thus at
present dissected to obtain the best balance of cost savings as
well as save the incredible status quo.
The
best balance is considered to be the introduction of enhanced
single pilot operations. Currently, the fastest civil aircraft
in the world can be operated by a single pilot – business jet
types able to cruise at transonic speeds. Given the skills
required to operate a business jet and small airliners are very
similar, having a similar flight envelop except weights, these
systems could be used in increasingly larger types up to certain
sizes. ALB single pilots may be as controversial as ETOPS, yet
the benefits to both airlines and consumers are very real. Cost
savings on smaller jets under 100 seats for example means
commuter airlines will be able to offer much cheaper services.
Some of these savings can be passed onto passengers permitting
more people to utilise and experience the convenience of flying,
perhaps leading to larger, non-ALB aircraft being used.
This
initial research has found certain guidelines for future
enhancement, both in the initial and developed contexts;
Initial expected consideration guidelines

Mitigating factors:
-
Good weather only: pilot
workload is significantly higher in bad weather
-
Day flights only: pilot disorientation
and other human factors such as circadian rhythms are issues at
night
-

would phase in should the pilot become incapacitated

Panic button technology
A
Panic button system has been conceived as a means to reduce
airliner hijackings. Pressing this button instructs the
aircrafts auto-pilot to proceed to the destination or return to
the original airport without crew override. The system also lets
air traffic control know that an emergency exists via a
transponder code squawk code so security teams can be on the
ground to deal with the problem.
The
system works with a simple push of a button, after which the
flight crew and any other person on board the plane cannot
change the destination of the airliner. It is a safe way of
deterring hijackings and is cheap and easy to install on
airliners with existing ability to land on automatic pilot.
Weight can be saved as heavy cockpit security doors can be
replaced with original types, the panic button system a few
grams of computer chip and wiring.

Panic
button technology introduction estimate
Development 3-6 years
Entry
5-8 years (all aircraft above a certain category/class/size/age)
Mandatory on new airliners: 10-15 years
A
certain class of airport and airspace only: debate would centre
upon uncontrolled or fully controlled: there is usually less
workload at smaller airports. The exception is when the weather
is bad, when workload escalates due to fewer navigation beacons
and support systems. There is also less technology at smaller
airports to prevent mid-air collisions with a single pilot
having more to look out for, coupled with a higher workload
could mean distractions leading to accidents.
At
larger airports the only increase in workload is with
communications; there is usually complete radar guidance for
complete safe navigation of the aircraft down to very low levels
of visibility, and radar separation preventing collisions. It is
thereby more probable that single pilot approvals could become
standard at large airports first.
-
Maximum flight distance 300nm: lessens the time of the flight an
also makes the flight more manageable in terms of navigation and
familiarity. This also keeps the crew alert.
-
Maximum time for each flight one hour or less: prevents any but
immediate incapacitation preventing a pilot’s ability to fly the
plane. This limit can potentially move up to three hours with
development.
-
Experienced pilots only with minimum time on type, recency and
total times.
- Pilot to be able to contact or even live feed to other pilots

Data base monitoring:
If an
airline desires, these airliners can feed back to monitoring
staff, allowing 2 pilots to “fly” ten or more aircraft, making
decisions in all aspects in a controlled, supervised manner much
in the manner of RPV's.
•
In an emergency
this crew could take over.
•
In minor
incidents such as light mechanical fault or marginal weather,
go/no-go decisions can be made/overridden as or if desired.
-
Minimum flight distance to be over 50nm; prevents workload
factors being too high for the pilot, having to cope with the
two most stressful areas of the flight within a short time
period. This may be open with restrictions on the number of
times in a day a pilot can do this, to prevent fatigue and other
human factors affecting flight performance.
-
Passenger numbers; initially under 50 people, moving within two
years to 75 passengers, then up to 100 passenger types within
another two years, potentially up to a maximum of up to 175
passengers. Optionally with full integration automation could be
extended to full Pilotless standard.
All technology requires a period of
introduction to allow peoples thinking or finances or both to
catch up with the concept and how it works, ALB
commercial airliners particularly so. ALB technology will become available to
airlines, and if the airlines buy or not will be the deciding
value whether or not the concept becomes mainstream. Airlines
will always have the option of crewed airliners at the purchase
stage, some may
utilise a fleet of part ALB and
part crewed, all crewed, or all ALB – it is up to the airline.

ALB
phase in periods
Initial stage: ALBSPM + single pilot plus monitor pilot
Second stage: ALBSP + single pilot
Third
stage: ALBM + monitor pilot
Fourth stage: ALB
With ALB moving into single pilot category,
a monitor pilot would be carried during the first year or more
of operation to ensure the system operates smoothly; until the
aircraft systems and training standards are considered capable
enough to avoid this protocol. Any faults will result in an
Airworthiness Directive being issued as per a typical problem.
Full Phase
Pilotless airliners
As is, current standards of safety are far
beyond the merit of considering the introduction of full
Pilotless systems. In fact if anything the difference between
automated systems and piloted has swung in favour of the piloted
crew over the last twenty years.
Full ALB systems will eventually have
financial benefits to airlines and passengers. Not requiring a
crew can save up to half a million dollars per year in wages and
training costs, multiply this per the amount of pilots an
airline must employ to meet requirements which includes any sick
leave and it soon trims profit, an amount passed onto consumers.
Added economic benefits come from not needing to provide hotel
accommodation, weight of the crew member plus avionics savings,
hiring and associated office costs and so on.
The reasons why we don’t fly using computers
may be obvious to most computer users. Even with multiple
redundancy factors there have been significant incidents where
crews have overrode a faulty system.
The complexity required
for the precision of flight is high, having to update
information from navigation system, with various weather, weight
and balance, temperature and other changes to compensate for. A
sight abnormality can introduce an error which escalates
rapidly, as seen in Chaos theory. Diversions from desired and
actual position take milliseconds, introducing errors: exactly
like those experienced by sailors before the chronographs
invention: airliner speeds reintroduces the issue. Optical
clocks may reduce the problem in the future.
When computers do work properly - or – as
intended, the systems provide levels of precision only the best
of pilots maintain. Yet however good a computer system is,
sooner rather than later a human must be involved: whether
programming it for basic navigation, air traffic control,
maintenance or others in a long chain of staff getting an
airliner into the air, all hinging on flight safety adding an
element of risk which a computer alone can not deal with. We
have a commercial aviation system to be grateful for with thanks
to the special people who work in aviation.
