Aviation
regulators push for more automation so flights can be run by a single pilot
This is despite a wealth of evidence showing the value of
having two in the cockpit

Regulators are pushing the UN's International Civil
Aviation Organization (ICAO) to examine ways of making single pilot operations
the eventual norm in commercial flights.
The area
that I think is the most concerning is a pilot sitting on their own in the dark
and tired at 3am body clock time for four hours with only text messages from
air traffic...
In a working
paper [PDF] filed
with the aviation standards body, the European Union Aviation Safety Agency
(EASA) requested on behalf of member states that the "necessary
enablers" be created "for a safe and globally harmonized introduction
of commercial air transport (CAT) operations of large aeroplanes with optimised
crew/single-pilot operations while ensuring an equivalent or higher level of
safety compared to that achieved in current operations."
There are two obvious drivers for the proposal – cost
cutting and crew shortages. Technology has over decades reduced the need for
more people in the cockpit and the hope seems to be that further improvements
can pare the current two down to one.
"One of the driving factors for the industry to
propose taking advantage of the introduction of these new concepts of
operations is a foreseen reduction in operating costs," the paper says,
though it does note: "Potential additional costs related to higher-level
ground support and two-way communications should also be considered. On the
aircraft manufacturer side, the development and certification of new cockpit
designs and associated systems may require significant investment, although
these will likely produce safety benefits and savings in the medium/long
term."
The requirements for a full flying license are also
incredibly onerous, which creates a bottleneck in the supply for qualified
pilots. For most European airlines, you need 1,500 hours flight time before you
get a full license. Until then, you're on provisional terms and need a fully
qualified pilot operating alongside you.
Nonetheless, single pilot operations (SPO) seems to be
the direction of travel for the aviation industry. Chris Kempis, director of
flight operations at Cathay Pacific, described it as "the
unavoidable challenge" at
the International Air Transport Association (IATA) Safety Conference last
month, but said it is "many, many times more complex" than going from
three crew to two.
EASA's Safety
Risk Assessment Framework for
Extended Minimum Crew Operations (eMCO) and SPO aims to address the following
points:
·
Pilot
workload: Ensure that the workload of the single-pilot during the cruise phase
of the flight is acceptable in normal, abnormal, and non-normal operations.
·
Pilot
error: Ensure that the cockpit design is appropriately tolerant of errors,
noting that when operating as single-pilot, there is no scope for
cross-checking actions by another pilot.
·
Pilot
incapacitation: Detect whether the single-pilot during the cruise phase of the
flight is no longer fit to fly. Ensure that the level of safety remains
acceptable in case of pilot Incapacitation.
·
Fatigue:
Ensure that the level of fatigue remains at least as acceptable as for
conventional two-pilot operations.
·
Sleep
inertia: Ensure resilience of the aircraft and of the operational environment
for the time required for the resting pilot to recover sufficiently from the
effects of sleep inertia that they can either take command of the aircraft and
continue to a safe landing in case of incapacitation of the pilot-flying or be
able to assist the pilot-flying with a complex failure scenario.
·
Breaks
due to physiological needs: Allow the single-pilot to temporarily leave their
station to attend to their physiological needs during an eMCO segment of the
flight while ensuring an acceptable level of safety and security.
"The psychological barriers are probably harder
than the technological barriers," Boeing Southeast Asia president
Alexander Feldman told a Bloomberg business summit in Bangkok last week. "The
technology is there for single pilots, it's really about where the regulators
and the general public feel comfortable."

And there is reason for concern. Just to look at
Boeing, not even two pilots could overcome the 737 MAX airliner's flawed MCAS software, which played a part in the deaths of 346 over two
doomed flights in 2018 and 2019. Obviously, there could be no limit to the
amount of testing and vetting with regard to any further reliance on
automation.
There are also a number of events in recent memory
which demonstrate the value of having two pilots in the cockpit. Germanwings
Flight 9525 crashed in 2015, killing all 150 on board. Co-pilot Andreas Lubitz
had been treated for suicidal tendencies and was declared unfit for work by his
doctor. Lubitz kept this information from his employer and reported for duty.
Once the aircraft, an Airbus A320-211, reached cruising altitude, Lubitz waited
for the captain to leave the cockpit, locked the door, and began a controlled
descent into the side of a mountain.
Following the incident, EASA itself recommended that
there be two authorized personnel in the cockpit at all times. The rule has
since fallen out of favor with regulators.
There is also the "Miracle on the Hudson" of
2009, where the captain and first officer in tandem safely landed a US Airways
Airbus A320 on the Hudson River after striking a flock of geese, causing both
engines to fail. All on board survived.
"Proposed automated solutions do not provide the
same safety and security margin as having a second rested, qualified,
well-trained pilot physically present on the flight deck," says
another ICAO
paper [PDF] on eMCO
dated August 2022.
A commercial pilot who spoke to The Register on the
condition of anonymity said: "I would say it's more of an ambition of the
airlines and aircraft manufacturers. I have certainly had conversations about
it with our managers (who deal with Airbus) in the past.
"The area that I think is the most concerning is
a pilot sitting on their own in the dark and tired at 3am body clock time for
four hours with only text messages from air traffic.
"It's mentally tough going and more likely to
result in the build up of anxiety and stress when something goes wrong. Pilots
are trained to be open and questioning of plans of action e.g. asking the other
pilot what they think is the best direction to turn to avoid the thunderstorms.
"Also the vast majority of problems in cruise on
long-haul flights come from the cabin. I assume the single pilot would have to
give total control to the ground monitoring team while they deal with the cabin
issue. Not sure the data link systems are up to that.
"Having two pilots at the front seems like a
small price to pay to get to where you want to go in one piece." ®
