The value of a Hobby
Life is generally busy. Between home and work, and the all the maintenance that goes into keeping life running, there isn’t much time for anything else. Until you make some.
Over the past 6-8 weeks most of us have been under lockdown or ‘shelter in place’. During this time, many have asked me what I do or how I spend my time. The fact is that I really have had no time to ‘spend’. It has been busier than ever and as always, when I have any spare time, I just route towards doing things that matter to me.
On the other hand, even when life is routine. I ensure I make it a point to dedicate my time to those things that define me, make me who I am, grow as an individual.
There are 1440 minutes in a day, times 7 days, times 52 weeks. It is hardly possible that we can’t find the time to do the things we want to do. The question is never about time. There is always enough time for everything. Talk to people who speak about the quantum realm and they will be first to point out that time will warp to allow one to do the things they are passionate about.
For many, perhaps I should say most, the hardest thing is to know what they would like to spend their time on. Before we can be passionate about anything, one has to know oneself.
What do I like to do? What would I like to spend my time on? what do I want to create? What impact do i want to leave behind? What do i want to be known for when i am done? What problems do i want to solve? Who can i help? Who can i serve?
Most people go about life living through the drudgery of tasks and when they look at others doing things that matter to them, it appears like those people are blessed. The fact is that those people are neither anymore blessed than us, nor are they gifted with any more skills that we have. The fact is that those individuals have identified one or more things they are truly passionate about and they pursue it relentlessly.
In simple terms, some of these ‘things’ are known as hobbies. they are different from interests. They are not pastimes. Hobbies involve deep engagement, a form of ‘doing’.
I consider myself very blessed to have had a passion for aviation. This passion has led to various related hobbies and I have more than one. Model aircraft building, drone flying, simulator construction, real world flight, aviation photography and videography, composing guitar solos to mirror the sentiments that aviation produces. These keep me grounded and level-headed. Working on my hobbies brings in a focus, keeps the mind engaged, provides a sense of calm, generates immense gratification, and increases creativity exponentially.
One of the questions that i get asked when someone sees my work is how did i begin. I don’t think there is a single day when a hobby becomes a part of one’s life. Most of my hobbies came in naturally. They grow on me. Aviation has been a passion since my childhood. Music has been with me since my high school days. I was building transistor radios when i was 12. So most of my hobbies have stayed with me since i was little. Indeed with time, the size and scale of my hobbies have grown much. Where I would build a small scale model aircraft, I am now inspired the next larger one. Where i used to have one certificate to fly, I am now inspired to pursue the next block of learning and get the next certificate. Where a couple of decades ago, I was only interested in finding out how to eliminate the keyboard and replace real switches and knobs into a flight simulator, I started on building a scale size flight simulator. It turned into a 20+ year project and to this day gives me immense satisfaction. I call it it my life’s work.
Yes, hobbies can lead to life size work. There is always something to do. Replace the engine on a model aircraft, try a new propeller to test for efficiency, build a foam plane with electric propulsion. Fly to a new non-towered airfield in the real-world. Plan a project to fly to the sand dunes at Kitty Hawk where the first powered flight occurred. On the simulator side, update navigation data, upgrade the software, add a new aircraft, or fine tune performance. If all this is finished, sit by a small airfield and do some plane spotting, or curate some aviation pictures. When this done, come back to composing a new solo in A minor to mirror the feelings of being in the air. There is no end of the avenues that hobbies open up.
The hardest for many is to identify what they are really interested in. The best way to get past this point is to try a few things. Its easy to gravitate to one or more things if we try them, It’s also important to separate out pass-times from hobbies. Hobbies are most likely things to do. Pass-times are meant to pass one’s time. Rest assured that having a hobby will leave very little time to pass.
A hobby can be in any field or realm. Tending a garden, collecting stamps, curating pictures of building architecture, sewing, knitting. cooking, painting, woodcraft, restoring a vintage car or plane, curating artifacts for a museum.., there is no end to the various things that one can do with time.
At few points in our past would having a hobby be as immensely valuable as it has been over the past two to three months with the COVID-19 situation.
In the spirit of not leaving the sight of a goal without taking a step towards it, let’s begin!
Let your creativity blossom.

Air Traffic Management – what the does future hold?
It is clear that air traffic management (ATM) across the globe is changing and changing rapidly. For the past several decades ATM has remained fairly constant and while changes have occurred they have been evolutionary. However, changes that are on the anvil are revolutionary and transformational.
Regardless of whether its NextGen in the US, or SESAR in Europe or CARATS in Japan, air traffic management is about to change permanently. Each of these programs has multiple tracks and while each of these programs gives these tracks different labels, there are many similarities in their goals. Efficient flight routing, fuels savings, noise abatement, balancing separation and safety, minimizing weather impact, shifting the dependence on voice communications are examples of the goals of these initiatives.
Its evident that with such a vast slew of changes, there will be impacts from a human factors perspective. A wide variety of tests are in progress to determine the totality of these impacts. The role of the human within the operation will change. Whether its providing clearances or issuing instructions through voice communications, the role of the individual is up for change. Air traffic is increasing rapidly. Passenger volumes are on the rise. ATM is in dire need of change. The dependence on the individual is here to stay for a long time, however, the system can be designed to help rather than burden the individual. One observation that can be drawn from the videos is that ATM may be at risk of experiencing the same type of issues that aircrafts went through when large scale transformations were introduced. One of those examples is flight deck automation. While the autopilot and FMS were valuable additions to the flight deck, they brought along with them several new risks. Some of those risks continue to materialize several years after those innovations were introduced.
It is not difficult to envision these types of risks when ADS-B, ERAM, Digital Voice, Performance-based Navigation or any of the other tracks in NextGen bring major changes to ATM. All of these change programs will bring relief to roles within ATM while also bringing on new challenges.

Aviation Human Factors and Prospective Memory
Prospective memory is an emerging area of research within the field of Cognitive Psychology and Human Factors. Remembering to perform intended actions can be critical, especially in safety-related occupations like Air Traffic Control.
Failures in prospective memory (PM) are the reason why we fail to perform intended or required actions. There is increasing interest in the topic of prospective memory and the reasons for failures of such memory. While this subject is still under intense debate, according to one school of thought, prospective memory recall is driven by the process of monitoring. Another view is that it occurs as part of spontaneous retrieval. In either case, the intention for the planned task is retrieved which then allows for action. Distractions are one source of why action is forgotten.
Interruptions of any kind can be a cause (Shorrock, 2005; Sternberg & Sternberg, 2016). A telephone call or request for information can be sufficient cause to not return back to the ongoing task. The variety of peripheral tasks that controllers need to perform often conflict with the primary task of maintaining separation. Such tasks could include scanning displays, accepting aircraft, gathering and relaying weather advisories and responding to pilot requests.
Prospective memory recall is predicated on cues. A cue or trigger is necessary for prospective memory to work. As described earlier, to recall the intent, the human mind constantly polls for such items. When polling is not invested in, such as when we are preoccupied with other task(s), then the intent is not recalled and action is termed as ‘forgotten’. Under another school of thought, spontaneous retrieval occurs on account of a system within our brain that causes automatic retrieval of items at the appropriate times. Once again, when tasks preoccupy, spontaneity drops and we tend to forget the intent. Proximity, recency and task regularity could all affect prospective memory (Vortac, Edwards & Manning, 1995).
In the context of ATC, prospective memory failures can prove to be catastrophic. The incident at San Francisco of a controller positioning an aircraft on the runway for takeoff, forgetting about it, and further clearing an aircraft to land on the same runway is a case in point (Loft, 2014). They can affect controller actions such as separation, scope monitoring or performing other tasks such as flight strip updates, aircraft transfer, peer collaboration and shift transitions. Inaccurate recall of information on a strip, failing to observe conflicts and failure to annotate strips correctly are all examples of PM failures. Controllers may intend correctly but then fail to follow through on that thinking because they simply “forgot to do so”. In the realm of ATC, cues are either based on time or based on events (Loft, 2014; McDaniel & Einstein, 2007). However, monitoring takes a cost in the form of “brain cycles” and therefore impacts performance. Such impacts could come in the form of slowing down a certain action in order to devote time to monitoring.
External cues are an effective way to mitigate the risks of prospective memory failure (Vortac & Edwards, 1995). Memory aids are useful and can be any tool, prop or other aid that could serve as a reminder (FAA Video, 2015). They need to be incorporated into the routine though and not be ad-hoc. Mnemonics and placards are one way to avoid prospective memory errors (Loft, 2014; Stein, 1991). Using free text to jot down notes is another option. Memory aids must be effective. A good example from the video is that of holding a strip in hand as a reminder when there is a vehicle inspecting the runway. There is a growing interest in having the system alert and warn if an action is overdue. The sophistication available today makes it possible to code rules into the system and have it warn the controller. However, this may lead to the same type of over dependence on automation and sense of complacency that we find occur in pilots.

Simulator Benefits
There is little doubt that simulators have redefined the realm of initial and recurrent training in both Military and Commercial aviation. Cost benefits have been a primary consideration. Lowering the risk of training has been the other major benefit. Achieving balance between simulator and real-aircraft training time has been a subject of much debate and research. Leaning too much to either format has impact. On one side, cost impacts could be significant. On the other, the trainee has little feel for what it is like to be performing this tasks in a real aircraft.
There is also truth to the fact that some areas of training are better handled in a sim while others absolutely need an aircraft. In my opinion, simulators have evolved to a point where they are close to ‘as real as it gets’. Transfer of training has proven to be effective. Aircrafts have become more technically advanced and a lot of training is focused on procedure and automation – an area where sims lend themselves to really well.
Replication of real-world weather, comms, terrain, flight dynamics have become possible. There isn’t a lot of loss in ambient factors in a simulator today.
In fact the term ‘supplement’ almost implies that sims are secondary. That has changed with time. In many areas, simulators end up being primary channels for training while aircraft-based training come in at an equal percentage or less.
Again, the one major risk of doing too much time in a sim is that it may lead to a situation where the trainee has little or no feel for what the real world circumstances will be like. This too, then comes down to how well real world factors are modeled into a simulation ecosystem – aka fidelity.
Aviation Human Factors: Communication to Action
Words spoken or written, absolutely have a deep impact on an audience. The “It’s a Beautiful Day, and I Can’t See It” video is a testament to this reality of life. Language is a powerful tool, and even unspoken words can elicit an emotional response from others.
All action follows perception. In the video, the same message rewritten a different way had a totally different response. The fact that different words caused different response indicates that beyond triggering action, the human brain develops some form of visualization when presented with words. Such visualization triggers emotions. Emotions supplement the action. While the basic action of giving to the blind man remained the same, the quantum of giving was driven by the emotion that was generated by the newly stated signboard.
The first step in human information processing is perception. The process of receipt allows the brain to perform other actions thereafter. So if the perception is formed wrong, all other actions thereafter will also be wrong. In the context of ATC human factors, this is critical to understand. It is for this reason that pilots and controllers speak standard phraseology. Certain terms are exclusively maintained within such standard phraseology to drive certain perceptions followed thereafter by a specific set of actions. For example, an ‘emergency’ call is meant to drive certain actions.
Despite this, mis-perception (and hence incorrect, inaccurate follow through) can be caused due to many reasons. One such reason can be premeditated expectations on the part of the recipient. There are times when a listener is expecting a certain input and regardless of what the speaker says, the listener tends to “hear what she/he expected to hear”. For example, in a recent Flying magazine article, a pilot continued his approach despite the controller asking him to go-around. This is partly because the pilot had a deep set intention to complete his approach and land. In another such article, the pilot made a left 360 despite the controller asking him explicitly to make a right turn. Comfort with a left turn or a premeditated thought, or prior experience at that airport caused him to make a left turn this time. Other factors may play a role. For example, a pilot gets a clearance. It contains an intersection that’s not on the SID. A sense of intimidation can cause a pilot not to ask for clarification. This can lead to issues once in flight. In the case of Avianca 52, the simple use of the ‘emergency’ word may have saved the situation. That term sets a perception. The term “caution” in ATC is meant to drive additional care on the part of the pilot.
So as can be seen the use of (or the lack of use of) certain phrases is very important in the ATC context. On the other hand, the use of non-standard language can be equally damaging. Using non-standard terms dilutes the purpose for which they are meant for. Crisp, succinct use of language is very important in certain operational contexts. Often in un-towered airports, pilots use the CTAF frequency for general talk. One in a while that may be okay but such use dilutes the use of that frequency for more important safety calls.
Communication, perception and action are tightly connected. Words affect perception and perception affects action.
