Fear of flying
This article needs attention from an expert in Neuroscience, Psychology or Pharmacology.(April 2012)
Fear of flying is a fear of being on an airplane (aeroplane), or other flying vehicle, such as a helicopter, while in flight. It is also referred to as flying phobia, flight phobia, aviophobia or aerophobia (although the last also means a fear of drafts or of fresh air).
Fear of flying may be a distinct phobia in itself, or it may be an indirect combination of one or more other disorders, such as claustrophobia (a phobia of being restricted, confined, or unable to escape) or acrophobia (anxiety or dread of being at a great height). It may have other causes as well, such as agoraphobia (especially the type associated with having a panic attack in a place they can't escape from). It is a symptom rather than a disease, and different causes may bring it about in different individuals.
This phobia receives more attention than most other phobias because air travel is often difficult for people to avoid—especially in professional contexts—and because it is common, affecting a significant minority of the population. Inability to maintain emotional control when aloft may prevent a person from going on vacations or visiting family and friends, and it can cripple the career of a businessperson by preventing them from traveling on work-related business.
Anticipatory anxiety of being out of control and overwhelmed can prevent a person from planning to travel by air. The thought of an upcoming flight can cause great distress, particularly when compelled to travel by air. The most extreme manifestations can include panic attacks or vomiting at the mere sight or mention of an aircraft or air travel.
The fear of flying may be created by various other phobias and fears:
- Fear of crashing, which in rare cases will cause death, is the most common reason for the fear of flying.
- Fear of closed in spaces (claustrophobia), such as that of an aircraft cabin
- Fear of heights (acrophobia)
- Feeling of not being in control
- Fear of vomiting, where a person will be afraid that they'll have motion sickness on board, or encounter someone having motion sickness and have no control over it (such as escaping it)
- Fear of having panic attacks in certain places, where escape would be difficult and/or embarrassing (agoraphobia)
- Fear of hijacking or terrorism
In some cases, education can considerably diminish concern about physical safety. Learning how aircraft fly, how airliners are flown in practice, and other aspects of aviation can reduce anxiety. Many people have dealt with the problem by learning to fly or skydive, effectively removing their fear of the unknown. Some educate themselves; others attend courses offered by pilots or airlines.
Though education plays an important role, the knowledge that turbulence will not destroy the aircraft does not stop the amygdala - the part of the brain responsible for generating most emotional responses, and via the Hypothalamic–pituitary–adrenal axis, the release of stress hormones - from reacting. In turbulence, repeated downward movements of the plane trigger one release of stress hormones after another. A build-up of stress hormones can cause a person to be terrified despite having every reason to know logically that the plane is not in danger. In such cases, therapy — in addition to education — is needed to prevent the release of stress hormones so that the anxious flier may gain relief.
Behavioral therapies such as systematic desensitization developed by Joseph Wolpe and cognitive behavior therapy developed by Aaron Beck rest on the theory that an initial sensitizing event (ISE) has created the phobia. The gradually increased exposure needed for systematic desensitization is difficult to produce in actual flight. Desensitization using virtual flight has been disappointing. Clients report that simulated flight using computer-generated images does not desensitize them to risk because throughout the virtual flight they were aware they were in an office. Research shows Virtual Reality Exposure Therapy (VRET) to be no more effective than sitting on a parked airplane. As a practical substitute for systematic desensitization, the amygdala can be taught to regard a stimulus as benign by linking it to an experience already regarded by the amygdala as benign. This alternative has been termed systematic inhibition of the amygdala.
Hypnotherapy generally involves regression to the ISE, uncovering the event, the emotions around the event, and helping the client understand the source of their fear. It is sometimes the case that the ISE has nothing to do with flying at all.
Neurological research by Allan Schore and others using EEG-fMRI neuroimaging suggests that though it may first be manifest following a turbulent flight, fear of flying is not the result of a sensitizing event. The underlying problem is inadequate development of ability to regulate emotion when facing uncertainty, except through feeling in control or able to escape. According to Schore, the ability to adequately regulate emotion fails to develop when relationship with caregivers is not characterized by attunement and empathy. "Because these mothers are unable to regulate their own distress, they cannot regulate their infant's distress." Chronic stress and emotional dysregulation during the first two years of life inhibits development of the right prefrontal orbito cortex, and hinders the integration of the emotional control system. This renders the right prefrontal orbito cortex incapable of carrying out its executive role in the regulation of emotion. Some who disagree with the importance of early experience regard this view point as contentious. However, Harvard University and the National Scientific Council on the Developing Child state, "Genes provide the basic blueprint, but experiences influence how or whether genes are expressed. Together, they shape the quality of brain architecture and establish either a sturdy or a fragile foundation for all of the learning, health, and behavior that follow."
When it senses anything unfamiliar or unexpected, the amygdala releases stress hormones. In humans, stress hormones activate both the sympathetic nervous system and executive function. The sympathetic nervous system produces an urge to mobilize. Initially, to assess the situation, executive function overrides the urge to mobilize. If assessment reveals no threat, executive function dismisses the matter, and signals the amygdala to end stress hormone release. If risk is apparent, executive function considers what can be done to deal with the risk. Upon commitment to a plan, either of action or of inaction, executive function signals the amygdala to end stress hormone release.
In a non-phobic person, the arousal caused by the release of stress hormones results in a sense of curiosity, not a sense of emergency. Phobic response is significantly different. The phobic person equates arousal with fear, and fear as proof that there is danger. Upon arousal, the person's executive function is called upon not merely to assess the situation, but - if stress hormones are to be regulated - to prove no danger exists. If danger cannot be ruled out, executive function can no longer inhibit the urge to mobilize. Though phobics regard control as the antidote to fear, it is commitment to a plan - not control alone that ends the release of stress hormones. If a person has control but cannot commit to a plan, fear persists. It is interesting to note that commitment to any action - even unwise action - provides relief, and signals the amygdala to terminate stress hormone release.
If a phobic flier were able to fly in the cockpit, the pilot's facial response to an unexpected noise or motion would adequately prove the absence of danger. But with information in the cabin limited, it is impossible to prove no danger exists. Stress hormones continue to be released. As levels rise, anxiety increases and the urge to escape becomes paramount. Since physical escape is impossible, panic may result unless the person can escape psychologically through denial, dissociation, or distraction.
In the cognitive approach, the passenger learns to separate arousal from fear, and fear from danger. Cognitive therapy is most useful when there is no history of panic. But since in-flight panic develops rapidly, often through processes which the person has no awareness of, conscious measures may neither connect with - nor match the speed of - the unconscious processes that cause panic.
In another approach, emotion is regulated by what neuroscientist Stephen Porges calls neuroception. In social situations, arousal is powerfully regulated by signals people unconsciously send, receive, and process. For example, when encountering a stranger, stress hormone release increases the heart rate. But if the stranger's signals indicate trustworthiness, these signals override the effect of stress hormones, slow the heart, calm the person, and allow social interaction to take place. Because neuroception can completely override the effect of stress hormones, can be controlled by linking the noises and motions of flight to neuroceptive signals that calm the person.
Lastly, frequent flyer experts at Flightfox suggest that fear of flying is a reaction caused by the panic and tension of so many travellers in close quarters - once one person is uneasy the rest soon feel uncomfortable as well. Their solution, odd as it may seem, is to fly in premium class to experience flying in a comfortable and relaxed setting, so as to avoid the tension and anxiety of coach.
Flight experience with the use of anti-anxiety medications like benzodiazepines or other relaxant/depressant drugs varies from person to person. Medication decreases the person's reflective function. Though this may reduce anxiety caused by inner conflict, reduced reflective function can cause the anxious flier to believe what they are afraid will happen is actually happening.
A double-blind clinical study at the Stanford University School of Medicine suggests that anti-anxiety medication can keep a person from becoming accustomed to flight. In the research, two flights were conducted. In the first flight, though patients given alprazolam (Xanax) reported less anxiety than those receiving a placebo, their measurable stress increased. The heart rate in the alprazolam group was 114 versus 105 beats per minute in the placebo group. Those who received alprazolam also had increased respiration rates (22.7 vs 18.3 breaths/min).
On the second flight, no medication was given. Seventy-one percent of those who received alprazolam on the first flight experienced panic as compared with only 29% of those who received a placebo on the first flight. This suggests that the participants who were not medicated on the first flight benefited from the experience via some degree of desensitization.
Typical pharmacologic therapy is 0.5 or 1.0 mg of alprazolam about an hour before every flight, with an additional 0.5-1.0 mg if anxiety remains high during the flight. The alternative is to advise patients not to take medication, but encourage them to fly without it, instructing them in the principles of self-exposure.
September 11 implications
Flight phobia has long been a topic in the psychological and psychiatric literature, as well as in economic research. The former literature is mainly concerned with mode of travel choices after the September 11 attacks. Respondents to what extent they felt safe on planes and the number of high-risk incidents on airplanes in which they had been involved. Captain Michael (Miki) Katz, whose experience with helping nervous and claustrophobic flyers have brought him to also assume relations between fear of flying and September 11 attacks. Those who have the condition are either so paralyzed they stop flying entirely, and some continue flying but suffer intensely on each flight. In contrast, Katz said that "in countries such as in Israel as an example, where the public is much more experienced in dealing with security threats, there is no significant increase in the number of people who are afraid to fly, but the ones who were anxious to begin with have become more afraid."
Immediately after the September 11 attacks, Americans took to the nation's highways, a decision that many experts on risks said could be a fatal error. U.S. Department of Transportation data for the last three months of 2001 showed a significant increase in the number of fatal road accidents versus the same period in the year before the attacks. Because of the extra traffic, 353 more people died in traffic accidents, calculates Gerd Gigerenzer of the Max Planck Institute for Human Development in Berlin, an expert on how people respond to low-probability but high-consequence events called "dread risks." Research by Michael Sivak and Michael Flannagan showed that driving 10.8 miles on an interstate highway exposes the motorist to same risk of fatality as taking a domestic flight.
They based their findings by comparing the statistics for 10 major U.S. airlines for a 10-year period from 1992 through 2001. Airline safety has increased dramatically since that time. Based on more recent performance by U. S. airlines, the risk of taking a flight would be approximately the same as driving merely 3 miles. Since most of the risk is during takeoff and landing, Sivak and Flannagan regarded the length of the flight as relatively insignificant.
- Thelma Frye from the 1986 NBC sitcom Amen has aviophobia and the church staff takes her on a trip in a private jet to try to help her overcome her phobia.
- Marge Simpson from The Simpsons developed a severe case of aviophobia when she was a child after she learned about her father becoming "a stewardess" at an airport and actually saw him dressed up like a stewardess on one of the airplanes.
- B. A. Baracus from The A-Team was so afraid of flying that sometimes even knowing he had been on a plane caused him to fly into a rage. Since many of the unit's missions involved overseas travel, he was usually rendered unconscious before flight.
- In the 1988 film Rain Man, Dustin Hoffman's character will not fly with his brother on any airline but Qantas, forcing the pair to embark on a long road trip.
- Tom Clancy's character Jack Ryan has developed a fear of flying due to the death of his parents whose plane crashed at Chicago Midway International Airport, 19 months after his crash in Crete.
