Glossary Of Terms

AA refers to Alcoholics Anonymous, a peer self-help program for those who have a desire to stop drinking based on a 12-step program. While having demonstrated therapeutic benefits, AA is not therapy in a clinical sense, but is instead a peer support group. AA became a model for developing self-help programs for other types of addiction including CA - Cocaine Anonymous, NA - Narcotics Anonymous, and SA - Sexaholics Anonymous.

Aftercare is an imprecise and somewhat dated term that is most commonly used as a synonym for Continuing Care (see below). Aftercare has also been used to describe clinical group therapy, and is sometimes used to mean the continuing care and monitoring aspects of a HIMS program that follow discharge from the treatment facility. Because of the variations in meaning associated with it, use of this term is discouraged.

ALPA refers to the Air Line Pilots Association, principle partner in the development of HIMS.

AMAS refers to the Aviation Medicine Advisory Service, a company which provides medical guidance to aviators and which has been historically tasked by ALPA to assist in executing the federal HIMS contracts.

AME refers to Aviation Medical Examiner, physicians who have undergone training and are FAA approved to issue pilot medical licenses.

BAC refers to Blood Alcohol Content and is commonly expressed as milligrams percent of ethanol per deciliter of blood.

Birds or BOAF refers to Birds Of A Feather International, an organization based on the principles of AA whose membership is limited to pilots. Breathalyzer is a term used to describe a variety of testing devices that measure BAC by analyzing the amount of ethanol exhaled by the subject.

CDT refers to the Carbohydrate Deficient Transferrin test. This blood test is a good diagnostic tool for differentiating between chronic, heavy drinking subjects and light social drinkers. It is not an effective tool for verifying abstinence.

CFR refers to Code of Federal Regulations.

Continuing Care refers to the aspects of the post-residential treatment recovery program that are directly related to healthcare. Group therapy, meetings with the AME, individual counseling, family therapy, relapse prevention treatment, and AA/NA meetings are included in this group.

DOT refers to the US Department of Transportation.

Drug Screen refers to a variety of testing methods used to identify drug ingestion. Urine screens include tests for different classes of drugs and each class is analyzed using a particular “panel.” DOT testing utilizes a 5-panel test. Abstinence compliance testing is typically a 10 or 12-panel test. Other methods of testing include hair and nail samples. The detection window varies depending on the drug consumed and the method of testing that’s employed.

Dx is medical shorthand for Diagnosis.

EtG refers to the Ethyl Glucuronide, a specific direct biomarker of ethanol ingestion. EtG urine testing is very sensitive and may be positive due to incidental alcohol exposure such as through the use of mouthwash, over-the-counter medications, or other consumer products. The detection window for ETG tests is typically 1 to 2 days.

EtOH is the chemical name for ethyl alcohol.

EtS refers to Ethyl Sulfate, another specific direct biomarker of ethanol ingestion. Like EtG, EtS urine testing is very sensitive and can be positive due to incidental alcohol exposure. The detection window for EtS is also 1 to 2 days.

FAA refers to the US Federal Aviation Administration, a component of the DOT.

FAR refers to the Federal Aviation Regulations.

Group Therapy as used by FAA and HIMS refers to clinical group therapy, i.e. group therapy led by a trained clinician.

Part 121 refers to the portion of the FAR’s that deals with mainline commercial passenger aircraft operations.

Part 135 refers to the portion of the FAR’s that deal with commuter and charter aircraft operations.

PEth refers to Phosphatidylethanol tests. PEth is a direct biomarker blood test that is considered an extremely accurate indicator of steady moderate and binge-type consumption. The test, while accurate, is not particularly sensitive to low levels of consumption. However, it is quite specific for EtOH, with no known false positives, and increases the detection window of a binge-type relapse for up to 3 weeks.

Pilot Assistance or PA is a general term used to refer to pilot occupational assistance programs dealing with issues such as addiction, depression, stress management, and physical illness.

PWA refers to Pilot Working Agreement: the formal, comprehensive written agreement between a pilots’ union group and the employer.
