Inflight Monitoring for Pilots with Diabetes

FAA Protocol for Airmen: IDDM while Airborne

Apr 2014

Guidance is compiled and interpreted by professional pilots and physicians at from the 2014 AME Guide pages 208-209, FAA and FDA web data ( &, instructions specified in the Aeronautical Information Manual, Federal Air Surgeon Bulletins from 1999-2015, and 14 CFR Part 61 and Part 67 (the FARs).

Pilots with Insulin Dependent Diabetes

Monitoring and Actions Required During Flight Operations

FAA Considerations
Disease Protocols - Insulin Treated Diabetic Pilots

To ensure safe flight, the FAA requires that the insulin using diabetic airman must carry during flight a recording glucometer; adequate supplies to obtain blood samples; and an amount of rapidly absorbable glucose, in 10 gm portions, appropriate to the planned duration of the flight. The following actions shall be taken in connection with flight operations:

  • One half hour prior to flight, the airman must measure the blood glucose concentration. If it is less than 100 mg/dl the individual must ingest an appropriate (not less than 10 gm) glucose snack and measure the glucose concentration one half hour later. If the concentration is within 100 -- 300 mg/dl, flight operations may be undertaken. If less than 100, the process must be repeated; if over 300, the flight must be canceled.
  • One hour into the flight, at each successive hour of flight, and within one half hour prior to landing, the airman must measure their blood glucose concentration. If the concentration is less than 100 mg/dl, a 20 gm glucose snack shall be ingested. If the concentration is 100 -- 300 mg/dl, no action is required. If the concentration is greater that 300 mg/dl, the airman must land at the nearest suitable airport and may not resume flight until the glucose concentration can be maintained in the 100 -- 300 mg/dl range. In respect to determining blood glucose concentrations during flight, the airman must use judgment in deciding whether measuring concentrations or operational demands of the environment (e.g., adverse weather, etc.) should take priority. In cases where it is decided that operational demands take priority, the airman must ingest a 10 gm glucose snack and measure his or her blood glucose level 1 hour later. If measurement is not practical at that time, the airman must ingest a 20 gm glucose snack and land at the nearest suitable airport so that a determination of the blood glucose concentration may be made.

FAA Note: Insulin pumps are acceptable.
