This technical report is geared towards clinicians that prescribe bifocal spectacles for Army aviators. The bifocal add required to pass the Flight Duty Medical Examination (FDME) is based on a 14 - inch testing distance and is often too strong for use in the cockpit. Cockpit working distances are generally 18 to 36 inches. This guide provides the clinician with more information about the expected near working distances in specific Army aircraft. A description of each aircraft, a diagram of the cockpit layout, distances to each of the control panels and the Snellen equivalent letter size of instrumentation is detailed. The final part of the paper uses an example to aid in determination of the operationally-optimal bifocal add power and segment height.
