Aircrew Vision Requirements: trainer
Minimum external vision angle requirements from the pilot's design eye position per MIL-STD-850B (3 November 1970). Covers all military aircraft types — fighter/attack (single/tandem and side-by-side), bomber/transport, ASW/patrol, helicopter (side-by-side and single/tandem), V/STOL, and trainer. Vision angles (degrees down and up from horizontal) are specified at discrete azimuth positions (0–135 deg) and are mandatory minimums; values between specified azimuths increase progressively. Also encodes structural post/frame width limits (projected inches) as constraint records. Reference angles are measured from the pilot's horizontal vision plane relative to the aircraft longitudinal fuselage reference line; azimuth zero is straight ahead. Symmetry note: side-by-side requirements for the pilot apply to the copilot with azimuths reversed (per 4.1.4). 43 records.
