ED Decision 2022/007/R
(a) Combined vision systems (CVSs) combine a real-time imaging sensor and a display with a synthetic image generated using a terrain, runway and obstacle database, and a precision navigation position.
(b) A CVS shall comply with the requirements of the respective certification specifications for the images that are generated, and in addition shall ensure that:
(1) the images are conformal with each other;
(2) the images are aligned within 5 mrad laterally and vertically at the boresight of the display;
(3) the images do not cause confusion to the flight crew; and
(4) significant image discrepancies due to failure conditions are obvious to the flight crew.
(c) If a HUD (or equivalent display) is used to display the images, then it shall meet the performance and integrity requirements applicable to the intended type of operation. Refer to CS-AWO Subpart B Section 2 SA CAT I, Section 3 CAT II or Section 4 CAT III.
(d) CVSs that are used for operational credits shall also meet the requirements that apply for EFVSs or SVGSs.
