Flight Director & Course Control System

Mi-8 / Mi-17 flight director and course-control equipment is arranged for searches based on an exact avionics designation and version. The category contains complete-system references, receiver and indicator units, control blocks, amplifiers, switching assemblies and internal modules recorded for navigation and guidance equipment. Because several families use similar prefixes, the complete identifier is essential from the first search.

A-034, A-037 and course-equipment families

Product records include A-034 and A-037 executions, ARK-9, ARK-UD, RV-5M variants, Prima-KV, PP-5M versions and other units. Some entries describe a full equipment family while others identify one constituent block or assembly. Their catalogue relationship supports discovery only and does not prove that two versions have identical interfaces or operational roles.

Version numbers separate closely related units

A suffix, version number or drawing reference may distinguish the location, connector arrangement, electrical execution or place within a set. Retain Latin or Cyrillic characters exactly as documented and include the complete system name when it is known. Resolve mixed markings by comparing the label with the aircraft equipment list and the applicable maintenance documentation.

• copy every character of the unit designation;
• state the installed navigation or guidance equipment family;
• identify the helicopter model and modification;
• list the required unit, set or internal assembly;
• send quantity, document requirements and label photographs.
