"aircraft" in the event of a consecutive sequence of any two individual faults within the "fly‑by‑wire system"; and
                  b. Probability of loss of control of the "aircraft" being less (better) than 1x10‑9 failures per flight hour;
Note: 7E004.b. does not apply to "technology" associated with common computer elements and utilities (e.g., input signal acquisition, output signal transmission, computer "program" and data loading, built‑in test, task scheduling mechanisms) not providing a specific flight control system function.

7. E. 004. c. "Technology" for the "development" of helicopter systems, as follows:
1. Multi‑axis fly‑by‑wire or fly‑by‑light controllers, which combine the functions of at least two of the following into one controlling element:
a. Collective controls;
b. Cyclic controls;
c. Yaw controls;
2. "Circulation‑controlled anti‑torque or circulation‑controlled direction control systems";
3. Rotor blades incorporating 'variable geometry aerofoils', for use in systems using individual blade control.
Technical Note:
For the purposes of 7E004.c.3., 'variable geometry aerofoils' use trailing edge flaps or tabs, or leading edge slats or pivoted nose droop, the position of which can be controlled in flight.
7. E. 101. "Technology" according to the General Technology Note for the "use" of equipment or software specified by 7A101 to 7A106, 7A115 to 7A117, 7B102, 7B103, 7D101 to 7D103.
7. E. 102. "Technology" for protection of avionics and electrical subsystems against electromagnetic pulse (EMP) and electromagnetic interference (EMI) hazards, from external sources, as follows:
a. Design "technology" for shielding systems;
b. Design "technology" for the configuration of hardened electrical circuits and subsystems;
c. Design "technology" for the determination of hardening criteria of 7E102.a. and 7E102.b.
7. E. 104. "Technology" for the integration of the flight control, guidance, and propulsion data into a flight management system for optimisation of rocket system trajectory.

Category 8—Marine
8. A  Systems, Equipment and Components
8. A. 001. Submersible vehicles and surface vessels, as follows:
N.B.: For the control status of equipment for submersible vehicles, see:
a. Not used;
b. Category 6 for sensors;
c. Categories 7 and 8 for navigation equipment;
d. Category 8A for underwater equipment.
a. Manned, tethered submersible vehicles designed to operate at depths exceeding 1,000 m;
b. Manned, untethered submersible vehicles having any of the following:
1. Designed to 'operate autonomously' and having a lifting capacity of all the following:
a. 10% or more of their weight in air; and
b. 15 kN or more;
2. Designed to operate at depths exceeding 1,000 m; or
3. Having all of the following:
a. Designed to continuously 'operate autonomously' for 10 hours or more; and
b. 'Range' of 25 nautical miles or more;
Technical Notes:
1. For the purposes of 8A001.b., 'operate autonomously' means fully submerged, without snorkel, all systems working and cruising at minimum speed at which
