(a)   the standards in Part B of this Schedule; and

(b)   the conditions set out in clause 3.

Note   Another Schedule may apply to the equipment in a VFR flight.

          3     For paragraph 2 (b), an EC device must not be operated in transmitting mode:

(a)   in VFR flight at or above FL290; or

(b)   concurrently with a Mode S transponder that is also transmitting ADS-B.

Note   An EC device may be operated concurrently with a Mode A/C, or a Mode S transponder (other than one that is transmitting ADS‑B) but it is not a substitute for mandatory carriage of a transponder in relevant airspace.

Part B — Standards for an EC device

          1     Subject to clauses 3 and 4, an EC device must meet the technical specifications in UK CAP 1391.

          2     An EC device must use a Class B TABS position source that complies with the performance standards specified in (E)TSO-C199, as in force from time to time.

          3     An EC device must:

(a)   be capable of transmitting a SIL value of 1, in accordance with the standards in UK CAP 1391 for an EC device that uses a Class B TABS position source; and

(b)   transmit that SIL value of 1.

          4     Despite the standards in UK CAP 1391, an EC device must:

(a)   meet the requirements described in paragraph 2.2.3.2.7.2.4.6 of RTCA/DO‑260B for transmitting an SDA of 1; and

(b)   transmit an SDA value of 1.

          5     An EC device must use a barometric encoder for altitude information.

          6     An EC device must be mounted in accordance with the manufacturer’s instructions.

          7     An EC device, when mounted in accordance with the manufacturer’s instructions, must not:

(a)   interfere with aircraft controls; or
