and
 (iii) altitudes for flight with one-engine-inoperative and depressurised conditions; and
 (iv) holding altitudes; and
 (b) detailed all-engines-operating performance data, including fuel flow data, for ISA and ambient conditions as a function of airspeed and power setting, encompassing:
 (i) cruising altitudes; and
 (ii) altitudes for flight under depressurised conditions; and
 (iii) flight at 10 000 ft above mean sea level; and
 (iv) holding altitudes; and
 (c) any available data related to any other conditions relevant to the EDTO flight that could result in a significant deterioration to the performance of the specific airframe/engine combination, including the following conditions:
 (i) ice accretion on the aeroplane surfaces not encompassed by anti‑ice or de‑ice systems;
 (ii) if required to be considered by the aeroplane's manufacturer as part of the EDTO airworthiness certification of the aeroplane:
 (A) the ram air turbine deployment; and
 (B) the thrust reverser deployment.
 (6) For paragraph (4)(b), the altitudes, airspeeds, thrust settings and fuel flow, used in establishing the EDTO area of operations for the airframe/engine combination, must be used when determining whether the requirements in sections 9.07 and 9.08 can be met for an EDTO flight of the aeroplane.
Note: Sections 9.07 and 9.08 provide for obstacle clearance performance requirements for the en route phase of a flight.

2.19  Dispatch requirements for EDTO beyond 180 minutes
 (1) This section applies in relation to an EDTO flight conducted beyond a maximum diversion time of 180 minutes.
 (2) The following systems of the aeroplane must be serviceable for dispatch:
 (a) if the aeroplane is a 2‑engine aeroplane—the auto-throttle system;
 (b) if required:
 (i) by the aeroplane manufacturer for one-engine-inoperative, or depressurisation, procedures; or
 (ii) for a time-limited system (if any);
  the auxiliary power unit, including electrical and pneumatic supply to its designated capability;
 (c) a communication system, in addition to any such equipment required for the aeroplane under Chapter 11, that is capable of providing effective direct communication (for example, by voice, SATCOM/SATVOICE or ACARS) between the flight crew and air traffic services, and between the flight crew and either or both the operations control and flight dispatcher.

2.20  In‑flight operational procedures for EDTO

Significant changes to be evaluated
 (1) A significant change:
 (a) in forecast weather; or
 (b) in the aerodrome availability for the flight; or
 (c) in the required services at any EDTO en-route alternate aerodromes designated for the flight;
that occurs during an EDTO flight of an aeroplane and before the aeroplane proceeds beyond the EDTO entry point, must be evaluated by the pilot in command as soon as practicable.
 (2) If a significant change mentioned in subsection (1) would prevent a safe approach and landing at an EDTO en-route alternate aerodrome during the estimated time of
