GUIDELINES FOR DIVERSION PROCEDURE
Applicable to: ,
Complete ‐ the related failure procedure.
‐ Inform ATC.
‐ Initiate the descent.
‐ Determine which en route alternate is the most suitable one (per company procedure).
‐ Divert to the chosen en route alternate.
‐ Comply with the pre-planned diversion strategy and speed schedule, or adjust the speed
schedule, as dictated by the evaluation of the actual situation.
Note: For detailed guidelines and procedures for conducting the diversion (lateral and vertical
navigation), see chapter DSC 22.20.60, the FMGS Pilot’s Guide.
DIVERSION PERFORMANCE DATA
Applicable to: ,
Chapter PRO, CRZ, OEI gives three single engine descent and cruise procedures :
1. The standard strategy.
2. The obstacle strategy.
3. Fixed speed strategies (ETOPS).
For ETOPS operations, any one of the above diversion strategies can be used provided that the
selected strategy and speed schedule are used in :
• establishing the area of operation (maximum diversion distance),
• calculating the diversion fuel requirements for the single-engine ETOPS fuel scenario.
• demonstrating the applicable obstacle clearance requirements (net flight path and net ceiling).
During the diversion, the flight crew is expected to use the planned speed schedule. However, based
on the evaluation of the actual situation, the pilot in command has the authority to deviate from this
planned one-engine-inoperative speed.
DIVERSION DECISION MAKING
Applicable to: ,
The technical criteria governing a re-routing or diversion decision can be classified into four
categories, as follows :
Loss of MNPS capability, before entering ‐ the MNPS area (as applicable).
‐ Weather minima at diversion airport(s) going below the company/crew en-route minima, before
reaching the ETOPS Entry Point, or diversion airport(s) becoming unsuitable for any reason.

FCOM 19 AUG 10
‐ Failure cases requiring a diversion to the nearest airport (cases leading to a LAND ASAP message
on the ECAM and/or in the QRH).
‐ Failure cases resulting in increased fuel consumption, exceeding the available fuel reserves.
Comments and recommendations
• Electrical generation
Diversion is required in case of :
‐ only one generator (either one IDG, APU GEN or EMER GEN) remaining available following a
multiple failure,
‐ only one main generator (either one IDG or APU GEN) remaining available and green hydraulic
circuit low level.
• Fuel system
Some failure cases may lead to fuel gravity feeding which implies flight at lower altitude or to some
fuel being unusable. The flight crew’s evaluation of the actual situation and the fuel remaining may
lead to the decision that a diversion is required.
