What are the three specific cases in which a fuel/energy en route alternate (ERA) aerodrome may be used according to GM30 to Annex I?

According to GM30 to Annex I, a fuel/energy ERA aerodrome may be used in the following cases: (a) 'fuel ERA aerodrome critical scenario' – used when additional fuel is required at the most critical point along the route to comply with point (c)(6) of CAT.OP.MPA.181; (b) 'fuel ERA aerodrome 3 %' – used when an operator reduces the contingency fuel to 3 %; and (c) 'fuel ERA aerodrome PNR' – used at the point of no return (PNR) during isolated aerodrome operations.

In which scenario is a fuel ERA aerodrome used at the most critical point along the route?

A fuel ERA aerodrome is used at the most critical point along the route in the 'fuel ERA aerodrome critical scenario', which is when additional fuel is required to comply with point (c)(6) of CAT.OP.MPA.181.

When does an operator use a 'fuel ERA aerodrome 3 %'?

An operator uses a 'fuel ERA aerodrome 3 %' when the operator reduces the contingency fuel to 3 %.

During which type of operations is a 'fuel ERA aerodrome PNR' used?

A 'fuel ERA aerodrome PNR' is used at the point of no return (PNR) during isolated aerodrome operations.

Which specific requirement in CAT.OP.MPA.181 is referenced in the definition of a fuel ERA aerodrome critical scenario?

The definition references point (c)(6) of CAT.OP.MPA.181, which concerns the fuel/energy scheme – fuel/energy planning and in-flight re-planning policy – for aeroplanes.

FUEL/ENERGY EN ROUTE ALTERNATE (ERA) AERODROME

Fuel/energy ERA aerodromes could be used in the following cases:

(a) ‘fuel ERA aerodrome critical scenario’: that aerodrome is used when additional fuel is required at the most critical point along the route to comply with point (c)(6) of point CAT.OP.MPA.181 ‘Fuel/energy scheme — fuel/energy planning and in-flight re-planning policy — aeroplanes’;

(b) ‘fuel ERA aerodrome 3 %’: that aerodrome is used when an operator reduces the contingency fuel to 3 %; and
