## Introduction 

## Fuel use monitoring methods 

## SCHEDULE 2 

Article 70(2) 

1. —(1) The procedures specified in this Schedule are concerned with the monitoring of fuel use by aeroplane operators. The methods proposed are representative of the most accurate established practices. 

(2) Any equivalent procedures to those contained in this Schedule must only be allowed after prior application to and approval by the Regulator for the aeroplane operator concerned. 

## Fuel Use Monitoring Methods 

2.  The aeroplane operator, with the exception of an aeroplane operator eligible to use the CERT, must choose from the following Fuel Use Monitoring Methods— 

(a) Method A, 

(b) Method B, 

(c) Block-off/Block-on, 

(d) Fuel Uplift, or 

(e) Fuel Allocation with Block Hour. 

## Method A 

3. —(1) The aeroplane operator must use the following formula to compute fuel use according to Method A( a )—

where— 

F$_{N}$ = Fuel used for the flight under consideration (i.e. flight $_{N}$) determined using Method A (in tonnes); 

T$_{N}$ = Amount of fuel contained in aeroplane tanks once fuel uplifts for the flight under consideration (i.e. flight $_{N}$) are complete (in tonnes); 

T$_{N+1}$ = Amount of fuel contained in aeroplane tanks once fuel uplifts for the subsequent flight (i.e. flight $_{N+1}$) are complete (in tonnes); and
