19  General equations
 (1) The emissions intensity for an aircraft for a phase on a route, in tonnes CO2‑e per service unit, for a particular period is worked out using the formula (equation 8):
where:
I means the emissions intensity for the aircraft for the phase on the route, in tonnes CO2‑e per service unit, for the period.
E means the total emissions for the aircraft for the phase on the route for the period, in tonnes CO2‑e, worked out using equation 10.
QS means quantity of service provided by the aircraft for the phase on the route during the period determined in accordance with the monitoring requirements.
 (2) The emissions intensity for a particular energy source for an aircraft for a phase on a route, in tonnes CO2‑e per hour, for a particular period is worked out as follows (equation 9):
where:
I means the emissions intensity for the energy source for the aircraft for a phase on the route, in tonnes CO2‑e per hour, for the period.
E means the total emissions for the aircraft for the phase on the route when using the energy source for the period, in tonnes CO2‑e, worked out using equation 10.
t means the time in hours that the aircraft used the energy source in the phase on the route during the period determined in accordance with the monitoring requirements.
 (3) The total emissions for an aircraft for a phase on a route for a particular period, in tonnes CO2‑e, is worked out using the formula (equation 10):
where:
E means the total emissions for the aircraft for the phase on the route for the period, in tonnes CO2‑e.
EF means the emissions for the aircraft for the phase on the route for the period from transport fuel use, in tonnes CO2‑e, worked out using equation 11.
EEC means the emissions for the aircraft for the phase on the route for the period from consumed electricity used to operate the aircraft, in tonnes CO2‑e, worked out using equation 12.
 (4) The emissions for an aircraft for a phase on a route for a particular period from transport fuel, in tonnes CO2‑e, is worked out using the formula (equation 11):
where:
EF means the emissions for the aircraft for the phase on the route for the period from transport fuel, in tonnes CO2‑e.
EF,i,j means emissions for the aircraft and its auxiliary equipment for the phase on the route from fuel type i of greenhouse gas j, in tonnes CO2‑e, worked out using the formula:
where:
QF,i means the quantity of fuel type i used to operate the aircraft and its auxiliary equipment for the phase on the route during the period in
