WELCOME TO REIVON

A Clean Sky Technology Evaluator project.

We aim to investigate to what extent the CO2 emissions of global aviation can be reduced via an optimisation of aircraft size/range and flight network through: 1) splitting long-haul flights into shorter legs; 2) reducing frequencies to the necessary minimum; and a combination of 1 and 2 with related aircraft optimization. Objectives – Investigate CO2 savings and possible intermediate stops – Explore stakeholder impacts: airlines, airports, ANSPs, passengers, manufacturers, airport neighbours

REIVON APPROACHES

1 splitting long-haul flights into shorter legs 
2reducing frequencies to the necessary minimum

Split flight into shorter legs with optimised aircraft

Split flight with optimised aircraft

Avoid «burning fuel to carry fuel»

Additional fuel for
second take-off

Avoid «burning fuel to carry fuel»

SPLIT FLIGHT WITH OPTIMISED AIRCRAFT

Fewer flights with larger aircraft

ISO:
Reducing “burning fuel to carry fuel” Second take-off
Savings through optimised aircraft design

LARF:
Comparing many small vs few large aircraft flights
With today’s vs optimised aircraft

REIVON Main Approach 1A:

Split long-haul flights into shorter legs (intermediate stop operations = ISO)

REIVON Main Approach 1B:

Split long-haul flights into shorter legs (intermediate stop operations = ISO)

REIVON Main Approach 2:

Fly larger & range optimised aircraft with reduced frequencies

MISSION

– Investigate CO2 savings and possible intermediate stops;

– Explore stakeholder impacts: airlines, airports, ANSPs, passengers, manufacturers, airport neighbours;
