Why manage fuel efficiency?
SME airline Flight
Operations Efficiency
Two years as a core
member of the IATA
Green Teams
Two years as Fuel
Efficiency Lead at LOT
Polish Airlines
Four years with the
Etihad Airways Group
6. Small Margins: example: the cost-profit delta is only USD
457 (3.6%)... inefficiencies drop that to USD 50 (0.4%)
(use case: SouthWest airlines, example only)
Every Kilo Counts!
7. Fuel Management & Flight Safety
•The number-1 priority is Flight Safety
•Less fuel does not mean that the operation is less safe!
Airlines that operate more efficiently are considered
safer operations, because of:
• Increased Situational Awareness
• Increased Accuracy / Tailored Tools
• Specific Training & Management Support
•Fuel Efficiency is not about taking fuel away; the aim is
to right-size the fuel planned and on board for each
individual flight.

9. How To Start?
• Know-how in fuel efficiency
• Organization, processes,
senior management support
• Tools, software to support the
fuel efficiency program
• Kick Start: Consulting Support
Know-How
Organization
Tools
Support
10. How to start: Organisation
• Clear will, mandate, and support from Senior Management to save fuel;
• Strong and empowered fuel efficiency team, consisting of people from
all areas of the airline
• Following the principles of change management related to internal
communication and stakeholder involvement
• Executive Commitment
• Focus on priority projects
• Use proven methods and tools
• Leverage success
• Measure the improvements
• Sustain and Control the improvements
11. How to start: Tools & Software
• Traditionally, airlines use Excel or simple database solutions,
while having limited or partial data
• A fuel efficiency manager or team spent/wasted a lot of time
with collecting data, checking and fixing problems in the data,
and “playing with Excel” to get the required analyses
• In the meantime excellent software tools became available –
we call such a tool a Fuel Management Information System, or
FMIS
• Vendors are Honeywell, OpenAirlines, Boeing, Rolls Royce,
General Electric, Sagem, and a few niche players
12. A Fuel Budget – Do You Have Any Idea?
• Fleet physical data (aircraft types, numbers)
• Fleet operational data (cycles, block/flight hours)
• Aircraft type fuel burn data (average)
• Fuel price (average for the year)
Task: Create a fuel budget (1 year) to see the critical numbers!
Required:
2 snapshots, 12 weeks apart: 16% UP, significant IMPACT! (Obvious one?)
18. More Data & Information
With the basics, now is the time to derive the important
parameters:
• The narrow-body fleet operates 48.5% of the flights but burns
only 12.4% of the fuel (which means focus on what?)
• APU burn is 1.0 % of total burn (± 33,000 tons / USD 23M)
• Taxi burn is 1.6 % of total burn (± 53,000 tons / USD 33M)
1% of this fuel budget means USD 23 M saved!
How? It starts with AWARENESS and CAMPAIGNING
19. Cost of Weight
CoW can be derived using the Breguet Range Equation (more accurate) or
using actual fuel burn versus landing weight data (easier). Typical plot:
In this example the
fleet average CoW
factor is 3.02% (the
y-value).
Results vary with
aircraft sub-types
and sector lengths,
and will be visible
when filtering for
these inputs.
CoW-TOW vs LW
20. More Data & Information
Cost of Weight: now that we have an idea about the numbers, we
can calculate the CoW:

Mission Management Flight Planning is critical and must support
integration of all Costs- Fuel / Time / Airspace / Delay
Airlines are in the business of burning fuel!
• Fuel is burnt to meet Business Requirements at lowest overall Cost
• Meeting required/revised arrival time at balanced cost
• Mitigating Delay Costs vs. Minimizing fuel burn
• Vital: Flight Documentation must be trustworthy; Flight Crews & Flight
Planners are team members!
28. More Data & Information

Integrity
29. More Data & Information
Air Traffic Management: Major impact on Network Operations Efficiency,
especially when operating a hub-and-spoke system out of a single Hub

Meteorology: Potential impact, worth investments
Thought- the Aviation Industry is the only Industry that in most countries
fully pays for its own infrastructure.
It is only fair that this infrastructure (ANSPs, Airports) is as efficient as it
can be. Demand optimization!
