Lost Fuel Burn Savings

The following slides identify denied aircraft requests for climb to optimum altitudes and places a value on the increased fuel burn due to lack of FANS equipment and RNP certification

F320

Request F330

ATC Advises UNABLE higher due to Traffic

Is the traffic a Same Direction Conflict?

Is the distance between the aircraft 16nm or more?

If the these two conditions are met; Track:

Aircraft type

Feet below optimum altitude

Time the altitude request was denied

12




Request F350

ATC Clears ZZZ123 Climb and Maintain F320

Calculate time from the aircraft’s denied climb to optimum altitude.

Begin new tracking if still below optimum altitude.

13




Aircraft ZZZ123 is a B744 that was 1.5 hours and 2000 feet below optimum altitude.

133 kg per hour

Multiplied by 1.5

Equals 199.5 kg extra fuel burn for this event

Lack of RNP4 extra fuel burnData tracked for 15 days

April 1-16, 2012 Extra fuel burn of 27,331kg (60,128) lbs due to lack of FANS and RNP4

Sept 10-24, 2012 Extra fuel burn of 28,829kg (63,423 lbs) due to lack of FANS and RNP4

Jan 6-21, 2013 Extra fuel burn of 28,858kg (63,487 lbs) due to lack of FANS and RNP4

Extrapolated over a 1 year time period, an annual extra fuel burn of 702,211kg (1,544,850 lbs)

Extra 4.9 million lbs of CO2 emissions

Additional benefits are not tracked

•30nm separation after two opposite direction aircraft have passed

•If an aircraft is held below optimum altitude because of traffic and does not make requests for a new optimum altitude.

19



Additional benefits are not tracked

•Savings that could be realized by developing route systems based on a 30nm lateral standard.

•This paper only captures the lost savings for the Oakland FIR. It would be much higher if calculated for all FIRs

20



Conclusion

• The meeting is requested to:

• Recognize the benefits of RNP 4 and FANS equipage; and

• Consider certifying FANS equipped aircraft as RNP 4; and

• Consider equipping aircraft with satellite FANS and RNP 4 certification.
