Saving Jet Fuel

Saving Jet Fuel. Saving Jet Fuel A Boeing 787-9 Dreamliner flying nonstop from Newark Liberty International Airport (EWR) to Leonardo da Vinci-Fiumicino Airport (FCO) could need $68K in jet fuel over the 8.

What happened

Adjusting the flight path for wind conditions could reduce fuel consumption and possibly save a few thousand dollars. Firms like Jeppesen have offerings in this space, but Scikit-decide, together with a narrow- and wide-body fuel consumption model built by a professor at the Delft University of Technology and wind data from NOAA, offer an open source solution. Scikit-decide's optimal flight path solver can be configured to use different fuel consumption models. In this post, I'll compare two flight paths flown using the Airbus A320 and OpenAP's fuel consumption model.

The wider picture

The retirement savings structure allows members to access a portion of their savings without cashing out their entire pension. Scikit-decide has been in development for six years. It's a framework for reinforcement learning, automated planning and scheduling. The project can optimise flight paths, re-organise airline workforce schedules and calculate drone swarm paths. OpenAP is an aircraft performance model and toolkit developed by Dr. Sun has a PhD in air traffic management and, among many other things, teaches a course on the subject as a tenured assistant professor at TU Delft in the Netherlands.

It has a liquid cooler attached and is housed in a spacious, full-sized Cooler Master HAF 700 computer case. The system has 96 GB of DDR5 RAM clocked at 4,800 MT/s and a 5th-generation, Crucial T700 4 TB NVMe M.

What has been reported

2 SSD which can read at speeds up to 12,400 MB/s. There is a heatsink on the SSD to help keep its temperature down. The system is powered by a 1,200-watt, fully modular Corsair Power Supply and is sat on an ASRock X870E Nova 90 Motherboard. I'm running Ubuntu 24 LTS via Microsoft's Ubuntu for Windows on Windows 11 Pro. In case you're wondering why I don't run a Linux-based desktop as my primary work environment, I'm still using an Nvidia GTX 1080 GPU which has better driver support on Windows and ArcGIS Pro only supports Windows natively.

12 along with jq in this post. $ sudo add-apt-repository ppa:deadsnakes/ppa $ sudo apt update $ sudo apt install \ jq \ python3-pip \ python3. 12-venv I'll set up a Python Virtual Environment and install scikit-decide, along with the OpenAP open aircraft performance model and OpenTop, a flight trajectory toolkit that was also developed by Dr. Sun. $ python3 -m venv ~/. flight_planning $ source ~/. flight_planning/bin/activate $ pip install \ 'scikit-decide[all]' \ 'openap[all]' \ opentop The above will need at least 8 GB of storage capacity.
