Cruise is the longest and most fuel-consuming phase of flight, yet it remains one of the least optimized. While OFPs typically propose fixed flight levels at waypoints, real-world conditions — such as aircraft weight, wind, and ATC instructions — are constantly changing.

SITA OptiLevel closes this gap with proprietary digital twin technology that generates dynamic, tail-specific recommendations for optimal cruise level and speed. It uses data from the final load sheet, operational flight plan (OFP), and 4D weather forecasts to fine-tune its predictions, continuously adapting to real-time aircraft performance, environmental conditions, and operational weight, all while respecting time constraints and planned routing.

Real-time optimization of both speed and level

Real-time optimization of both speed and level

SITA OptiLevel optimizes both cruise speed and flight level in real time using tail-specific digital twin models built from over 40 performance parameters on your QAR data.

Stay on time while saving fuel

Stay on time while saving fuel

Instead of recommending the lowest fuel burn at any cost, SITA OptiLevel analyzes all possible combinations of altitude and speed to reach your destination on time with the least total fuel used. It balances efficiency with schedule performance, so you don’t have to choose between the two.

Live recommendations before and during flight

Live recommendations before and during flight

SITA OptiLevel delivers pre-flight “one-off” suggestions and real-time in-flight recommendations triggered by evolving weather conditions or aircraft position. This ensures that pilots always receive timely, fuel-saving guidance exactly when it’s most impactful.

Live flight tracking and proactive updates

Live flight tracking and proactive updates

SITA OptiLevel continuously tracks each flight in real time and proactively adjusts recommendations as conditions change. This ensures pilots always receive the most accurate, fuel-efficient guidance without needing to manually request updates — improving responsiveness, reducing workload, and maximizing in-flight savings.
