LCA AF Mk2 performance update: The Aeronautical Development Agency has started an important step before the first flight of the LCA AF Mk2. The team has put out a tender asking for a full update of the aircraft’s performance models. This work will help them check how the jet will fly, how strong the engine will act, and how the aircraft will respond in the first set of flight tests.
The tender lists 6 big jobs that must be done so engineers can understand the jet’s flight behaviour, limits, and engine reactions before the real tests begin.

A. Aerodynamic Data Set for AF Mk2
The first job is to make a complete aerodynamic data set for the fighter. This means gathering and improving all the numbers that describe how air pushes on the aircraft at different speeds and heights. These values will help engineers predict performance, adjust control laws, and clear the jet for safe test flights, reported IDRW.
B. Propulsion Data Set for AF Mk2
The next job is to build a detailed propulsion data set for the GE F414 engine inside the new AF Mk2 design. This includes studying how the engine gives thrust, how fast it reacts, how much fuel it uses, and how hot it gets in different flying conditions. Good engine modelling is needed to know how the jet will accelerate, climb, take off, and handle during early tests.
C. Development of Aircraft Performance Prediction Model for First Block of Flights
With the ADS and PDS ready, the chosen vendor will build a performance-prediction model made just for the first set of test flights. This model will act like a “virtual jet” and show how the aircraft might behave in real life. It will simulate things such as:
- Take-off and landing distances
- Rate of climb and maximum achievable altitudes for early flights
- Acceleration and deceleration profiles
- Sustained and instantaneous turn performance within initial limits
- Fuel burn estimates and endurance predictions
Such a model allows ADA to plan safe, structured flight envelopes while providing test pilots with validated performance expectations.
D. Preparation of Aircraft Performance Charts for First Block of Flights
These charts usually show things like:
- Speed-altitude envelopes
- Thrust and drag curves
- Climb performance tables
- Stall margins and AoA boundaries
- Turn-performance diagrams
Performance charts form the backbone of pre-flight planning during early developmental flight testing.
E. Coordination of Flight Testing Activities for First Block of Flights
The vendor will also help during the flight tests and work closely with all the groups involved. This means they will stay in touch with the simulation team, the flight-test engineers, the telemetry crews, and the pilots so everything runs smoothly without any confusion.

This coordination includes:
- Pre-flight briefings based on predictive models
- Ensuring data requirements are met
- Supporting anomaly analysis
- Providing real-time and post-flight feedback loops
- This ensures the flight-test campaign remains safe, structured, and data-driven.
F. Updating Aircraft Performance Model Using Flight Data
When the AF Mk2 finally starts flying in real tests, the team will change and fix the performance model again using the data collected from those flights. This last step makes sure the computer simulations match what the jet actually does in the air. This helps with:
- Enhanced fidelity of performance predictions
- Progressive envelope expansion
- Accurate calibration of aerodynamic and propulsion models
- Reliable planning for subsequent test phases and production clearance
- Flight data-driven refinement is critical for advancing from prototype testing to the certification and production stages.
The tender shows that ADA is now moving into the stage where they must check and fine-tune everything before the LCA AF Mk2 can fly. This new version of the jet has a stronger engine, a bigger body, more fuel space, and the ability to carry more weapons. Because of these upgrades, the aircraft is getting close to the test-flight phase.
