Roles and Responsibilities

As a Flight Mechanics Engineer (verification and validation), the following work area and skill sets awaits you:

1. Aircraft Flight Mechanics & Dynamics

  • Test the 6-DOF nonlinear aircraft flight-dynamics models to their 

  • Develop mathematical models for aircraft rigid-body dynamics, aerodynamics, propulsion, actuators, landing gear, and environmental effects.

  • Perform aircraft trim, stability, control, and performance analyses across the flight envelope.

  • Determine and analyse aerodynamic derivatives, stability derivatives, control derivatives, and propulsion characteristics.

  • Perform longitudinal, lateral, and directional stability and controllability assessments.

  • Analyse control-system performance, stability margins, actuator utilisation, and control authority.

  • Run Software-in-the-Loop (SIL) and Hardware-in-the-Loop (HIL) iron-bird, and flight-test simulations.

  • Compare simulation results against flight test or analytical data and generate reports.

  • Design test cases, write test scripts and verification procedures etc..

2. Modelling & Simulation

  • Develop and maintain testing environments using MATLAB/Simulink, Python, C/C++, or equivalent tools.

  • Test and mature the aircraft, propulsion, actuator, sensor, environment, and flight-control models.

  • Perform model correlation against wind-tunnel, component-test, ground-test, and flight-test data.

  • Establish model validation processes. 

  • Evolve aircraft response characteristics such as Time constants, Natural frequencies, Control response, Hover and transition response etc.

  • Develop and simulate failure, fault, and degraded-mode scenarios.

  • Support FHA, FMEA, FTA, SSA, and system safety activities from a flight-dynamics perspective.

3. Flight-Test & Data Analysis

  • Analyse flight-test data and correlate simulation predictions with actual aircraft behaviour.

  • Investigate discrepancies between simulation, ground-test, and flight-test results.

4. Certification & Technical Documentation

  • Support preparation of engineering analyses and compliance evidence as per certification requirements.

  • Prepare technical reports, analysis notes, model documentation, simulation reports, and verification evidence.
