Abstract:
This paper details the design, hardware architecture, and operational implementation of AeroLink, a localized, low-cost wireless telemetry and voice communication system bridging a stationary Learjet 24D aircraft in an airfield hangar with an institutional Radio Navigation (RN) Laboratory. Traditional aviation training frameworks rely on high-cost hardware avionics suites or software simulations that lack physical component interfacing. To address this pedagogical gap, AeroLink utilizes a dual-node Master-Slave transceiver topology powered by ESP32 microcontrollers and nRF24L01+ PA/LNA long-range Radio Frequency (RF) modules operating on the 2.4 GHz Industrial, Scientific, and Medical (ISM) band. The framework integrates high-fidelity digital Inter-IC Sound (I2S) voice capture via an INMP441 microphone, real-time signal conditioning, and alphanumeric telemetry output reconstructed over a MAX98357A audio amplifier and a 16x2 I2C display matrix. Field evaluation demonstrates stable, noise-resistant real-time data transmission across airfield structural boundaries. The system establishes an affordable, robust instructional model for practical avionics training and embedded telemetry simulation.
