How do you minimize and manage display latency in flight deck systems?

Display latency (time from sensor data to pilot perception) affects control and situational awareness. Latency sources: Sensor sampling and processing, Data bus transmission, Symbol generation and rendering, and Display scan time. Target: <100ms end-to-end for primary flight data, <200ms for enhanced vision. Minimization strategies: High sensor sample rates with extrapolation, Prioritized data routing (AFDX virtual link scheduling), Efficient graphics pipeline (dedicated GPU, optimized drawing), LCD panel selection (response time <10ms, high refresh rate), and Predictive algorithms for display update. Measurement: End-to-end latency measurement with instrumentation, Compliance with DO-331 display requirements. Special considerations: Head-up display latency critical for landing, Enhanced/synthetic vision requires careful registration with outside world, and Touch input latency for pilot interaction.
