Avionics Malta Qualifications Framework (MQF) Practice Exam – Prep, Study Guide

The minimum terrain clearance set for PGCAS (Precision Ground Collision Avoidance System) in A-G CCIP (Air-to-Ground Continuously Computed Impact Point) and STRF (Strafe) modes is established at 50 feet. This clearance is critical to ensure that the aircraft maintains a safe altitude above terrain and other obstacles during operations, particularly when engaging targets.

Setting this clearance at 50 feet balances the need for situational awareness and operational effectiveness, allowing pilots to engage effectively while mitigating the risk of controlled flight into terrain. The choice of 50 feet over lower values like 25 feet reflects a precautionary measure that accounts for variances in terrain and potential inaccuracies in targeting systems or pilot inputs. Higher clearances are essential for operational safety in complex environments, and while options like 75 feet or 100 feet might seem safer theoretically, they could limit effective engagement capabilities during certain missions.
