Overview

PSTOL Flaps are the pinnacle of performance tailored to meet the high demands of skilled backcountry pilots. These flaps revolutionize wing aerodynamics, altering wing camber and angle of attack during glide path deployment. Designed to resolve the longstanding challenge of obscured sightlines during short landings in confined areas, PSTOL Flaps significantly lower deck angles, enhancing visibility for safer and more controlled landings.

The meticulously engineered slot design ensures uninterrupted airflow and prevents boundary layer separation, leading to improved flap effectiveness. The deployment of PSTOL Flaps results in remarkable benefits, including a reduction in landing and stall speeds by an average of 3-5 mph, a noticeable increase in maximum drag and lift as compared to standard flaps, and a pronounced increase in wing camber and chord line steepness.

Installation of PSTOL Flaps calls for expertise, with an IA required for certified installations due to necessary fabric work. Estimated installation time ranges from 20 to 30 hours, contingent on the mechanic's proficiency. While compatibility is restricted for certain fuel tank configurations, PSTOL Flaps offer an exceptional solution for those who seek enhanced short-landing performance without compromising safety or precision.

Technical Specs

Features

Aerodynamic Innovation optimizes airfoil geometry during deployment, dynamically altering wing camber and angle of attack to significantly augment short landing characteristics.

Observational Enhancement achieves decreased deck angles upon activation, leading to increased forward visibility crucial for navigating confined landing areas with precision.

Performance Amplification yields a discernible decrease in both landing and stall speeds by an average range of 3 to 5 mph, accompanied by amplified lift and drag coefficients, owing to the augmenting wing camber and chord line.

Flap Efficiency Optimization is ensured through an ingeniously designed "slotted" or "fowler" configuration that guarantees continuous airflow and eradicates boundary layer separation, thereby substantially enhancing aerodynamic effectiveness.

Enhanced Sightline Strategy effectively addresses the visual impairment challenge faced during short landings in constrained zones, culminating in heightened pilot assurance during touchdown spotting.
