Combined 1991 and 1992 Robinson - 22B (R-22) Parking Test Results.

摘要

Tests were conducted in the fall of 1991 and 1992 at the Federal Aviation Administration (FAA) Technical Center to examine issues regarding rotor tip clearances for parking areas at heliports. These tests were initiated as a follow-on to previous parking tests documented in DOT/FAA/CT-TN88/30, 'Heliport Surface Maneuvering Test Results,' and DOT/FAA/CT-TN/92/1, 'Helicopter Nighttime Parking Test Results-UH-l.' Since those tests utilized a medium-size helicopter with a rotor diameter of 48 feet, similar tests were requested using a smaller helicopter with a rotor diameter of less than 30 feet. This report documents the results of these follow-on parking tests which used a Robinson-22B (R-22) helicopter. Over 480 maneuvers were conducted at the FAA Technical Center's National Concepts Development and Demonstration Heliport/Vertiport, Atlantic City International Airport, NJ. All were conducted under head, tail, and crosswind conditions, both with and without an obstacle on the helipad. Pilot subjective data, in reference to these maneuvers, were collected via post-maneuver and post-flight questions. Data collection and analysis methodology and objective, as well as subjective issues, are discussed. Statistical and graphical analysis of pilot performance and perception data are provided. Conclusions are drawn about considerations that must be given to parking clearance criteria at heliports. Heliport, Heliport parking, Rotor tip clearance.
