Summary
Wheelchair safety in air travel is being researched. Studies show that wheelchairs meeting motor vehicle safety standards (WC19) may be safely used on airplanes with proper restraints, improving accessibility.
Area of Science:
- Biomechanics
- Aerospace Engineering
- Rehabilitation Engineering
Background:
- Current commercial air travel regulations prohibit passengers from using their personal wheelchairs during flight.
- Existing airline seating solutions may not adequately address the diverse medical and accessibility needs of passengers with mobility impairments.
Purpose of the Study:
- To evaluate the safety and crashworthiness of wheelchairs compliant with RESNA Voluntary Standard WC19 for potential use as aircraft seating.
- To determine if WC19-compliant wheelchairs, when secured with four-point tiedowns, can meet Federal Aviation Administration (FAA) aircraft seating safety standards.
Main Methods:
- Computer modeling was used to simulate FAA horizontal impact testing, assessing the adequacy of a trapezoidal sled pulse and the minimal effect of pitch/roll.
- Horizontal impact tests were conducted on WC19-compliant wheelchairs secured with four-point tiedowns.
- Modifications, including the addition of a vehicle-mounted lap belt, were implemented for subsequent tests after initial caster fractures.
Main Results:
- Computer modeling confirmed the suitability of a trapezoidal sled pulse for simulating aircraft impact conditions.
- Initial testing revealed a fracture in the left front wheelchair caster.
- Five wheelchairs, with an added lap belt, successfully met occupant retention and structural integrity requirements during testing.
Conclusions:
- WC19-compliant wheelchairs can potentially be used safely for air travel, meeting aircraft safety standards with appropriate securing methods.
- The addition of a vehicle-mounted lap belt was crucial for achieving successful test outcomes.
- This research suggests a viable pathway to enhance accessibility and safety for wheelchair users in commercial aviation.

01:24Normal and Tangetial Components: Problem Solving
Consider a man with a mass of 70 kg seated in a chair connected to a pin support through a member BC. If the man maintains an upright position, the task is to determine the horizontal and vertical reactions of the chair on the man when the member makes a 45° angle with the horizontal. At this moment, the man has a speed of 5 m/s, increasing at a rate of 1 m/s².
00:55Composite Bodies
A composite body is a body made up of multiple parts, connected to form a larger, unified object. Each part has its own weight and center of gravity, which must be considered to determine the center of gravity of the composite body. In cases where the density or specific weight is constant, the center of gravity coincides with the centroid.
