- Appendix A — Guidance Respecting Headsets and Corded Devices
(1) This Advisory Circular (AC) is provided for information and guidance purposes. It describes an example of an acceptable means, but not the only means, of demonstrating compliance with regulations and standards. This AC on its own does not change, create, amend or permit deviations from regulatory requirements, nor does it establish minimum standards.
(1) The purpose of this AC is to advise operators of the potential hazards associated with:
- (a) passenger use of personal headsets during taxi, take-off, descent and landing and while walking on the apron to and from the aircraft; and
- (b) The installation and use of corded electrical devices in the passenger cabin.
(2) The intent of this AC is to consolidate and clarify policy, and provide guidance to operators regarding the use of personal headsets and corded devices accessed from, or used at, a passenger seat location.
(1) This document applies to all TCCA employees and to individuals and organizations. This information is also available to aviation industry for information purposes.

3.1 Personal Headsets
(1) In 1988, the Canadian Aviation Safety Board (CASB), a predecessor of the TSB, issued an Aviation Safety Advisory with respect to the use of personal headsets by passengers.
(2) The TSB advised that a safety deficiency exists if passengers are unable to hear safety announcements over the public address system.
(3) Headsets available from the operator on board the aircraft are often plugged into the aircraft IFE. These systems are equipped with an override feature which gives priority to the public address announcements, allowing safety announcements to be heard by persons using the headsets. In contrast, it is probable that passengers using personal audio headsets connected to a personal device will not hear announcements made over the public address.
(4) The TSB also advised that some advanced technology headsets are capable of excluding up to 85% of ambient noise. Not only are passengers using these types of headsets on board aircraft oblivious to announcements or instructions, but passengers walking to or from an aircraft could be unaware of dangers on an apron.
(5) Most modern headsets and aircraft IFE systems are compatible so that a passenger may bring their own headsets on board an aircraft for personal use.
3.2 Protective Hearing Devices Worn for Medical Reasons or Protective Purposes
(1) Passengers with sensitivity to noise or who have hearing disorders such as hyperacusis may be required to wear protective hearing devices to mitigate discomfort or pain.
(2) This condition causes hypersensitivity to ordinary levels of sound, accompanied by extreme discomfort and pain, but generally does not impair the ability to hear, even while wearing protective hearing devices. These devices may be ear plugs, headsets (without any cables or electronic circuitry), ear caps and/or ear molds.
3.3 Corded Electrical Devices
(1) The increase in the installation and the ability to use corded electrical devices in the passenger compartment has led to requests from CASIs and operators for guidance related to the implementation of operational procedures associated with the use of this type of equipment. These devices are generally intended to provide access to a PED or the aircraft IFE system.
(2) Corded electrical devices are those that are generally attached to the aircraft passenger seat or attached to a bulkhead with a power or signal cord and may include control units for IFE systems and other plug-in devices.
(3) The intent of providing the guidance located in Appendix A is to enable operators to implement operational procedures that will allow passengers to receive and comply with crew member instructions and to minimize the distractions associated with IFE systems during critical phases of flight, thereby increasing a passenger’s situational awareness.
(4) The guidance located in Appendix A will also enable operators to establish procedures that will minimize the risk during critical phases of flight associated with corded devices that may pose a tripping or entrapment hazard.
