The attendants who are responsible for ensuring that any and all required safety and security measures are implemented on board any aircraft performing passenger transportation, and for passengers' comfort, are defined as "cabin crew members" or "cabin attendants". 

Cabin Crew Members, serving at the cabin compartment of the aircraft in order to ensure that flights are operated safely, securely and comfortably, refer to the persons who satisfy the requirements prescribed under the relevant regulations promulgated by the Directorate General of Civil Aviation, and who have completed their trainings successfully, and who, thereby, become entitled to obtain a "Cabin Crew Member Certificate".

Cabin Crew Members have certain duties and responsibilities on board the aircraft. The most significant yet the most unnoticeable of those is to ensure passengers' safety.  This primary responsibility requires that cabin crew members receive a special training on constant basis.  Such training includes theoretical knowledge, as well as developing self-confidence and building this sense of self-confidence and authority the person needs while performing her/his duties. The secondary yet the most noticeable duty of cabin crew members is to meet passengers' needs and to leave a positive impression for the airline for which they work. 

All processes concerning cabin crew members are required to be documented in company manuals or internal procedures of companies approved by the Directorate General of Civil Aviation, as is the case with all Civil Aviation activities:

• Interview and recruitment process
• Training process
• Operation process

Cabin crew members are responsible for the area from the cockpit door to the section called as "aft galley", available at the very aft section of the cabin.  Cabin crew members do not assume any duties and responsibilities inside the cockpit or on the exterior of the aircraft.

In general terms, there are two doors available on the right and left side of the aircraft, for which each cabin crew member is primarily responsible. The scope of such responsibility covers both regular operational conditions and emergency conditions. Under regular operational conditions, opening and closing of such doors by means of the methods provided in the operational manuals of the companies and under emergency conditions, opening of such doors by means of the methods provided in the operation manuals of the companies, and if the external conditions are unsafe, then keeping of such doors closed are covered by the scope of such responsibility.

The duties of cabin crew members regarding service vary depending on the companies. Service may be summarized as offering the products and supplies, deemed appropriate by the airline company, to passengers in accordance with the course and order determined by the respective company upon loading thereof on board the aircraft. Sales of duty-free products in any international flights is considered under the scope thereof.

The trainings regarding the consideration matters and principles in servicing are delivered by the company.
The duties of cabin crew members regarding safety and security may be specified under two main headings:

• Conducting observations and establishing communications in order to prevent occurrence of any cases that may jeopardize safety and security (For example; fire inside the cabin / observation of the cabin / lavatories within regular periods to prevent smoke generation)
• Implementation of emergency procedures in the fastest way with the least casualties possible in order to ensure passengers' safety and security in case of emergencies occurred in spite of all measures taken (For example; in case of an emergency, evacuating all passengers and crew members available on board the aircraft within the periods, tested during aircraft certification, upon the instruction given by the Captain Pilot/Commander)

The trainings which cover such matters (initial safety training, recurrent trainings) have been determined in the relevant legislation of the Directorate General of Civil Aviation, and such trainings are documented in the training manuals of each company approved by the Directorate General of Civil Aviation.
