COCKPIT TO CABIN COMMUNICATIONS Sterile Cockpit Rule


When a flight crew’s attention is diverted from the task of flying, the chance of error increases. Over the years there have been dozens of air carrier accidents that occurred when the crew diverted attention from the task at hand and became occupied with items totally unrelated to flying. Consequently, important things were missed. Things like setting the flaps prior to takeoff, or extending the landing gear before landing. Things like monitoring altitude on an instrument approach, or using engine anti-ice for takeoff during a blinding snow storm. FAR 135.100 was enacted to help curb the number of these accidents. Commonly known as the “sterile cockpit rule,” these regulations specifically prohibit crew member performance of non-essential duties or activities while the aircraft is involved in taxi, takeoff, landing, and all other flight operations conducted below 10,000 feet MSL, except cruise flight.


While the methods used in communicating with the cabin may vary with aircraft equipment and between operations, certain signals and procedures are required.


Seatbelt Advisory Lights


Pilots are advised to use the advisory lights as required. The PIC must ensure the passengers have been notified verbally each time it is necessary to fasten their seatbelts and when smoking is prohibited.


Regulations require the pilot in command to ensure the seatbelt advisory lights are illuminated:


• During taxi, takeoff, approach and landing • When turbulence is expected or encountered • At any time deemed necessary by the PIC


No Smoking Advisory Lights The No Smoking advisory lights will be illuminated: • For all ground operations • Taxi, takeoff, approach and landing • When aircraft, walk-around, or medical O2 is in use • At the discretion of the PIC


Additional Signals Cabin personnel and/or passengers will be notified: • Prior to initiating the takeoff roll


• When cabin service must be suspended due to turbulence


• 10 minutes prior to expected landing • Of any circumstance deemed necessary by the PIC
