1.12. Communication

  1. General — To foster crew coordination and to avoid misidentification and misinformation in dealing with outside agencies (such as ATC), the crew must communicate effectively. To improve the likelihood that information is passed correctly or that a deviation from the desirable is detected, much of the communication that goes on must be standardized in content and phraseology. Specific direction as to the exact wording to be used and related actions, is located throughout the SOPs. The information on communication that is contained in this section does not fit into other sections or is sufficiently broad in application that it is more appropriate to place it here, in a general area.
  2. Intercom Usage [Specify when the intercom is to be used for your type of aircraft and operation. For some aircraft it may be appropriate to communicate using the intercom only during some abnormal procedures. For others, the ambient noise level may be such that the pilots are only able to communicate using the intercom. In order to avoid confusion specify the usage.]
  3. Public Address System [If your aircraft is equipped with a Public Address (PA) System, specify the occasions that the flight crew and other crew are to use it. Obviously, it is not possible to specify all situations. However, some minimum communications requirements should be specified.]
  4. Radio Procedures - Crew Duties — For normal operations both VHF radios should be monitored by all flight crew members. During normal operations the PNF is to make any radio transmissions. During abnormal operations, in the absence of the PNF, when the PNF is engaged in other duties, or should the Captain deem it appropriate, the PF will make any required radio transmission. Which agency is being addressed on each radio shall be made clear to each flight crew member. For example if No. 1 VHF was previously used for communication with Ground Control and the PNF is now using No. 2 VHF to communicate with Tower, that change shall be brought to the attention of the remaining flight crew members.
  5. Radio Procedures - Call Sign — In any transmission to ATC or non-company station the flight crew shall use the full company call sign and flight number. The following is an example of acceptable transmission:
    1. "Winnipeg Centre, Transport One Five Niner [insert company call sign and flight number], level at 3000."
    2. When using the aircraft registration as the call sign, the procedures described in the AIP shall be followed.
  6. Aircraft Internal Communication — Any operational communication whether on the intercom or normal voice shall be acknowledged by the recipient. Although it is not possible to specify all appropriate responses, the following list covers the bulk of situations:
    1. "Check" is used to acknowledge situational information. For example should the PNF advise that the aircraft has descended to within 100 ft of the desired IAP MDA. The appropriate response from the PF would be a simple acknowledgement of "Check". "Check" should be the most frequently used form of acknowledgement.
    2. "Roger" is used where it is advantageous to indicate understanding as part of the acknowledgement.
  7. Standard Phraseology — The following standard phraseology should be used for communications during aircraft operations.
    1. Altimeter Setting — When saying an altimeter setting, the decimal is omitted but all of the digits are included and the unit of measure is included, eg., 29.89 In Hg is read as "two niner eight niner inches."
    2. Crew Duty Stations — When referring to matters that pertain specifically to the seat occupied by a flight crew member the terms used shall be those described in the "Definitions" section of this chapter, eg., "Two niner eight niner inches set pilot".
    3. Command — When referring to matters that pertain specifically to command of the aircraft, the terms used shall be those described in the "Definitions" section of this chapter regardless of the seat occupied. Specifically, the terms "Captain or First Officer" shall be used.

    [For the following subsection "Conversation on the Flight Deck" insert the particulars of your company policy or modify the following to suit your type of aircraft.]

  8. Conversation on the Flight Deck and Non-operational Radio Transmissions — During the following periods, no conversation is permitted other than that required for assigned work or for the operation of the aircraft. During the same periods no non-operational radio transmissions are permitted.
    1. From engine start to top of climb or 10000 ASL/FL100, whichever occurs first;
    2. During descent, from 10000 ASL/FL100, or top of descent, whichever occurs last; until the aircraft has stopped at the completion of the flight;
    3. During the handling of any abnormal situation.

    [For the following subsection "Radio Transmissions to Company Organizations" insert the particulars of your company policy or modify the following to suit your type of aircraft.]

  9. Radio Transmissions to Company Organizations — No transmissions to company organizations are permitted during the following periods:
    1. From taxi on to any active runway or take-off/landing area until the completion of the after take-off check;
    2. From the beginning of the before landing check to until clear of any active runway or take-off/landing area;
    3. During an abnormal or emergency situation except as required to deal with that situation.
  10. Transmissions to company organizations are to be made as follows:
    1. [insert radio communications that are required to be made to company organizations].
