(1) Before commencing deicing/anti-icing operations, ground personnel and the flightcrew should review the following (as applicable):
Page 8 Par 6
12/20/04 AC 120-60B
(a) Deicing/anti-icing prior to crew arrival.
(b) Gate or remote deicing/anti-icing procedures.
(c) Aircraft-specific procedures.
(d) Communications between ground personnel and the flightcrew.
(2) Just before commencing the application of deicing/anti-icing fluid, ground personnel should confirm with the flightcrew that the aircraft is properly configured for deicing, as follows:
Example: “Captain, is your aircraft ready for deicing/anti-icing?”
(3) Upon completion of deicing/anti-icing, provide the flightcrew with the following elements:
A: Fluid type (e.g., Type I, Type II, Type III or Type IV) Fluid product name optional for each type of fluid if fluid meets product on-wing viscosity requirements.
B: Fluid/water mix ratio by volume of Types II, III, and IV. Reporting the concentration of Type I fluid is not required..
C: Specify, in local time (hours and minutes) the beginning of the final fluid application (e.g. 1330).
D: Post application check accomplished. Specify date (day, written month, year).
NOTE: Element D is required for recordkeeping, optional for crew notification.
NOTE: Transmission of elements A-C to the flightcrew confirms that a post deicing/anti-icing check was completed and the aircraft is clean.
Examples of the ground/flightcrew communication sequence for the one and two-step processes follow:
One Step Process with Type I or other approved deicing fluid: “Captain, I am your designated deicer. Your aircraft has been deiced with Type I fluid. Your fluid application began at 1430.”
Two Step Process with Types II, III, or IV: Captain, I am your designated deicer. Your aircraft has been deiced with Type I fluid and anti-iced with Type IV. An anti-ice fluid mixture of 75 was used. Your anti-ice fluid application began at 1645.
g. Initial/Recurrent Ground Training and Qualification. Per section 121.629(c)(2), only exclusively trained and qualified personnel may carry out deicing/anti-icing procedures.
(1) Each certificate holder’s approved program must consist of the following:
Par 6 Page 9
AC 120-60B 12/20/04
(a) Certificate holders must conduct initial and annual recurrent training for flightcrews, dispatchers, and ground personnel and should ensure that all such crews obtain and retain a thorough knowledge of aircraft ground deicing/anti-icing policies and procedures, including required procedures and lessons learned.
(b) Flightcrew, dispatcher, and ground personnel training programs must include a detailed description of initial and annual recurrent ground training and qualification concerning the specific requirements of the program and the duties, responsibilities, and functions detailed in the program.
(c) Flightcrew, dispatcher, and ground personnel training programs should have a Quality Assurance Program to monitor and maintain a high level of competence. An ongoing review plan is advisable to evaluate the effectiveness of the deicing/anti-icing training received.
(d) The program should have a tracking system that records all required personnel have been satisfactorily trained. Certificate holders shall maintain records of personnel training and qualification (see Appendix 2) for proof of qualification.
(e) Personnel must be able to adequately read, speak, and understand English in order to follow written and oral procedures applicable to the deicing/anti-icing program.
(f) When the anti-icing fluids are used, the flightcrews should be made aware of any unusual flying qualities, such as the need for additional takeoff rotation stick-force.
(2) Certificate holders should train and qualify flightcrew, dispatcher, and ground personnel on at least the following subjects, identified as Flightcrew (F), Dispatcher (D), or Ground Personnel (G):
(a) Effects of Frozen Contaminants on Aircraft Surfaces. Provide an understanding of the critical effect the presence of minute amounts of frost, ice, or snow has on flight surfaces. This discussion should include, but is not limited to:
1 Loss of lift.
2 Increased drag and weight.
3 Decreased control.
4 Tendency for rapid pitch-up and roll-off during rotation (F/D only).
5 Stall occurs at lower-than-normal angle of attack (F/D only).
6 Buffet or stall occurs before activation of stall warning (F/D only).
7 Aircraft specific areas:
Page 10 Par 6

(aa) Engine foreign object damage potential.
(bb) Ram air intakes.
(cc) Instrument pickup points.
(dd) Leading edge device (LED) aircraft (aircraft that have slats or leading edge flaps) and non-LED aircraft.
(ee) Airworthiness Directives/Specific inspections.
(ff) Winglets.
(b) Aircraft Ground Icing Conditions. Describe conditions that cause implementation of deicing/anti-icing procedures (F/D/G).
