  1. AIRCRAFT GROUND DEICING/ANTI-ICING Jeanne Cook - Bankair

  2. 135.227 (b) No certificate holder may authorize an airplane to take off and no pilot may take off an airplane any time conditions are such that frost, ice, or snow may reasonably be expected to adhere to the airplane unless the pilot has completed all applicable training as required by §135.341 and unless one of the following requirements is met:

  3. A pre-takeoff contamination check, that has been established by the certificate holder and approved by the Administrator for the specific airplane type, has been completed within 5 minutes prior to beginning takeoff. A pre-takeoff contamination check is a check to make sure the wings and control surfaces are free of frost, ice, or snow.

  4. (2) The certificate holder has an approved alternative procedure and under that procedure the airplane is determined to be free of frost, ice, or snow.

  5. (3) The certificate holder has an approved deicing/anti-icing program that complies with §121.629(c) of this chapter and the takeoff complies with that program.

  6. PRECONTAMINATION CHECK ORALTERNATE PROCEDURE

  7. 5 MINUTES

  8. FAA TYPE III Holdover Time Guideline • Table 3.  FAA Guidelines for Holdover Times SAE Type III Fluid Mixture as a Function of Weather Conditions and OUTSIDE AIR TEMPERATURE.  • CAUTION:  THIS TABLE IS FOR DEPARTURE PLANNING ONLY AND SHOULD BE USED IN CONJUNCTION WITH PRETAKEOFFCHECK PROCEDURES.

  9. THE RESPONSIBILITY FOR THE APPLICATION OF THESE DATA REMAINS WITH THE USER. *Use light freezing rain holdover times if positive identification of freezing drizzle is not possible   **This column is for use at temperatures above 0˚C (32˚ F) only   + Snow pellets, ice pellets, heavy snow, moderate and heavy freezing rain, and hail.

  10. CAUTIONS: • THE TIME OF PROTECTION WILL BE SHORTENED IN HEAVY WEATHER CONDITIONS.  HEAVY PRECIPITATION RATES OR HIGH MOISTURE CONTENT, HIGH WIND VELOCITY, OR JET BLAST WILL REDUCE HOLDOVER TIME BELOW THE LOWEST TIME STATED IN THE RANGE.  HOLDOVER TIME MAY BE REDUCED WHEN AIRCRAFT SKIN TEMPERATURE IS LOWER THAN OAT. • SAE TYPE III FLUID USED DURING GROUND DEICING/ANTI-ICING IS NOT INTENDED FOR - AND DOES NOT PROVIDE - PROTECTION DURING FLIGHT. 

  11. Looking at the Active Frost or the Freezing Fog, you can easily determine the time benefit of being able to use a HOT

  12. Our goal is to have an alternate procedure that allows the PIC to be the person trained in deicing an aircraft

  13. RACCA has been working with the FAA for two years regarding this issue. The FAA is working closely with us in looking at sample programs. The FAA states that we should have an approved alternate program by this winter season.
