What is Known Ice? FAASTeamNORTH DAKOTA
What is Known Ice?_____________ • Concept vs. Regulatory • Regulation • Preflight Briefing • Weather Forecasts • Airman Responsibilities and Considerations
Known Ice… “Known Ice”, involves the situation where ice formation is actually detected or observed.
Known Icing Conditions… …Involve instead circumstances where a reasonable pilot would expect a substantial likelihood of ice formation on the aircraft BASED UPONALLINFORMATION AVAILABLE TO THE PILOT.
Regulations Involved… 14 CFR Part 91 91.9 - Aircraft Limitations 91.13 – Careless or Reckless 91.103 – Familiarization with, weather and flight planning data… 91.527 – Operating in Icing Conditions Part 91 Part 61 44709
Thoughts?! • Documentation: • TCDS • POH/AFM • STC
Thoughts?! Physical Inspection and Condition: • De-Ice/Anti-Ice Equipment Operational • Conditional • OAT • Historical review of Maintenance • Duration (time in clouds) • Alternates and Options
91.13 / Careless or Reckless?_______ • Careless - Not giving sufficient attention or thought to avoiding harm or errors. • Reckless - Without thinking or caring about the consequences of an action: "reckless flying".
…with all available information… QICP AFSS ATC NWS “Pilots own Observations”

Weather data sources:_____________ • Airmets • Winds Aloft Reports and Forecast • Radar Summary Charts • Pilot Reports (PIREPs) • ATIS (Local only reports) • ATC – ask!!! “Hey Center, do you have any reports of icing along my route to…”? • Listen to the radio. (122.0)

Remember:______________________ AIRMETS use VORs for points of measure.
Remember…_____________________ • Ice usually forms when visible moisture is at temperatures between +5°C and -20°C contact the aircraft • More typically…Ice forms at temps between +2°C and -10°C • There is generally more ice in the top 1/3 of the cloud deck than the reminder of the cloud.
Question?____________________(22) What is the lowest ambient temperature at which a super-cooled water droplet can remain in liquid state? A) +20 F B) +10 F C) 0 F D) -40 AC00-6A pp41
Question?___________________(23) If your aircraft is approved for “known icing” conditions, what are its limitations? A) Moderate icing, takeoff, cruise, and landing. B) Moderate icing, climb, cruise, and landing. C) Light icing for takeoff, Moderate icing for climb, cruise, and landing. D) Moderate icing, takeoff, climb, cruise, and landing. 135.227(b)(1), (c)(1) / 91.527
Question?____________________(26) Your clearance is, “CLEARED AS FILED, MAINTAIN 12,000”. You encounter ice pellets from takeoff to 11,500 feet, at which point you fly into freezing rain. What clearance amendment should you request? A) An increase in airspeed. B) A lower altitude. C) Both an increase in airspeed and a higher altitude. D) A higher altitude.
Question?____________________(28) In which meteorological environment is aircraft structural icing most likely to have the highest rate of accumulation? A) Cumulonimbus clouds. B) High humidity and freezing temperatures. C) Heavy wet snow. D) Freezing rain.
Question?____________________(30) The body of a TAF covers a geographical area within… A) 5 statute mile radius of the center of a runway complex. B) 25 statute miles from the center of an airport. C) 10 statute miles of the station originating the TAF. D) 10 statute mile radius of the center of the airport. AC-60 4.47
Finally________: • Never • Ever • Let ATC be the PIC of YOUR Airplane!!
When dealing with ATC____________ • Tell them what you need • Tell them you are picking up ice, the severity, and what it is you want to do. • Tell them that you need “PRIORITY” handling If icing severity or your not comfortable: • DO NOT HESITATE TO DECLARE AN EMERGENCY!! 7700
Get it back on the Ground__________ • Considerations: • Make gentle wide turns • Utilize ATC for Vectors to final • Use an ILS approach if available • Longest runway • Keep your speed up • Leave the flaps where they are, YOU DO NOT NEED THEM!
It is better to slide off the end of the runway at 10kts, than…
Than crashing short of the runway! • Date: 31 October 1994 • Airline: American Eagle, Flight No.: 4184 • Aircraft: ATR-72 • Location: Roselawn, IN • Souls on Board: 68 • Fatalities: 68 • The aircraft crashed while in a holding pattern to land at Chicago's O'Hare Airport. Ice buildup accumulated on the wings faster than the de-icing boots could remove it, and the aircraft entered a spin from which the crew was unable to recover.
