Pilot's Guide to Ground Icing   (below are some scraps from the course)

Who should take this course?



Every pilot who could encounter ground icing - whether their aircraft needs to be cleaned or protected from frozen contamination.

What is covered in this course?


The problems caused by ground icing


When you are likely to encounter ground icing


The basics about aircraft de/anti-icing fluids


How to de-ice and anti-ice your aircraft


How long will it take?


That depends on you. This course is designed to let you determine what you need to know given the type of flying that you do. You can spend as litle as 60 minutes going through the highlights, but you can take much longer (2-3 hours) if you explore all related information and interactive features.

If the Airspeed Indicator reads ZERO during the takeoff roll, the PITOT tube is BLOCKED. If you do not REJECT the takeoff, but continue to climb-out, the Airspeed Indicator will appear to function shortly after takeoff, but will give you misleading information. If the STATIC ports are not blocked, the Indicated Airspeed will INCREASE with altitude, not AIRSPEED. As the airplane climbs, the Indicated Airspeed eventually exceed the actual airspeed.

Do not be tricked into increasing the pitch attitude and/or reducing thrust - these could cause a perfectly flying airplane to stall.
