Accurate weather information and prediction is essential. Not all deicing equipment does as good a job at deicing, and unfortunately icibg FAA has not required manufacturers to deal with the issue, nor require commercial aviation companies to invest in retrofitted deicing equipment. Icing conditions are a critical a safety issue which can lead to a major disaster quickly. For example, ice can cause loss of altitude, wing drop stalls, and even engine failures.

The wing will ordinarily stall at a lower angle of attack, and thus a higher airspeed when contaminated with ice.

Airframe Icing – A Pilots Worst Enemy!! – AviationKnowledge

However it can be especially dangerous ao;a formed on the leading edges of the wing, tail-planes or over the air intakes. Ice buildup can transform the shape of the aircraft. With proper training, an pilot can enter icing conditions and maintain lift by increasing speed and changing altitude and angle of flight. Some say that it adds to the overall weight of the aircraft which means that more power is required to overcome the increased weight.

Even small amounts of ice will have an effect, and if the ice is rough, it can be a large effect. Also, the outer part of ickng wing, which is ordinarily thinner and thus a better collector of ice, may stall first rather than last.

The aircraft flew through cloud Instrument Meteorological Conditions. Something does not work as expected?

Airframe icing can also build up on the propeller, windscreen, aerials and air intakes. Thus an increase in approach speed is advisable if ice remains on icong wings. This is not only limited to normally aspirated engines, but can also apply to turbo fans. Not only can airframe icing cause loss of altitude or aircraft speed, but it can also cause the loss of life if not reacted to properly.

Remember that this can cause the inexperienced pilot to raise the nose when trying to stop the sink which can lead to a fully developed stall situation!!!

The lesson will not go so far as to talk about the various deicing or anti-icing systems available in the modern era, but will describe what airframe icing is, what it can do to your aircraft, how it is encountered, what you can do to avoid it and finally how to deal with it if you are unfortunate enough to have accumulated it on your aircraft.

An inexperienced pilot may find the essential navigating commands in icing conditions as counter-intuitive, which is why training is so important. Aircraft tail stall video embedded from You Tube on 28 September Engine failure Ice can cause engine failure in severe conditions and prolonged exposure. Icing will only occur however, in certain temperatures and conditions.

If to much ice is allowed iicing build up on your airframe surfaces during flight it can have absolutely catastrophic consequences.

I will explain these three serious consequences one by one. Aircraft animation – Airframe icing video embedded from You Tube on 28 September Find out what you can do. Xopa characteristics of an aircraft with ice-contaminated wings will be degraded, and serious roll control problems are not unusual. This has major ramifications for air safety!

Ice forms when supercooled droplets of water are suspended in air. Edit History Tags Source. Stalls… The wing will ordinarily stall at a lower angle of attack, and thus a higher airspeed when contaminated with ice.

AOPA Pamphlet Offers Advice on How to Escape Icing Conditions

If you want to discuss contents of this page – this is the easiest way to do it. The FAA is patently ignoring their scientific findings and recommendations due to industry pressure. Refer to the link below for a more in-depth explanation as to how this can occur. A common mistaken belief icihg that airframe icing only accumulates on the leading edges of the wing and tailplane.

Aircraft animation – Airframe ickng video embedded from You Tube on 28 September You will notice three things in this video. They attach themselves to the aircraft when they make contact in circumstances such as flight through cloud. The cause is due aopq the following factors:. This is true, however not the main problem with airframe icing.
