Karten in diesem Stapel (45)
- 1Although not particularly relevant to the military environment, what are the two distinct areas associated with aircraft icing?a
- 2List the three basic conditions which must exist for ice to form on an airframe.a
- 3Define freezing level.a
- 4Calculate the freezing level or altitude given the following: +8°C at 5,000 ft AMSL.a
- 5Under what general conditions would continuous icing conditions usually be found near freezing level?a
- 6Why is icing more likely to occur at almost any level within cumuliform clouds than other types of clouds?a
- 7Large supercooled droplets striking a below-freezing airframe are likely to form what type of ice?a
- 8Describe one situation in which it is possible to have supercooled water droplets form – and at what temperatures can such droplets exist?a
- 9How can supercooled droplets spread out even further on an airframe before fully freezing?a
- 10List the basic characteristics of clear ice when formed on an airframe.a
- 11What dangers are posed by clear ice forming on an airframe?a
- 12Describe the indications available to a pilot that freezing rain may exist at higher altitudes.a
- 13Small supercooled droplets striking a below-freezing airframe are likely to form what type of ice?a
- 14What are the physical characteristics of ice formed under the conditions in question 13 (above)?a
- 15What common range of temperatures is conducive for the formation of rime ice on an airframe?a
- 16Cloudy ice is another name used to describe what type of ice?a
- 17Explain the conditions that must exist for the formation of hoar frost on an airframe.a
- 18Other than to ensure that you have a clear view through a frosted windscreen, what other reasons exist to ensure the removal of frost from an airframe before flight?a
- 19Describe the conditions required during flight for the formation of hoar frost.a
- 20In which family or genera of cloud, and under what range of temperatures, is there a severe risk of airframe icing?a
- 21In which family of cloud, and under what range of temperatures, is there a light risk of airframe icing?a
- 22Describe the conditions under which airframe icing is a risk during flight within stratiform clouds.a
- 23Explain why flight in an aircraft with an airframe temperature below 0°C should be avoided.a
- 24Describe the effect on freezing level of orographic lifting.a
- 25Describe the level of airframe icing to be expected within high-level cloud such as cirrus.a
- 26List the three basic classes of icing that present hazards to an aircraft and the pitot/static system.a
- 27List the possible adverse effects of airframe icing.a
- 28Describe the principal (and almost immediate) hazard posed to helicopters during flight into icing conditions.a
- 29Explain the reasons why it is necessary to turn on anti-icing systems, especially those associated with engine intakes and FOD screens, prior to entering known icing conditions.a
- 30Explain why the decision to activate windscreen anti-icing systems later rather than earlier is so important with helicopter flight in possible icing conditions.a
- 31What possible hazards exist for external weapon systems on helicopters during flight into icing conditions?a
- 32Can radio communications be affected by airframe icing?a
- 33Other than damage to rotors, engine intakes and visibility, what is the main hazard associated with airframe icing on helicopters?a
- 34Explain how very high speed in helicopters is not particularly conducive to the formation of main rotor icing with rotary wing aircraft.a
- 35What part of the rotor system on helicopters is more prone to the formation of icing (during flight into icing conditions)?a
- 36Describe the indications available to the pilot of a rotary wing aircraft of the possible formation of rotor icing.a
- 37What is the common rule-of-thumb that applies to main rotor icing and being able to successfully conduct an autorotation?a
- 38What system of main rotor de-icing is generally available on modern rotary wing aircraft?a
- 39Describe the basic blade de-icing systems available on the Black Hawk helicopter – and what conditions are likely to be observed during its operation?a
- 40What is meant by the term impact icing?a
- 41What is the major hazard associated with respect to turbine intake icing, and how can this be reduced?a
- 42Describe the conditions under which turbine intake icing is likely during taxiing on the ground, particularly at high engine RPM.a
- 43Define catch efficiency.a
- 44Describe why propeller icing can be extremely hazardous to flight.a
- 45What is the difference between anti-icing and de-icing systems?a
