ANALYSIS THE RUNABOUT INFERENCE-TICKET By A. N. PRIOR T is sometimes alleged that there are inferences whose validity arises solely from the meanings of certain expressions occurring in them. The precise technicalities employed are not important, but let us say that such inferences, if any such there be, are analytically valid. Loop Heat pipe Anti Icing System Development Program Summary This paper describes a NASA sponsored Phase II SBIR program to develop a passive aircraft anti icing system. The system takes waste heat from the engine or hydraulic system and passively transports this heat to the engine inlet to prevent ice by:
At the conclusion of the research, there was a need to communicate the guidelines and tools to practi-tioners at state and local transporta-tion agencies. This experimental investigation was conducted in an open circuit wind tunnel, capable of speeds up to ft/sec at a Reynolds number of x10s per foot. The test section is approximately feet high, feet wide and feet long. Windows exist on the tunnel top and sides which provide good visibility and aid in obtaining flow Cited by: 6.
To assist air operators in establishing Surface Contamination Training, Transport Canada has made available this training package concerning the adverse effect of critical surface contamination on aircraft performance. This package consists of three video's and this accompanying Training Manual (TP E) plus sample examination questions.

Icing analysis is required to determine the size and location of ice shapes that would occur during the minute hold. Those shapes are compared with icing shapes created during climb, cruise, and descent conditions to determine the most critical icing flight regime for the airplane.
After icing shapes are determined, models of the. The amount of anti-icing liquid applied to the roadway is unlikely to make roads slippery.
However, motorists should always remain at least feet behind a vehicle applying an anti-icing liquid. If applied before a storm, the anti-icing liquid typically dries within 45 minutes, leaving a thin layer of anti-icing product on the road Size: KB. icing are that it: (1) maintains the roads at the best condition possible during winter storms, (2) uses fewer chemicals, therefore it is cost efficient and better for the environment, and (3) it makes subsequent road clearing easier.
Anti-icing can decrease costs by greater than 50% compared to conventional de-icing (p57).

The applicability of CT technology to the study of highway icing and its use in studying an ice adhesion enhancing mechanism referred to as “keying” were investigated. An understanding of the relationships between the texture of a roadway's surface and the adhesion ice and its control may be greatly furthered if experimental investigations.
Anti-Icing Study Completed. To wrap up its 2-year anti-icing test and evaluation project (TE 28), FHWA hosted a symposium on anti-icing technology in October in Estes Park, Colorado. The more than participants represented State and local highway agencies, academia, consultants, suppliers, and manufacturers.

Also, pilots of Caravans equipped for flight into known icing conditions should be required to undergo annual training on ice safety, the NTSB said.
The NTSB based its recommendations on a study of 26 icing-related accidents and incidents involving Caravans between andwhich resulted in at least 36 fatalities.

Below is the uncorrected machine-read text. De/Anti-Icing 4. Deicing is a procedure by which frost, ice, snow or slush (i.e. the frozen contamination) is removed from an aircraft by use of a heated aircraft deicing fluid (ADF), to provide clean surfaces.
Anti-icing is a procedure in which an aircraft anti-icing fluid (AAF) is applied to a surface free of frozen contaminants in order to. Premature deterioration of concrete due to materials-related distresses has been observed with increased frequency in airfield pavements across the United States in the past two decades.
The use of a new breed of deicing chemicals based on alkali-acetates and alkali-formates, starting in the early s, has been suspected to be one of the significant reasons for the increase in Author: David Wayne Wingard.

Best Practices for Road Weather Management The Governor ordered contraflow operations to minimize travel times during reentry.
Traffic and emergency managers quickly developed a contraflow plan to accommodate reentry traffic in reversed westbound lanes. DMS and HAR were deployed to notify travelers of closures and alternate routes.
