Wolfram|Alpha: Computational Knowledge Engine Equations - Air Density and Density Altitude updated: Dec 2, 2012 copyright 1998 - 2012 Richard Shelquist Density Altitude On-Line Calculators: For your convenience, the following density altitude calculators are available for use on this web site: - with dew point - using relative humidity What is density altitude? Density altitude is defined as the altitude at which the density of the International Standard Atmosphere (ISA) is the same as the density of the air being evaluated. So, the basic idea of calculating density altitude is to calculate the actual density of the air, and then find the altitude at which that same air density occurs in the International Standard Atmosphere. In the following paragraphs, we'll go step by step through the process of calculating the actual density of the air, and then determining the corresponding density altitude. Some different meanings of the word "altitude": As odd as it may seem, an aircraft altimeter does not actually know anything about altitude, it only measures pressure. Units: (4a) (4b) (12)

Wikiversity AppCode: Objective-C IDE done right Advanced Coding Assistance Code Completion AppCode offers two kinds of code completion: basic as-you-type completion and more advanced "SmartType" completion for more precise filtering of suggestions. Both completion types support "CamelHumps" and "Middle Matching" – that is, you can either complete any item by entering only its uppercase characters, or start typing any middle part of an item. All completion results are ranged and ordered by relevance considering the caret position and surrounding code. Automatic Import and Imports Optimization When you start using a class that is not yet imported, AppCode will suggest you to add the corresponding import automatically, or even add the import when you complete code. With a number of code changes, some imports may become unused, these will be highlighted in the editor. Parameter Info When you call a method or a function, sometimes you might not remember what parameters you should pass to it, that's where Parameter Info (Ctrl+P) can help you.
