<?xml version="1.0"?> <!-- Improved altimeter instrument. Adds enhancements allowing for calibration. Jan, 2001 by Julian Foad <julianfoad@netscapeonline.co.uk> Julian sez: "provides a modified instrument definition with a knob driving a subscale showing through a cut-out in the face.... I've put two lines in 'altimeter.xml', one to display millibars and another, presently commented out, for inHg; USA pilots might want to uncomment the inHg line instead. At present, my subscale texture map only has marks on it, not numbers, so it can stay the same. Really there should be two different versions of the altimeter, and a USA-registered C172 would be fitted with an altimeter with inHg while and a UK-registered C172 would be fitted with an altimeter with mb on its subscale." _________________________________________________________________ Based on default by David Megginson, david@megginson.com. This is an instrument configuration file for the open-source flight simulator FlightGear (www.flightgear.org). The file is an XML-encoded FlightGear property list defining the instrument's layers and actions. Each instrument is composed of layers stacked on top of each other. A layer may be a texture (with transparent parts to show the layers underneath), text, or a special layer that switches between two others (say, to turn an indicator light on or off). Each layer can move independently in proportion to a property value, and text can be generated from property values as well: all of the layer's movements are defined as transformations. Actions are hotspots on the instrument that will respond to a mouse click. Actions always modify the values of properties, either by adjusting them, toggling them, or swaping them with other properties' values. --> <PropertyList> <name>Altimeter</name> <w-base>128</w-base>
