The initial GPS radiosonde is the Lockheed Martin Sippican MkIIA. Each radiosonde manufacturer has prepared step-by-step instructions for preparing their radiosondes for the observation. The observers should follow these instructions and those provided in either Appendix N for the GPS radiosonde or instructions supplied in the shipping box for. Frangibility Research Octo Task 3 - Test Setup Development • Testing Setup being developed by MIRA of the UK working with SES. • Testing to be conducted on a fixed-rail test track meters in length and 4 meters in width. • Rail-Guided Trolley (3, kg mass) will be accelerated to kph utilizing a computer.   In the current study, a radiosonde humidity sensor was located inside the test chamber for the calibration in terms of relative humidity, as shown in the inset of figure 1(b). The temperature of the test chamber varied from 20 °C to −70 °C, and the pressure varied from kPa to 5 kPa during the calibration of the by: 3. The radiosonde instrumentation is contained within a small white box attached to a weather balloon that is filled with either hydrogen or helium (Fig. ).Fig. shows a close-up photo of typical radiosonde instrumentation. Similar to its ASOS counterpart (see Chapter 2), the temperature sensor uses the principle of electrical resistance to measure temperature changes with altitude.

Key Words Fire Safety, Aircraft interior materials, Flammability Distribution Statement This document is available to the public through the National Technical Information Service (NTIS) Springfield, Virginia. Frangibility can be incorporated into the support structure by means of a mechanism that slips (e.g. slip-bases), breaks, or folds away on impact and removes the structural integrity of the support. A frangible mechanism can be designed to withstand high wind loads but remain very sensitive to impact loads.   In the test, a deflection at N ( m) was compared with , , , m obtained in the simulations (from 10% to 35% less than the nominal value). Therefore, from the frangibility perspective the performance of the simulated column is conservative.

In order to develop international regulation for the frangibility of equipment or installations at airports, required for air navigation purposes (e.g., approach lighting towers, meteorological equipment, radio navigational aids) and their support structures, ICAO initiated the "Frangible Aids Study Group" in , with the task to define.
