Discuss the purpose and characteristics of the following radios:
a. AN/PRC-90-2 |
The AN/PRC-90-2 is a dual purpose, self-powered, personal survival transceiver, used principally for two-way voice communications between a downed aircrew member and a rescue aircraft. Provisions are included for swept-frequency indicator beacon signals to guide rescue efforts. Designed for the following: Two-way voice communications over a range of 60 nautical miles to aircraft operating at 10,000 feet altitude can be expected. An automatic direction fmder (ADF) range of 50 nautical miles and a range of 80 nautical miles to aircraft operating 10,000 feet can be expected. Batteries have a maximum service life of 36 months from date of manufacture. Provides two fixed operating frequencies: the 243.0 MHz guard channel and the 282.8 MHz alternate channel. Is powered by a +14.0VDC mercury battery. The beacon mode transmits a variable frequency, which sweeps from 1600 to 300 Hz and then returns instantaneously to the 1600 Hz frequency and repeats the cycle. This occurs at a rate of 2 to three times per second.

Describe the capabilities of Night Vision Devices (NVD).
|
The ANVIS (Aviators Night Vision Imaging System) is a helmet-mounted passive binocular that provides the capability for pilots to fly in terrain flight modes at night. The binocular is powered by batteries or batteries and an on-board aircraft power converter. The system amplifies ambient light from sources such as the moon, stars, and skyglow so the viewed scene becomes clearly visible to the operator. A light-emitting diode (LED) indicator on the visor mount comes on or blinks if the battery voltage drops below safe limits. The binocular can be adjusted for the distance between the operator's eyes, vertical distance, tilt, eye relief, diopter setting and focus. In addition, the binocular may be flipped up and stored away from the eyes in an emergency. HC-5 currently uses ANVIS-9 devices.

State the conditions that require the use of anti-exposure suits.
|
The outside air temperature (OAT) is 32F.
If the water temperature is between 50F and 60F, the commanding officer of the unit concerned must determine whether anti-exposure suits are necessary based on SAR factors as follows: Assess maximum probable rescue time. This is a function of mission distance, SAR equipment, and SAR location. Determine the lowest water temperature in the mission area during the time period of flight. When water temperature is below 60F and anti-exposure suits are not required, flight equipment ensemble shall include anti-exposure and Aramid undergarments. Wearing double layers of these undergarments can significantly improve anti-exposure performance. Final determination, with regard to actual wearing of anti-exposure suits, shall be made by the CO or officer in charge (OIC) of the unit concerned. It will be based on all pertinent factors (class aircraft, type and duration of assigned mission, ambient cockpit temperatures, suit ventilation features, combat versus non-combat environment, availability of SAR facilities). |
