Air-to-Air Radar by Howdog Radar for Hornet 3.0 seemed nice at first, but gradually I begain using TWS and ACM modes only. I would rarely get a lock with the other modes. (RWS and VS). With the new [F/A-18 Korea v1.0] manual in hand I did some math. I knew before I read this manual that 140deg 6 bar search would take a while, but i never knew it took 39 seconds to complete! I always gave up on the RWS and VS modes too quickly, plus I was not using the 40 and 60 degree setings much. Here are my findings based on the fact that the radar scans azimuth at a fixed rate of 21.5deg per sec. and scans one bar at a time [F/A-18 Korea manual, page 142 ] Hopefully this info will help us become more effective with our radars...    RWS and VS          140deg.  6bars=39sec.  4bars=26sec.  2bars=13sec.  1bar=7sec.  80deg.  6bars=22sec.  4bars=15sec.  2bars=7sec.  1bar=4sec.  40deg.  6bars=11sec.  4bars=7sec.  2bars=4sec.  1bar=2sec.  20deg.  6bars=6sec.  4bars=4sec.  2bars=2sec.  1bar=1sec.  TWS  A complete scan always takes between 6 and 7 sec on TWS. (no matter what the azimuth and elevation.)   Note on scan time: These times are rounded to the nearest second and are for a COMPLETE scan of the radar volume specified. This means you may get a radar contact BEFORE the complete scan finishes. In fact, on AVERAGE you should get your contact in half the scan time. Note on VS mode: With VS you can toggle maximum closing velocity by using the tab key. Note about hi-fidelity radar option: Looking at a chart of radar scan times for the selected volume of air you want to scan while you are flying seems a little impractical. Memorizing a chart is also impractical. so i just cams up with this method. For RWS and VS: Look at the degree (azimuth) setting. Chop off the zero, halve the number, multiply by the number of bars (elevation). This will give you a good aproximation of the time. It is really not as bad as it sounds. Eample: 60 deg, 4 bar scan. Take the 60 and chop off the 0. (leaves 6). Halve the 6 (leaves 3). Multiply the 3 by 4 (since 4 is the number of bars used in this scan). You get 12 seconds (one second off from the chart (not bad). Don't bother calculating TWS. It is always 6-7 secs. There is still a lot to learn about the APG-65's radar features, and also a lot to be field tested. If anyone finds any error in this information, please let me know. I still need to explore STT and ACM radar modes, although these are a little more self explanatory.
