military chart symbols
Hi
Can anyone please explain the following 3 symbols on the MOD charts?
1) Purple(ish) radiating lines, rather like an 8-spoked bicycle wheel sometimes with an alphanumeric designation or asterisked number (height?)
2) "Inverted blue pac man" on the half-mil chart with a number after it in the format "x/xxx" or on the quarter mil chart either shaded or with a "W" next to it.
3) The red diamonds, sometimes in a shaded ring.
I trust you won't think it a risk to security to explain these symbols. I gave back my ID card a long time ago...
Thanks in advance.

I"ve been using civ charts for a while now, so others may need to correct my reply but, from memory:
purplish radiating lines - JTIDS avoidance 'area'.
Inverted pacman - parascending.
Red diamond - industrial avoid
As I said, it's been a while, so I may be wrong.

Sounds bad to me...
The purple shape you describe sounds more like a High Intensity Radio Transmission Area (HIRTA), the numbers and letters beside it being the frequency band and the worst case avoidance height. A JTIDS avoid is more like a wheel rim with cog teeth all around it.
The upside down pacman is a hangliding site, the W signifying that a winch system may be used (up to 3000' at normal glider sites) and the number represents the LFA and site number.
The diamond could either be an industrial avoid as mentioned above but could equally be a nature reserve.

Get yourself a MilFlip account and download the LFC legend
They are:
HIRTA
Hang-glider site
Industrial/Nature Reserve

MilFlips...
Word of advise when googling MilFlips. Don't do it in front of the wife.
So, explain the red diamonds...
During our low flying training on the G-nat, we all dutifully avoided some LFA avoidance, which was a mink farm in Viet Taff land. However, the druid who owned the place kept ringing up and complaining angrily.
Eventually someone decided to check. Yes, it had been mis-plotted on the official LFC..... So by carefully trying to avoid it, we'd actually been wiring the place - which apparently causes the nasty little $ods to kill each other during their $hagging season...
