PVI 800 co-ordinates?

[Raven_Morpheus]

Hello

 

Just a quick question, I'm wondering how are the waypoint co-ordinates expressed on the Ka-50 PVI-800?

 

For example, in a mission I have a 1st waypoint and the PVI displays the following for it -

 

1st line reads 42'09'7 1

2nd line read 042'23'7

 

I'm assuming the 1 means it's waypoint 1. But what about the rest, are they longitude, latitude expressed in minutes, if so what's the 7 on each line supposed to mean and why are there 2 lines that differ?

 

TIA

Uhm, the manual does not cover the topics PVI, latitude and longitude with decimal minutes instead of seconds?

the PVI uses lat/long decimal, The last two digits are averaged. The 1 represents which waypoint/point

From an old post:

So if you have the coords 44'45.46 in the ABRIS, you would type 044458 into the PVI

 

Why did the 46 seconds in the coords turn to an 8? Let's look at the numbers (0)-(44)-(45)-( 8 )

0

= Prefix to indentify the coord as positive

(not a number translated form the ABRIS coords)

44

= Degrees

45

= Minutes

8

= Which is

46

seconds, divided by 60

(which is 0.76)

, rounded to the nearest tenth

( 76 rounds up to

8

)

Rather than using the ERBL, I like to insert a new waypoint or map point into the ABRIS as a reference. At first this took much longer than doing a quick ERBL or INFO, but now I'm so used to it that it takes no time. Plus you get perm intel on the map point like coords, time and bearing to target, elevation, range, etc. Take note that if you create a map point in the ABRIS, then translate it to a PVI NAV/TGT, when you select that NAV/TGT and uncage your shkval (turn on TV) your tracking cursor on your targeting system automatically moves to that NAV/TGT.

 

A practical use of this would be something I experienced yesterday. There was a SAM site equipped with a radar truck, so he was able to track, target, and eliminate me very quickly. I was able to identify the origin of the missile trail coming from a bend in the road before I ejected. Once I got in a new bird I pulled up my ABRIS and found that bend in the road on the map. I plotted course waypoints (manual p231) into the ABRIS that would take me 5km from the SAM site, but behind a mountain. I marked the SAM site on the ABRIS as an INFO type map point named 'SAM' (man p253). I saved the ABRIS info and made it active. I then pulled up the info point named 'SAM' and translated the coords into the PVI (man p319). I followed my ABRIS waypoints to the ingress area behind the mountain, initiated a hover, activated NAV/TGT 2, uncaged my Shkval, and as soon as I crested the mountain I was viewing the SAM site zoomed in on my targeting system. I was able to get a lock and release within seconds.

Corrected lat/lon to minutes.. thanks ajax

I don't think that's right, StrongHarm. To enter 44 deg 45.46 min into the PVI-800 you enter 44455 (rounding 45.46 to 45.5). Unless you really meant 44 deg 45 min 46 sec, in which case you're right.

1st Line is latitude: 42097 = 42 deg 09.7 minutes (the 1 is the WP or TGT PT.)

2nd Line is longitude: 042237 = 042 deg 23.7 min

 

Latitude requires one less digit because latitude only ranges between +/- 0 to 90 deg. In contrast, longitude can range between +/- 0 to 180 deg.

The simplest way is to just change coordinates in ABRIS to decimal. Then any coordinates you get, will be easily entered into the PVI.

Reaper and Strongarm are both righht. One need to work in decimal. This is quite a challenge when co ordinating with A10C which are working in degrees, minutes, seconds.
