Inputting VIP VRP date in the WDP.
-
Hello Forum
Is there a video or thread showing how to actually input VIP/VRP data into the WDP?
I’ve read the manuals, both BMS and Falcas’s WDP, but it’s still a little unclear to me.
Thanks,
Bayonet.

Hey Bayonet. I typed the following into google and found about ten or more videos.
BMS, VIP VRP video
I’m sure one will help.

Not seeing any videos (at least by thumbnail) on the WDP data entry side of things so I’ll take a swing at it.
Taking a realistic approach a campaign OCA strike was selected. Pop up is not available initially because the IP and strike waypoints are roughly 20,000’ and the option is blocked. The heights are edited in the DTC section to 1,000’ each and the pop up section is unlocked. VRP is used as the steerpoint is the target and low drag is selected for Mk-84s. If VIP reference is selected WDP will give data for the IP steerpoint number such that the target location is the target (next generally) steerpoint. If it’s required to align the INS at the (V)IP perhaps this is a better method but probably never used in BMS.
First choice is the type 1 or 2 pop up. Type 1 is a two-turn profile starting on an axis toward the target, turns away at the PUP and then back in at the apex. Type 2 is a straight line flight from VRP to PUP to apex. Type 2 is chosen this time for its simplicity. A type one approach might make the air defense’s job harder.
Input Panel
Ingress Alt.: A 500’ height is chosen as the threat is not particularly great. The ingress height determines the placement of the pre-maneuver symbols and slightly affects the geometry of the attack. Remember this is height relative to the steerpoint elevation.Dive Angle: Self-explanitory, should be set appropriate to the weapon (Maverick, high drag, low drag) and physically possible. Check the Munition, ballistics section for time of flight for fuze arming. 30 degrees is chosen as a moderate diving angle for Mk-84s providing barely suffient time of flight for fuze arming.
Speed: Unsure if this maneuver start or release speed but 450 KCAS seems reasonable for both. Higher speeds scales up the geometric size of the attack. It should be as fast as the airplane will allow considering stores limitations.
Release Height: According to the ballistics section a height of 2,000’ should be sufficient. More height requires more exposure and a larger attack geometry.
Tracking Time: More time is easier but more exposure. A setting of 3 seconds will require a well-skilled pilot.
Pulling Gs: This should be appropriate for the airplane performance and any limitations. Excessive pulling will bleed airspeed but will shrink the pattern. 4G is selected here as reasonable. This applies to the pull up and the apex turn.
Turn to Target: Right was chosen in this case due to the nature of the pre and post target waypoints as well as the terrain. Coming out of the sun for MANPAD defense might be a consideration.
Attack Heading: This was adjusted until the VRP symbol was placed on the IP-to-TARGET line. This way the flight could be made directly from IP toward target turning away at the VRP toward the PUP.
VRP to PUP distance: This distance may be adjusted based on threat radius (turning away sooner), reducing the turn away angle (longer is less turn), acceleration requirements (distance required to accelerate to attack speed), or simply timing and pace. 3nm was chosen which should take 24 seconds at 450 G/S.
OA2 AOP: OA2 normally is vertically below the apex marker OA1. Optionally it can be placed at the AOP for the dive section. Normal placement aids in pointing at the apex marker which may be hard to find directly. In this case finding the marker directly below it first and then pulling up may be easier. The OA2 mark at AOP aids the dive delivery.

thank you both, I have seen all the videos of VRP, VIP etc.
It was input into the WDP I was looking for.
Thanks Frederf for the comprehensive reply.
