RB 75 - NAV or ANF?

[imacken]

The manual - p320 - says the RB 75 should be set to NAV, whereas the Weapon Chart and every tutorial I've seen says it should be ANF.

Confused!

You have to set Master Mode to ANF to turn on the EP13. So ANF.

Not true, setting to UNSAFE in NAV turns on the EP13 as well with same functionality.

There must be a difference.

HERE is one substantive difference between the two modes and how they apply to the RB75.

 

ANF mode allows you to see a target-waypoint marker ** on your HUD, provided the weapon trigger is safe.

In NAV mode, you will not get this target marker.

 

You can fire the weapon in eiher NAV mode, or ANF mode.

The EP13 will turn itself on when you go from "SAFE" to "UNSAFE" in either mode.

Here's how I decide whihc to use:

NAV MODE: I use Nav mode if I do not have a pre-programmed "M"-type attack waypoint. If I'm just navigating visually or only have a "B"-type waypoint then I use NAV mode.

Also, If I already know where the target is and can see it from long range on my approach then I do not need the HUD marker.

 

ANF MODE:

I use ANF mode when I am flying to an unknown location/target and where I want help fromt he HUN in advance in order to line up correctly.

This ia especially helpful when using auto-generated attack waypoints from the kneeboard/cartridge, or when approaching the target IFR or from behind visual cover such as a mountain.

However, as soon as you UNSAFE the trigger, the hud marker will disappear, and you will most likely use the EP13 for fine targetting control at that point.

 

** See this video from 6:55 in order to see the marker as I switch the trigger from unsafe to safe and back in ANF mode.

I stand corrected... Thanks!

Thanks Phil. Good points, but I can't really see any advantage in using NAV at any time.

Only if you think you might forget to switch back to it after weapons release?

But yeah, it doesn't seem to offer specific advantages over ANF for the run in to target as far as I can see.

Essentially why I said what I said - never tried to do it via NAV because I never found a methodology required to deploy the RB75 where I wouldn't have changed to ANF. I prefer having the aiming cue on the HUD to point the nose - but that might also just be because I am the worst at deploying the RB75.

I am the worst at deploying the RB75.

I've found that key-bindings is critical to deploying the RB75 effectively. There's quite a lot of ergonomics involved in getting it smooth and not-cumbersome.

 

I've had to do the following:

(I am right handed)

1. I Assigned the up-down-left-right movement of the EP13 scope to the cursor keys on my keyboard. I move the scope round with my right hand, fingers on the cursors.

2. I have the T0, T2 and T2 options bound to a seperate button box (actually an Elgato streamdeck) that sits on my desk, left of my joystick, kind-of above my left knee. So, whilst looking through the EP13 scope, with my right hand on the cursor keys, my left hand is on the three T0, T1, T2 buttons. As I am lining up a target vehicle/object with the cursor keys, I repeatedly press the T2 button with my left hand until it "fixes" the scope.

3. Once fixed I lean back fromt he scope and prss the fire trigger, which is on my joystick.

 

(in order to line up the EP13 scope, it's almost always necessary to have the aircraft at least on attitude hold. Occasionally I will move the nose around with the stick if the scope is too far off the target, but very small nose movements cause a lot of scope movement especially at longer ranges from the target).

 

As time has gone by I've realised that 1 or 2 RB75s is the max I can expect to get onto most targets. I just run out of time/ room to deploy any more.

For this reason I seldom take more than 2 in my loadout.

Phil, I think it's Tv not T2.

I have a (for me) simpler approach to the RB 75 mapping. I use that recommended in Chuck's guide, and all the buttons/movements are done without even taking any hand off the HOTAS!

EP 13 scope movement on the radar stick, Tv - press in radar stick and T0 and T1 buttons are the buttons left and behind the trim hat.
