Hud Settings & Options

[pauldgardner 2]

Hi,

I am enjoying the superb F-16 and its features, but I am having trouble understanding the HUD viewing funtions/ options.

The manual is good but lack sufficient detail in the HUD area to explain the use of ther various HUD switches, what they are for and when to use them.

I am sure many experienced flight simmers understand all of this but maybe I am not alone in needing some further explanation.

Any chance of some help?

Cheers

Mmmm I see what you mean but at the same time I find it hard to explain what should be used for what and in what occasion. Give me some time to think this over.

To see what the switches do is not very complex, just put the aircraft on a runway and open a second VC window. Now you can control the switches and directly see what the effect is. See the attached image how I do it.

Hi Mathijs,

Yes, that seems like one way of doing it and I will give it a try.

May I help:

Switch:

VV VAH = Display Speed - Altitude - Verical speed

VAH = Display Speed - Altitude

OFF = No Display of above items

Switch:

DED DATA = Display DED data

OFF = No Dispaly of DED data

Switch:

ATT = Display Pitch ladder - Flight Path Marker

FPM = Display Flight Path Marker

OFF = No Display of the above items

Switch:

DEPR = Navigate by Nav 1 radio

ON = Navigate by Nav 2 radio

OFF = Navigate by GPS

Switch:

CAS = Display Calibrated airspeed (a dererative IAS)

TAS = Display True airspeed

GS = Display Ground speed

Switch:

RADAR = Display Radar altitude (altitude over ground)

BARO = Display barometric altitude (altitude over sealevel, if set to local barometric value - QNH)

AUTO = Display Radar altitude when below 1500 ft above ground - otherwise display Barometric altitude

Switch:

DAY = HUD brightness for day

AUTO = Auto toggle brightness dependent on ambient light

NIGHT = HUD brightness for night

Thnsk Finn!!!

It should probably be added that DED data cannot be displayed on the HUD. We had enough of an issue getting 14 degrees of symbology on there vertically, and there just was not room for 3 additional lines of text, even when converting the bank scale from the standard bottom type to the one that's referenced (attached) to the flight path marker.

Can you see the DED data by moving your eyepoint? Or maybe it can be added so that's possible? For TrackIR users, it wouldn't be a problem to take a quick glance at it  I'm definitely a future TrackIR user.

Even with TrackIR, or shifting the eyepoint up manually, there's no way to avoid what we called a "cone of visibility," which Stefan and Mathijs did a wonderful job of expanding as far as it could go. It's difficult to explain, and believe me there was TONS of internal discussion on this, but basically, the (very cool, and unprecedented!!) collimation effect that was implemented in this F-16 means that there had to be something akin to a fixed mask in the HUD glass. And near the bottom of the glass, visibility ends a little below the bank angle scale, at the lowest, no matter how far up the eyepoint is shifted.

Trust me, I tried to get it on there. It can be done if the DED data font is reduced to an unrealistic, and frankly somewhat ugly size, but then I'm not sure the benefits of having it outweigh the costs. The other HUD symbology, which is very realistic, does not accomodate such a look very well. Plus... we figured that the DED data is not quite as important as the primary HUD data, and the DED itself is already very close to the HUD... so, the level of redundance in having it there and the pretty unattractive way it would have to be fit in argued against its inclusion at all.

Thank you Mr. Finn; I was looking for that in the manual ...

[Finn 873]

I actually wonder that You say that it isn´t described in the manual.

It´s perfectly described on page 32-33 !!

What is the common phrase in our community ? -->> RTFM !!

The manual contains 47 pages and there is text on ALL pages

By reaading it myself (I actually did yesterday) I could have saved myself typing the above description and simply made a copy and paste from the manual !!

Here we go to emphasize !!:

FROM THE MANUAL PAGE 32-33:

HUD REMOTE CONTROL PANEL

The HUD remote control panel determines what is shown on the HUD. Note there are two versions of this panel, depending on the model.

VY VYH / VAH / OFF

VY/VAH - display vertical velocity, velocity, altitude, heading plus Bank Angle Indicator

VAH - display velocity, altitude and heading

OFF - heading, velocity and altitude scales only as digital readouts

ATT / FPM / FPM / OFF

ATM/FPM - display the Flight Path Marker and the Pitch Ladder

FPM - display the Flight Path Marker

OFF - no Flight Path Marker and Pitch Ladder

DED DATA / PFL / OFF

DED DATA - displays DED data in the HUD

PFL -displays Pilot Fault List data (only in block 40/42 current, 50/52)

OFF - does not display DED data or Fault Lists data

CAS / TAS / GND SPD

CAS - displays Calibrated Airspeed

TAS - displays True Airspeed

GND SPD - displays Ground Speed

ALT RADAR / BARO / AUTO

ALT RADAR - displays radar altitude AGL (altitude above ground)

BARO - displays altitude above MSN (sea level)

AUTO - displays BARO above 1500 AGL, ALT RADAR below 1500 ft

DAY/AUTO BRT/NIGHT

DAY - full bright

AUTO BRT - automatic brightness leveling

NIGHT - sets half brightness

DEPR RET STB / PRI / OFF

Normally used to depress some information on the HUD.

We use it to select the source for the steering information on the HUD

STB - Selects NAV1

PRI - Selects NAV2

OFF - Selects GPS

TEST STEP / ON / OFF

- inop

Mr. Finn,

Sorry, I was using one of the 1st manual(s) Mr. Kok posted which was missing a few pages. Thank you for correcting me.

[saprintz 82]

Just to clarify something that may not be obvious:

"VAH"

This means show the Velocity, Altitude and Heading TAPES.

"VV / VAH"

This adds the vertical velocity scale, as stated.

In other words, you can have the tapes by themselves, but not the vertical velocity scale. It'll only show up if the VAH tapes have already been added.
