[deeteewan]

hi guys

does anyone know how to delete flight plans on cdu?

also how to delete waypoints and markpoints?

i having a lot of difficulties on that issue and i cant find it via the manual or perhaps i didnt search well enough

 

thanks

Waypoint Database

The EGI system provides point-to-point navigation with a maximum of 40 waypoints stored in each flight plan plus 25 letter markpoints. You can have up to 20 unique flight plans.

 

Markpoints

 Assigned waypoint letters A through Y (25 total).

 Can be copied to the mission waypoint database using Waypoint (WAYPT) pages and then modified as a new mission waypoint.

 There are two types of markpoints: an overhead mark and an offset mark. An overhead mark records the current aircraft position while an offset mark records the coordinates and elevation of a point identified by a sensor like the targeting pod.

 When an overhead or offset markpoint is created, the CDU will automatically branch to the Waypoint page to display the data for the new markpoint. This provides you with instant feedback concerning the new markpoint. It is important to note that the CDU will not branch to the Waypoint page if a Mark Z (weapon release) is currently being displayed.

 If all 25 markpoints are in use and another mark is taken, it will overwrite Mark A; subsequent marks will follow the same logic as above.

 

Flight Plans

 The CDU can store 20 flight plans with up to 40 waypoints each. A flight plan is automatically created in the mission editor or in the CDU.

 Functions only when STEER PT rotary switch on the avionics auxiliary panel (AAP) is in the FLT PLAN position.

You can insert new waypoints into a flight plan while flying a mission.

Waypoint Database Fields. Each waypoint is created with the following set of values:

 Waypoint Number: Number from 0 to 40 or letter from A to Z. No two waypoints can have the same number/letter. These are automatically set as Mission Waypoints in the mission editor or can be created while in a mission.

 Waypoint Identifier Name: Maximum of 12 alphanumeric characters; first character must be a letter. No special characters other than numbers or letters allowed in name except a period (―.‖). No two waypoints can have the same identifier. Set in mission editor or with the CDU during a mission.

 Waypoint Type: The navigation type of the waypoint as set in the mission editor.

 Waypoint Latitude: Stored as North or South degrees/minutes/tenths. Format is N/S xxoxx.xxx. Default is North.

 Waypoint Longitude: Stored as East or West degrees/minutes/tenths. Format is E/W xxxoxx.xxx. Default is East.

 Waypoint MGRS: Stored as Grid, Area, Eastings and Northings. Format is: ##N XX YYYYYZZZZZ.

 Waypoint Elevation: Number range from -1000 to +32767.

 Waypoint DTOT: Desired Time on Target, time stored as hours:minutes:seconds using a 24-hour clock. Format is HH:MM:SS; All zeroes indicate no DTOT entered.

 Waypoint Datum: This indicates the spheroid and grid data from which all coordinates are processed. WGS84 is always used.

 Waypoint Steer Mode: This can be set as: TO FROM, DIRECT, or TO TO. Set in mission editor.

 Waypoint VNAV Mode: This can be cycled between 2D and 3D vertical navigation modes. Set in mission editor.

 Waypoint Scale: This can be adjusted to display scale in accordance to ROUTE, APPROACH, HIGH ACC, or TERMINAL. Set in mission editor.

Great... but what about DELETING them as was requested?

 

As far as I know there's no way to delete either mark points, flight plans, or entries in flight plans. You can change what a particular wp# in a flight plan points to, but I haven't seen any means of reducing the number of waypoints in a flight plan.

 

Edit: I'm a liar, you can easily remove a waypoint from a flight plan by pressing the select key next to the waypoint entry (on the left side) and then pressing CLR on the CDU to delete it. You can overwrite it by entering a waypoint number into the scratchpad, and then pressing the select key. Note this removes it from the flight plan, but I'm still pretty sure you can't actually delete a waypoint, short of wiping the system entirely.

Beta 4 manual page 247

" Waypoint line select keys, R5, R7 and R9. Used to delete or overwrite flight plan waypoints"

 

I have never got this to work, and AFAIK it is not explained how.

 

There is a workaround I have found for deleteing unwanted additions to the original flightplan...

 

With page selector set to "Other", press NAV-->DTSUPLOAD-->ALL ORIG DATA (or any of the LHS options)

 

............. OR ...............

 

just flick the IFFCC off then on (reloading from the MFCD load page alone does not work).

 

This resets the original flightplan according to the DTC, but as nomdeplume laments it will not clear markpoints altogether or affect pilot created flightplans. It just deletes waypoints/markpoints that you have added to the original FP.

EDIT: I hope StrongHarm doesn't read this thread. He will just make me bow down and admit that the CDU reinits/reloads do have a practical use after all.

hi goshawk

thanks for your details answer

But as "Nomdeplume" mention in his post, what about deleting from DATABASE

the only thing that i succeeded is deleting waypoint and markpoint from FLIGHT PLAN,

but my wish is to delete waypoints from the DATABASE too.

and regarding Bipod`s post :"Beta 4 manual page 247

" Waypoint line select keys, R5, R7 and R9. Used to delete or overwrite flight plan waypoints"

tried it and it not doing anything and the waypoint is still available on DB

 

[deeteewan]

that is the problem :)

we cant find the way to do it ..

[Eddie]

You can't find a way to delete mark points because there isn't one. This is by design and true to the real aircraft.

 

And to be honest I see no reason why you'd need to.

[deeteewan]

i see

ok and what about deleting waypoints or clearing the DB ?

[BiPod]

And to be honest I see no reason why you'd need to.

 

You must just fly much better than me ;) "Oops, wrong button. Oops, wrong button. Oops again."

 

@ Nikola: The markpoints are named in alphabetical order, so the last one will be the highest in the alphabet unless you go past 25 and restart with A. Hope this is what you meant.

 

BiPod.

[Eddie]

I know that, but as you said. oops, wrong button, oops wrong button, did I marked that twice r not? :hmm: . And after half hour flight you simply loose count how many marks you did make?

And when you mark next few tgts (for example) you don't know what letter is designated to what target. You can visualy inspect, but it's not the fastest way.

 

 

Pen, paper. Problem solved.

[BiPod]

or I have to switch to markpoint and manually cycle through all markpoints?

 

AFAIK yes. Flick through and find the last one.

 

Or as Eddie says, pen and paper.

[StrongHarm]

Or situational awareness; a warrior's pen and paper.

 

Marks are designed to give you a view of points of interest on your TAD that can be referenced later. For instance; with JTAC I use marks to show the coords I've already run in on. After latching the SADL triangle that's transmitted, I call up the target on TGP, set it as SPI, then mark it. After my run I can get rid of that SADL triangle using the CNC OSB so I won't get cluttered, and I'll be able to see new SADL marks easily. I can then later see a picture of all the areas of the battlefield I've hit for JTAC by switching to mark as my steerpoints. If you have proper situational awareness, you'll see a pattern in your marks and they'll make sense. If JTAC is finished with me I can use them as a reference to run in weapons free. Let's say I hit a tank column at mark Delta. I remember seeing some artillery near that point. I can pull mark Delta up and run in guns. Also, if you just want a temporary reference so you can run in on a column with multiple runs, mark Zulu is always your last firing position. VERY useful.

The most useful aspect of marks for me, besides creating new flightplans, is using them to run in CCRP from high altitude. I do the following:

* Find target on TGP

* Make target SPI

* Mark the target

* Switch to Mark on the AAP for steerpoint

* Switch to your new mark and use the steerpoint tadpole to fly at the target with exact precision.

 

If I'm going to be doing turnarounds during a sortie and going out multiple times, I'm going to have a lot of marks. What I do in this instance is create new flightplans from the marks that are most important. For instance:

* Make marks on the map for ingress and egress points; move them to a new flightplan called Ingress.Egress (this is SA at it's finest because you can check the ingress path on TGP and make sure a ZSU isn't going to sting you in the ass during run in)

* Make marks showing all the AAA; move them to a new flightplan called AAA

 

Marks are not waypoints, but you can turn them into waypoints. Marks are the ELINT equivalent to a piece of scratch paper. Flightplans are equivalent to your finished notes. If you tried to study a problem using your scratch paper instead of your ordered notes, you'll take twice as long and most likely eat fail.

 

Using your ELINT SA assets looks like a pain, so I'm sure I'll get a lot of

Dude, I just want to drop some bombs and watch the flames! That's too much like school! <insert bong water sound>

.. but if you ask me, flying the A-10C without using all of its assets is like doing it missionary style in the dark every time; It's nice, but a school girl outfit and white knuckles go a long way!

What does R5, R7 and R9 mean???

"Waypoint line select keys, R5, R7 and R9. Used to delete or overwrite flight plan waypoints"

Row 5, 7, 9. I think. Makes sense to me, anyway. :)

 

The keys are on the left side, I updated my earlier post - it's easy to delete or overwrite a waypoint in a flight plan, but you can't actually delete the waypoint itself.

[EinsteinEP]

R5 is the button on the right of the CDU at line 5, while L7 would be the button on the left side of the CDU at line 7.

[nomdeplume]

R5 is the button on the right of the CDU at line 5, while L7 would be the button on the left side of the CDU at line 7.

In that case, the manual should be saying the L5,7,9 are used to delete or overwrite flight plan waypoints. In FPM mode, the right-side buttons open up the waypoint info but don't allow you to overwrite or remove the WP from the flight plan. You need to use the left side buttons for that.

Turn off CDU. Reboot CDU.

Cannot belive that there is no way to delete markpoint. I usually forget what is last markpoint I made. :doh:

 

How do you even find out how many markpoints you have made? Many times I have to guess if the last marked target is at markpoint 5 or 6... and the only way to find out is to start with a bigger number and try until there are no error messages of an unexisting mark.

1 - Pen and Paper.

 

2 - TAD.

When you create a mark point and then go to a specific CDU page (NAV? WP?), it will show the last mark point in the top left corner of the MFCD that was created. It will read something like MARK F +- and then coords, elevation etc. like it does for all points in space.

I know it works, just cannot remember the CDU page. But around 5 minutes ingame should clear that up.

Thanks man! Will try tonight.

Sure thing!

 

Usually I also write down the mark points and their content (A = Shilka, B = OSA, etc...) just to make sure. But as soon as you create a markpoint by accident, you cannot use that list anymore to know how many mark points there are.

 

Do pilots usually have pen&paper ready on their kneepad or anything? Or do they enter them into the CDU right away?

 

It's hard enough to copy the DISPLAYED coordinates that the JTAC gives you, but hearing them on the radio and writing them down while simultaneously flying the A-10 IRL can get pretty hectic, I suppose.

[Zenra]

You can also convert mark points to waypoints and give them a name in addition to their assigned number. That way you can use the CDU to search for (e.g., Shilka, ZSU,...) and call them up later rather than keeping a separate list.

 

Real A-10 pilots often write coordinates and other notes on the inside surface of the canopy with a grease pencil...
