INS and Navigation using Waypoints

[ZHeN]

well, in that mission I used hot start from runway - INS was already aligned and I've checked the coords of inital point. everything was OK

[Fig]

hey guys! Thanks for all the input, i flew across the black sea map with different waypoints (manually set) using PREP keys and input coordinates. Also, i did the full alignment to class 1 (if im not mistaken)... It works!!! :thumbup: Thanks again to you all and thank you Zeus!:)

Please send me a copy of the mission.

Please send me a copy of the mission.

I didn't save it ...

I've found the problem already - I did not enter any altitude for my only waypoint.

 

So if you don't enter target altitude the WP would be at your flight plan altitude. But it wouldn't be 5Nm off...

the thing is, in that mission I didn't have a flight plan at all. the only waypoint was supposed to lead me to Roki Tunnel

If you entered the coordinates in PCN manually, it can be input error. That kind of things can happen easily to anyone...

Nobody else seems to complain about nav accuracy.

I can´t get this thing to work, I don´t know where to get the right coordinates, the aircraft starts with complete bogus coordinates (apparently), making a manual input absolutely needed(?) on every, single startup, it does not take the ones I offer it, only some arbitrary numbers far, far away from my position seem to be legit (opposite end of the parking space, a good 2km off) and I just don´t know anymore.

Half the stuff described in the manual doesn´t work and is contradictory, such as:

 

"7. The alignment process will abort if:

a. You click the PSM Mode knob to another position."

 

"8. You can check the alignment process status by clicking the PSM Operational Mode

knob to the TST position."

 

Not only does this NOT give me an indication as to how far the alignment is, it also aborts the damn alignment.

 

I just give up.

 

 

Edit: I think I worked it out, the Manual contains a typo...it is talking about the PSM Operation Mode knob but instead of TST (which is on the other knob), it means the one that has STS...this threw me off so hard.

- In the options screen, misc, select lat, long coordinates (keep in mind this will change, http://forums.eagle.ru/showpost.php?p=2826724&postcount=2664).

- Before starting the aircraft, verify your coordinates in the F10 or F2 views.

- Ask for ground power.

- Turn the battery and set PSM, set the mode selector to VEI and operational mode to N

- On the PCN, set parameter selector to L/G

- To enter the Coordinates (example N44.13.30 E043.04.42) in the PCN, first you press 1 ( to tell PCN you are using the first data block) the 2 ( to tell it is a north coordinate) then 441330 and press enter (INS). That took care of your north now to the east, first press 3 ( to use the right data block) then 6 ( to tell it is east) then 0430442 and enter.

- Set PSM mode selector to ALN and the PCN val light should light up, press it.

- Now finish the start and verify the rest of the way points and when is done the PRET green light is solid.

 

All of this is the manual with much details and much better explained.

Does anyone know where I can find the correct glide slope and runway heading information so I can enter it into the ins for ils/vor approaches? Heading is no brainier but I can't seem to find glide slope?

And the manual contains a typo that made me twist the wrong knob thereby aborting the INS alignment instead of checking it´s status. I have also had to change from Lat Long Decimal to Lat Long in the options menu to get the right data.

You will have to reverse this change with next update, as per last info from Zeus.

when is the right time to PREP WP00 ? before aligning or after ?

[fjacobsen]

You must enter that when in VEI, then after having entered, turn to ALN

[ZHeN]

I've noticed VEI isn't playing any role in this data entering process...

PREP 00 isn't really a waypoint. It's your actual position, both on the ground and in flight.

So in flight, if you want to know your postion, choose PREP 00.

The typo is on Page 90 of the flight manual under Standard Alignment step 4

 

4. Set the PSM Mode knob in ALM when you are satisfied that all aircraft position is

correct. Once the PSM is in ALM, the following will happen:

a. The ALN yellow light will blink.

b. The VAL button will light up.

I quoted the typo in my initial post, what is your incorrect input needed for? It only tells me there are more typoes in the manual.

 

To remind you, the typo that threw me off is: ""7. The alignment process will abort if:

a. You click the PSM Mode knob to another position."

 

"8. You can check the alignment process status by clicking the PSM Operational Mode

knob to the TST position."

"

 

The reason this threw me off is that there IS no "TST" position on the PSM Operational Mode knob, only STS, but there is a TST setting on the PSM Mode knob that will abort alignment.

So me following the manual led to breaking the alignment process.

Yeah, I thought I had it right the first time...well, the joy of WIP XD
