Default L39-C simple ADF navigation mission

Following on from John's navigation tutorial found here
http://forums.eagle.ru/showpost.php?...20&postcount=1

I have done a simple navigation mission. Doesn't take too long to complete and it just helps to learn the procedures. Last NDB in briefing is buggy so ATC will need to be called for heading to final destination.

Enjoy

Seriously? No standard ADF with movable scale? No RMI? Can you use HSI for NDB nav?

You can use the HSi using the RSBN whitout any station selected.
Example:
set RSBN channel 1 or any channel without signal. In the Caucasus you have 36 empty RSBN channel in the selector
Set approximate distance with the distance selector
Set approximate heading with the azimuth selector.

Now you have distance and heading (approximate) to any point you want.

And yes, real RSBN works in this way in manual mode.

Regards.

I don't understand, can you provide more details or external reference? Would like to read more.

External references about the RSBN "manual operation" or better "dead reckoning navigation":

Aero manual: Page 1-74: http://forums.eagle.ru/showpost.php?...80&postcount=2

ED L-39C manual (beta): pg 133

MiG-21bis Operational Manual pg.44

Sorry for my english.

Hi Nikola, Sorry for the delay.

These are the steps for a simple navigation using the RSBN in manual, RSBN in manual +ARK and finally RSBN in auto mode.

Navigation with the 39 using different systems.
From Anapa to the Bay of Gelendzhik, to Smolenskaya and landing at Krymsk.

1st leg: Anapa to Gelendzhik Bay: RSBN in manual mode, no land signal from a station.
With the plane started, we set the RSBN distance via the distance selector: 72km and set the azimuth via the azimuth selector: 132º
We´ve got indications of heading (HSI) and distance (the drum counter bellow the HSI)
If we follow the indications, we reach the Gelendzhik bay.

2nd leg: Gelendzhik – Smolenskaya. Using RKL-41 and RSBN in manual mode.
We tune the ADF of Smolenskaya (662) and set the distance from Gelendzhik bay (68km) and estimated heading (63º)
We can navigate with the RKL-41 and with HSI indications and distance indication.

3rd leg: Smolenskaya – Krymsk. RSBN in automatic mode with a land signal.
We tune Krymsk RSBN (28) and PRMG (26), distance is computed automatically. We also tune Outer (408) and Inner beacons (803) for a more precise approach. ADF in auto mode.

Remenber that the Auto mode only change between Outer and inner Beacons automatically IF you are in path AND landing gear is down.
If these parameters are not meeting the ADF will point to the outer station for a new approach.

Contact Krymsk for the active Runway. Landing with SDU mode connected for a moving marks in the ADI.

Sorry for my english.
