Default NDB presets gone?

Hi, i've been years without flying the 15 and now i've tried to edit a mission in the editor and found out i don't have the option to set the 3 NDB presets anymore, they are gone from the mission editor options when you select the plane. Is this OK or just a bug?

AFAIK the 3 NDB preset functionality has been removed (source Chuck's Guide).

Chuck's guide is incorrect. The 3 NDB buttons act as the range selectors (low, mid, high) when the Far/Near switch is in the near position. The official Mig-15 manual has not been updated to reflect this.

Chuck's guide is correct, the ability to pre-configure 3 NDB frequencies in the ME was removed several versions ago i.e. the ME radio page.

Old Preset functionality (now removed)

While the 3 switches may have been give a new undocumented function, this was not what the OP asked about.

Default Still no NDB presets for "Near" Beacon

Hallo

I truly hope it's a proper channel to request repair in NDB 1/2/3 presets. Currently MiG15bis works only on "Far" NDB. One cannot set a proper frequencies for "Near" NDB in Mission Editor. As a result switching Near/Far makes no sense.

If (by any other possibility) it's a new feature - can I ask for explanation what are NDB -1/2/3 now for? I found them useless, but I may go wrong...

TL;DR:

The switches set the frequency range for the "Near" NDB.

2. 310 - 640 kHz
3. 640 - 1300 kHz.

Note that receiving the second Senaki NDB (f = 129 kHz) with the ARC-5 is impossible, because 129 kHz is outside of the ARC-5 receiving range of 150-1300 kHz.

The ARC-5 contains an electrical motor for switching between the three frequency sub-ranges.
Electrical motor control depends on the setting of the NEAR-FAR NDB switch:

1. When the NEAR-FAR NDB switch is set to FAR, sub-ranges can be switched by rotating the three-position frequency band switch on the ARC-5 panel.

2. When the NEAR-FAR NDB switch is set to NEAR, sub-ranges can be switched by the three NDB switches 1-3 on the near NDB frequency range control panel (and not by the three-position frequency band switch).

The flight manual has to be edited to reflect this change.

Hello

Thanks for an answer, but It's not helping. It doesn't explain how exactly shall I use ARK 5 in flight. I red posts placed in topic and I red all the manual. Repeating it here creates no added value. Also it doesn't explain how the hell can I set Near and Far beacon in ARK 5.

Previously it worked just fine. One set everything in editor - done. Currently "Near-Far" switch makes no sense (nor has it NDB 1 - 3 switch) since it's quicker to set proper range on ARK 5 panel. Precise frequency one has to adjust anyway... being on final approach ...



Current working of ARK 5 isn't close to the real one (previous was just fine - one set three presets in editor - NDB 1 = Near Beacon for primary AF, NDB=2 Near beacon for backup AF, NDB 3 = left usually free).

How do you actually imagine to use NDB in flight right now? Can you please revert to the previous state? Or is there any other way to have preset for Near and Far beacon but i somehow didn't figured it out yet. So far there is no logic in current solution.

I bought a working module, and someone broke it down. It's highly unexpected.

With my best regards

Currently the ARK-5 works as the real one.

Basically you turn the frequnecy for the "FAR". This is the "main NDB" for navigation purpouses.

To make an NDB apoproach, you dial the "FAR" frequency and the NEAR is set automaticaly when yopu select the appropiate "Sub-Sector".
The 150-1060 general frequency range is divided in 3 "Sub-Sectors":
1. 150 - 310 kHz
2. 310 - 640 kHz
3. 640 - 1300 kHz.

For exemple, if you turn the ARK-5 to 150, for the "NEAR", if you select the Sub-Sector II: you get the 310khz freq, if you select the Sub-Sector III you get the 640 freq.

In this example, 150 is in the 1st Sub-Sector, so you can´t get the 1st sub-sector freq. for the 150-310 FAR freq.

So for an airodrome with 150-310 (outer-Inner) beacons, you dial 150 in the ARK-5 and select the Sub-sector II.

Note: if you select more than 1 Sub-Sector, the ARK-5 will broke, because the antenna will try to find 2 freq at the same time.
