Does anybody know how accurate each of the stages are?

 

Thank you for your time

Cold and Dark with an unaligned INS, the aircraft is lost. The INS will give the wrong Lat/Lon coordinates for aircraft position and thus will be useless for navigation. The gyro compass, which control the HSI, ADI, HUD and VTB heading indicators will also be lost and assume that the geographic north is somewhere else.

 

The first 4 minutes of alignment is for the aircraft to find its true position and for the gyro to align itself to the geographical north.

 

At 4 minutes, you reach Class 4 alignment. That means that the gyro precession now creates a drift error of 4 nm/hours.

 

Each class reduces the drift error by 1 nm/h. So Class 3 = 3 nm/hour, Class 2 = 2 nm/hour and Class 1 = 1 nm/hour.

 

For emergency take-offs such as base defense, a Class 4 is the bare minimum.

 

To put an aircraft in QRA status, a Class 2 alignment is required minimum before the aircraft is put in QRA. QRA disconnects the electrical system to all the aircraft except for the two AC and DC emergency buses.

 

In the case of the INS driven heading indicators, there is an auxiliary independent gyro magnetic compass that can provide heading signals to the indicators.

 

This gyro has a three position switch:

Off: No heading signal is sent to the heading indicators.

Normal: The system automatically switches between the INS and the AUX gyro in case the INS is damaged. If the INS is unaligned, this position does nothing.

Aux: The heading indicators are controlled by the auxiliary gyro.

 

The AUX gyro is not to be used for waypoint navigation, etc. Its signals are not used for navigation at all. It just drives the heading indicators, bypassing the INS. So all waypoints coordinates, bearings, and other navigation aids are basically useless since they use the damaged INS gyro. The AUX gyro always provide magnetic heading and is there so you can get your aircraft back home after your INS gets damaged.

Thank you, I didn't notice :thumbup:

1. What should I do when I want Class 4 alignment ? I start as usual and then when PRET starts blinging, just switch to NAV ?

If so, then it ain't working. I switch PSM to NAV, PCN to N and it still doesn't navigate and PRET keeps blinging ...

 

2. When I don't want aligning at all, no class, just take off as fast as I can, whithout any navigation, how do I swtich to radio compass ? cause even heading on the hud is wrong

Have you tried to use the SEC mode? I'm not quiet sure what it does exactly, but maybe it is what you need.

 

I asked about it here: http://forums.eagle.ru/showthread.php?p=2847597#post2847597

But now answer so far.

Intel i7-12700K @ 8x5GHz+4x3.8GHz + 32 GB DDR5 RAM + Nvidia Geforce RTX 2080 (8 GB VRAM) + M.2 SSD + Windows 10 64Bit

DCS Panavia Tornado (IDS) really needs to be a thing!
