Single throttle owners and MRFCS question

[Rdiehl3]

Tried searching Forum for my question but I guess I could not find what I was looking for or I typed words for my search that could not find this question I have.

 

Question:

 

1) I have a Saitek X-52 with a single throttle device. As you all know the A-10 has 2 engines.

 

The other day I was practicing wind milling and apu starts in the air. I had problems bc it asks you to move the inop engine to off. When doing this with single throttle device both engines have to go back to set one to off, then I have to push the good engine back up to power back up. Is there a way to keymap each engine so I can bring a inop engine back by itself while leaving the good engine at power?

 

2)MRFCS: Did a practice flight trying to land in MRFCS. When I placed the a/c in MRFCS mode and waited till all hyd in system 1 and 2 was gone. It was a little hairy flying the plane, it had a huge tendency to pitch up so I tried trimming down with no luck, I was able to land but fighting the pitch up tendency all the way down.:joystick: Any thoughts why it pitched up so violently?

 

2nd attemped in MRFCS placed in MRFCS mode/switch... After 10 sec no control what so ever, nose pitched over doing negative G nose dive almost like a cuban 8 but not rolling over to wing level , I just fell outa the sky like I had no wings.:doh: Any input on what I may have done wrong?

 

Both times i had no damage and strictly for training purposes. Any thoughts or your expirences with either question would be great.

I use single throttle too (hotas cougar). When i have to control the engines separately i use the engine buttons on the keyboard, you can map keys for every control, buttons switches and so on

Don't have a Saitek stick, so I don't know what they're capable of. Can you program the X-52 so that you can choose with engine to control??

 

Assign one button to cycle through controlling both engines, left engine only, right engine only??

You may be able to select which engine to control with the X-52's software.

 

I wouldn't know how to pull that off and haven't really needed to, I just use the keyboard also.

If memory serves me right (which it often doesn't) enabling MRFCS will cause the plane to violently pitch up or down (can't remember which way), it'll do the opposite when you turn MRFCS off.

I also seem to remember reading that a pilot must stop using pitch control in MRFCS when they get below about 500ft AGL

My memory is not great but I did remember where I read something.;)

 

This is the Manual Reversion section from Paulrkiii's Emergency Procedures doc.

 

MANUAL REVERSION LANDING

Landing should only be attempted in ideal conditions and flight controls should not be degraded, maximum allowed crosswind is 20 knots, no ECM pods can be loaded on stations 1 and 11, and you must never use pitch trim for flaring the aircraft. If you cannot meet these conditions, you should eject from the aircraft. To perform an MRFCS landing:

1. Jettison all stores and flares.

2. Extend landing gear either normally or with AUX LG EXT handle.

3. Pull the EMER BRAKE handle.

4. Fly a straight in approach at 1.5 to 2 degrees with low sink rate.

5. When below 50 ft AGL, pitch response becomes degraded.

6. Maintain minimum airspeed around 140 KIAS to touchdown.

 

 

Thanks again Paul!:thumbup:

You can assign a modifier to the axis, I use RCTRL for Right Engine, and RCTRL for Left Engine, that way if you really need to you can control them independently for something like a windmill start. I cant say that I have ever had the chance to use them, but its configured just in case.

Just remember that, although you can use the keyboard (or a modifier) to adjust the left and right sim throttles independently:

 

- As soon as you move your physical throttle, the left/right sim throttle positions are immediately overridden back to the position of your physical throttle.

 

- To move either sim throttle from OFF to IDLE, your physical throttle must be pulled all the way back.

I use an X52 throttle myself, but, like Shu, I use the ctrl buttons for modifiers. RCNTRL+THROTTLE for right engine...opposite for left. Works beautifully.
