Panel tilt on 1989 Bravo

[FlyDave]

I'm ordering an RC Allen 2600-3 attitude indicator but I need to know what the panel tilt is on my plane.

I can't find that spec anywhere. Does anyone know what the panel tilt is on a 1989 Bravo?

I would think it would be 0°. Most panels after the 201 were flat, and to the best of my eye at 0°.

Most gyros can handle a 2-3° tilt. Especially the new digital gyros. Nice choice by the way. I'm on my 2nd electric gyro. The -3 will be the replacement this time.

It's zero. That's what it was when I put my standby in. If I was you, I'd wait and get the Quattro from Sandia. No external battery box.

With two alternators and two batteries in a Bravo do you need that battery backup? If you get the backup make sure it is accessible as you are supposed to do a capacity test annually.

Andy - Thanks for the panel tilt. I called Mark at Top Gun earlier this morning and he said it was zero.

Jerry - That was my thought as well and I placed the order from Chief Aircraft this morning. Chief doesn't stock them and it's 2-3 week delivery time - but no tax on the order since they're in Oregon - so I'll wait. Pushes my IPC out.

Jerry,

 

There is only one time I can think when the battery would come in handy. Electrical smoke in IMC when you want to shut down the master and then your engine goes out, leaving you without a source of vacuum. I know, a lot of ifs…Probably an overkill, but Bravo is still a single bus system.

All true.   But if you have to shut down the whole electrical system, while in IMC, and then the engine quits, too, well, you sure are having a bad day overall.  

If you analyze the risk factors that face us as single-pilot operators flying piston singles you're probably better off to spend the money not on the backup battery for the #2 gyro but on training.
