How to use this, Part II

eh?

seems like this is just an Alzheimer instrument........remind me what heading I'm supposed to be flying?!?

 

[Bonchie]

Looks like just a way to mark headings and quickly see your reciprocal if you aren't good at doing them in your head on the fly. Also points out VFR cruising altitudes given the direction.

so, the reciprocal of E is W, hmm.... interesting...

Say it isn't so!!! I've been doing it wrong this entire time... Oh, the humanity!

A built in metal landing calculator!

don't be jealous!

 

[frfly172]

That's a classic something.

 

[Gucci Pilot]

wow....a gauge for someone that can't do "plus two, minus two"

 

[bullwinkle]

I just fly at 6000' MSL regardless of heading. It's easier.

That would explain all the yelling the tower folks do when I enter the pattern...

2 + 2 = 5. Winston Smith says so.

Just tell them you're not going to listen until they can calm down and act professionally.

 

[rbridges]

those are nice to have, but they are very expensive to overhaul when they start to fail. you'll start to notice that reciprocal directions will drift by a degree or two.

Well, sure, but, but...

It appears to also provide the 90* heading on both sides...hence my landing calculator reference.

A DG without the G.

How does that work on a 010 heading

Seriously though, sometimes my brain just decides not to work. Mainly when I'm on the ground being quizzed by an instructor. In the plane if I want the reciprocal and my brain is lagging I just look at the DG or the CDI.

I'd guess the red/white needle indicates bearing to north/south in a vertical presentation, using the red-white practice of a standard magnetic compass. I think the green reference lines only are moved by the center knob, similar to the green lines on a sighting compass.

The instrument looks old so maybe it was from back in the day when DGs looked like this.
