Ok's Where does it say (if anywhere) that Air elementals, Spirits of the sky and Slyphs can fly?

If so and you channeled one, could you then fly?

Also what type of actions is it to manifest in "Metahuman Form" (as per the free spirit power) because the bit at the top say's Exclusive Complex, text say's Simple Complex. Standard Manifesting is Complex (Exclusive??), but "Animal Form" in both the bit at the top and the text say's it's Exclusive Simple.
[EDIT]Actually Just noted that Standard Manifesting is a simple action. So im guessing that using "metahuman form" is also a simple action[/EDIT]

Fluff note: If a spirit was in Metahuman Form (Human) but because it was a Great Form it had +1 reach, would there be anything wrong in saying the effect was from the form "weilding" a pair of extendable batons?? And thus would it be a huge stretch to give the spirit the dual cyber weapon advantage (+1/2 power) to use with it's Unarmed/ Martial arts attack??

I don't know if it's a listed Power for any spirit, but manifested spirits can move as they see fit right? Channeling a spirit wouldn't let your character fly though, because he's still meat.

Fluff: It could probably look like whatever, depending on the form the spirit took when summoned, but the rules and numbers would stay the same. Unless you mean something like an ally spirit.

As far as I know, they never really talk about it in 3rd Edition outside of Ally Spirits. I assume all spirits have the Three-Dimensional Movement power, and yes, I do allow magicians to use that power if they channel one.

Note that when using Three-Dimensional Movement you're limited to your normal walking speed, so it's actually slower than running or even using a spell like Levitation. I tend to give spirits oriented around flying or the air a running multiplier equal to half their Force (rounded up), though, but that's just me.

Shockwave IIc, you're confusing the term manifest (SR3.173 -- to become visible on the physical plane as a ghostly form) with materialize (SR3.264 -- to take on a physical form on the physical plane).

All manifested spirits can appear to be flying and to move through walls, as much as their astral form is free to move around in astral spalce in 3 dimensions.

I make the following interpretions of the rules: The only ones that can fly are Materialized spirits of the sky and air elementals. Ally Spirits, or Free Spirits that were formerly Ally Spirits, are the only ones that can 'walk on air' (3D movement).

Sorry, haven't studied the rules for Slyphs.

If an Air Elemental went free, I would certainly say that it could fly in its materialized form.

The only spirits I know that can routinely materialize in the form of a metahuman are Ally spirits. Ally spirits do not get any powers due to where they came from (e.g. nature spirit or elemental) so I believe they lose the power to fly, but they do get the power of 3D movement.

sylphs are basically air elementals. same stat mods, as i recall, and same powers.
