Going up: 3rd E flat, 1st F, 4th G, 3rd A flat, 1st B flat, 3rd C, 1st D, 3rd E flat. To go back down, you would just play the notes in opposite order (i.e. E flat, D, C, etc.).
The slide positions for an E flat scale are 3, 1, 4, 3, 1, 3, 1(or 4), 3
1, 3, 1, 4, 3, 3, 1,1, 3, 3, 4, 1, 3, 1: F, A flat, B flat, B natural, C, E flat, F

Slide positions for B-flat tenor trombone concert pitch to middle C: C (6th), D(4th), E(2nd), F(1st), G(4th), A(2nd), B(4th), middle C (3rd)
A-flat Major scale
The Keys of B-flat, E-Flat, A-Flat, D-Flat, G-Flat, C-Flat, and F-Flat major all contain the note E-flat. F-flat major is a key which only exists in theory and not in practice, since there is a double flat in that scale (subdominant). The major scale with the most flats is C-flat major - with all seven flats.
The notes and positions for A-sharp are exactly the same as for B-flat.

A-flat Major scale
The subdominant in a scale is the 4th, which in the key of B-flat major is E-flat.
C flat Major
Your question doesn't make much sense. But for any scale, "do" would be the first note of the scale, which is whatever the scale is called. But for a flat major, from what it sounds like you're asking, the note would be a flat. Ex: In B flat major, "Do" is b flat.
e-flat major
The Keys of B-flat, E-Flat, A-Flat, D-Flat, G-Flat, C-Flat, and F-Flat major all contain the note E-flat. F-flat major is a key which only exists in theory and not in practice, since there is a double flat in that scale (subdominant). The major scale with the most flats is C-flat major - with all seven flats.
F flat is simple an E scale. You didn't specify so I will give you both major and minor scales with notes and positions in parentheses The formula for a major scale is wwhwwwh so the E(Fb) major scale would be E(2)-F#(5)-G#(3)-A(2)-B(4)-C#(2)-D#(3)-E(2) On my trombone, the B is usually in a #4 and the High E is also a tad sharp. The [Musical]Minor scale in E(Fb) would contain the following notes E(2)-F#(5)-G(4)-A(2)-B(1)-C(3)-D(1)-E(2). If you need help in these, just remember your formulas. The slide positions are chromatic(half step intervals). That should help you if you need to think of them on the fly.
