Question Wot?

Pif now I’m confused

The –200 is in question, but you said make sure that the text and figures are for –500/-400? And since you’re flying –200’s, and if –200’s don’t have the AUTO position (I dunno coz I’m on –300’s, never seen a –200 up close and personal) why the description if it’s not applicable?

I gather your pneumatics panel/switch/valve description is peculiar to the –200’s coz on the –300’s the engine bleed valves are on their respective DC buses, only the isolation valve is AC (#1 TRFR Bus). Additionally, on engine start, the corresponding engine bleed valve closes when the start switch is turned to GRD and does not open until starter cutout.

So what’s the big drama with closed bleeds on the –200 for engine start? … curious how the other half lives
