Bae-146 Questions...
Hi all,
Was watching a DVD on the Bae-146 (one of those flightdeck ones) which has raised a few questions I have been unable as yet to find answers to on PpruNe...
I was wondering where I might be able to find info about the TMS. Where does it get the variables from to calculate flex N1 settings etc as I didn't spot any kind of CDU in the flight deck a la Airbus for example? Also, the crew at one point used TGT as a measurement to maintain cruise thrust. How is TGT more favourable to use than N1 or EPR?? Surely TGT will vary with ambient conditions.
Also was wondering about the speedbrake selection. I understand it is an effective beast as it is used on the STOL operations. However, on the way into Ciampino, these guys had the thing fully deployed and then selected lift dumpers on the ground. Have seen many pictures of the 146 with the speedbrakes open whilst hurtling down the glideslope on approach to a long runway, so why deploy them?
Does anyone know where I might be able to get hold of a manual for the 146? Would be interested to learn some more about this a/c, plus add some strings to the bow for those airline interviews!!
Thanks.
