747 Classic pitch and power settings
 
Looking for a little help with a sim eval coming up. I've been given a textual description of what to expect but it may help if I can get rough pitch and power settings for:

4 engine straight and level
4 engine 500fpm climb/decent
3 engine straight and level
3 engine 500fpm climb/decent

Thanks in advance!

Oops sorry, I didn't mention that the sim would be a Classic with GE engines. I guess the primary power instrument would be N1...?

Ganbatte,

Clean? Dirty? weight? altitude?

configuration
 
Low altitude, say 5,000'. Clean configuration, about weight I don't know...whatever the middling weight would be.

Thanks

Start around 80% N1 and 2 deg pitch for the 4-engine straight & level. Vary from there as needed.

Pitch attitudes
 
I always remember pitch attitudes as a phone number

1030-56789-8531:confused:

10 deg, enroute climb 0 flap
3 deg,cruise FL300 - FL350
0 deg, descent
5 deg, holding level flight FL010
6 deg, 0 flap terminal area gear up FL050
7 deg, 1 flap, as above
8 deg, 5 flap, as above
9 deg, 10 flap, as above
8 deg, 20 flap, as above
5 deg, 20 flap, final app gear down 3deg glide slope vref+10
3 deg, 25 flap, as above
1 deg, 30 flap, as above

This is just in the back of my head to have something to aim at until we can get refer to the performance manual.:ok:

You mean A100 and A050? :ok:

anyone have the 'phone number' of the 747-400 :)

Turn the Flight Path Vector on without the checker seeing! Makes life so easy.

"Turn the Flight Path Vector on without the checker seeing! Makes life so easy"

Rainboe: i think that's is indeed a nice way to use your EFIS on the 400,

but I also wager on the 400 ( and 800) series ' The Queen of the Skies'
you probably can fly her off the cuff. I heard, despite that intimidating glare that Her Majesty gives to the 'Little guys like a 767-400:\, she's actually a little lamb on the flight deck :E

Thanks Cyco,

Could I be more specific,

2500' @ 270t trying to maintain 280kts with RR engines so I hazard a guess and think I will need EPR settings.

Regards Yellow

2-3* NU

Sounds like you're going for a sim eval too :ok: They'll give you the #'s in the briefing.

I use the T.L.A.R method............:bored:

(That Looks About Right) :}

yellowsub 8th Aug 2006 05:36

It' s a method I've used a lot too but it's a good idea to have some kind of idea of the basic pitch power settings in any jet. You wouldn't just rotate and wait to see what speed you ended up with would you? No, you go for 15 degrees cause you already know it's close to what you're gonna need. T.L.A.R is doing it the hard way mate, something I'll save for arsing about down route. I have a sim check for job and I've never flown 747 before......

Even grabbing an hour or two in the 747 classic sim is worth it if you've never flown a big bus before (a small career investment!). You can go thru the profiles a few times and practice your steep turns.

I would highly recommend knowing your powers & att's. You'll make so much spare time for other things instead of being reactive. Basic IF skills are about being proactive :ok:
