"

"Hi David Yes, - it's on 'climb' and 'speed' I change it shortly after take-off. On the INC to LAX leg I didn't use EPA, as I was quite heavy, I just used the power manualy, and then set climb and speed after take-off. It seems to be more to do with the VS and Alt Set, than the speed thingy. I'll have another go this weekend Thanks Andrew, - I'll do that Regards John"

Once I establish a climb, at around 2000ft, if I'm really heavy like those 6,000 miles hauls I do, then I don't climb more than 500 fpm. That way I can maintain speed, and not have to firewall the thrust just to prevent a stall. I keep the shallow climb all the way to cruise altitude if necassary, only increment the V/S slowly, untill the speed starts to drop, then I level out just a notch on the V/S. I'm usually about 820.000lbs at takoff, there abouts. My last KORD to RKSI was with 125,000 payload, 340,000 fuel and the A/C. good luck. "

"David I change it from EPA to SPEED just after take-off, and control the climb and speed by adjusting the vertical speed to give the best climb and stay around 250 kts. with the set EPR. - rather than juggling the thrust all the time. From 10000 to about 30000 (depending on weight) I use about 300 knots and adjust it the same way. What is the difference between SPEED mode and IAS mode? I just tried another take-off from EGLL, and it did the same - went madly nose-up as soon as I selected ALT SEL and VS, I had the throttle window open at the time and saw the trim go all the way nose-up then start to come down again, by this time it had almost stalled. I went back on manual to control it and, after getting it settled down again, selected ALT SEL and VS and everything went OK. Dunno what it is with the trim, never mind I'll try it again later. Cheers John"

Cheers John [right][snapback]8856[/snapback][/right] <!--QuoteEnd--></div><!--QuoteEEnd--> Need a bit of clarity here - there seems to be a mix-up between the modes that are used for Climb control and those used for the FFRATS. The FFRATS has three major modes EPR, SPEED and MACH - these are (in simple terms) used to control the engine thrust and have nothing (directly) to do with climb control. In EPR mode the thrust will limit itself to the max EPRL selected In speed MODE the thrust will try to maintain the air speed selected In MACH Mode the thrust will attempt to maintain the aircraft at best MACH dependant on height, temperature etc. The vertical speed (climb or descent) are controlled separately and independently of the FFRATS setting using two possible modes:- VS - vertical speed required in fps - manually set your target flight level and then select the vertical speed required. IAS - the CURRENT IAS will try to be maintained by varying the vertical speed until the target flight level is reached. These two separate controls will interact, so if you have the FFRATS set to EPR and the Climb set to IAS, the aircraft will use the maximum thrust available up to the EPR Limit and maintain the current IAS by increasing or decreasing the rate of climb. This is the recommended setting for reaching cruise altitude as it uses the ""best"" (i.e. greatest but safety limited) thrust and you set the climb mode to AIS when you have accelerated to the best climb speed (usually about 320 knots depending on load etc). As airspeed is usually limited to 250 knots below 10,000 feet by ATC you will need to make some adjustments as you pass 10,000 feet. There is no point in using the FFRATS in speed mode and the climb control in AIS as the AIS climb mode will maintain a constant AIS and you (probably) want to get the maximum climb rate so you should really be in EPR mode on the FFRATS to get maximum thrust. Last point to watch out for is that at about FL260 the 742 may start to run out of power and you will see the vertical speed start to drop off (because it is trying to maintain airspeed it must lower the nose). If this occurs switch over to VS mode and select the vertical speed you want - but you will lose airspeed. I hope that the above is clear - the use of FFRATS is quite complicated and is NOT an autothrottle in the usually understood sense. "

"Barry Many thanks for that, it is many years since I read the manuals, and that is the best explanation I have seen for controling the climb. I tried it on my next flight, and it worked perfectly except I selected it at too low a speed to start with, and had to reset it to 250kts then about 300kts up to FL300. I found I had to bring the speed back as I went higher, as, it got up to the ""barber pole"". Just one thing; - I remember in the manual, or on one of the training flights, there is a time to select MACH mode on the FFRATS during climb, I suppose to stop that happening. Is that still valid? I had a strange one on the flyin too, after about 1 hour all the engines just stopped for no apparent reason, all the fuel settings and everything else I could think of were OK. I made a very average forced landing in the ocean! <!--emo&:wub:-->[img]style_emoticons/<#EMO_DIR#>/wub.gif[/img]<!--endemo--> Thanks again John"

"Barry, excelent post. However, over on the RFP forum, and I'll keep the details short here, a few people, (me included) seem to get a progressive ocillation in the IAS climb mode. In my case, it often results in the A/C nose diving into the ground to pick up speed. So, What works for me is to manually climb to about fl060, with only the FRATTS in EPR mode to fl020 and then speed mode there after. At fl060 I switch to ALT SEL with V/S climb mode. I know its not correct, but it works. John, Did you turn on your fuel tank heaters? I don't know if they truely work, or are for show, but the 1 time I didn't use them I had a 4 engine flame out at cruise alt. and could not restart, until I was about 6000 feet away from death. Just a thought. David Kenefick Pilot 1381 "

"David This was the first time I turned the fuel heaters ON, to see if they did anything, I've never used them before. I don't know if they had anything to do with it. No matter what, I could not restart the engines and ended up in the ocean. I used the IAS climb mode and it worked great , unlike when I used the SPEED and VS modes (as posted before). That's what gave me the huge pitch up and down to start with, but settled down later on. I left the EPR mode on, and it kept the engines at the EPR setting all the way up and, as I was fairly light, with a very quick climb. As I mentioned, I had to go to SPEED mode and reduce the speed selected because it was getting upto the barber pole overspeed warning. Regards John"
