Decent rate penalties

<< < (3/5) > >>

EHM-0948 Bruno:
Hi Bruce,

Are you using PMDG 737-800 right ?

That happens because when you take off, the airplane goes with too much speed (normally it's rare to do a re-rated thrust take-off) and the airplane compensates the speed with climb rate.

What you need to do is to set your FMC for a CLB-2 take-off and climb mode. Basically it's the second screen on the INIT REF sector.
After that, set a climb TGT speed of 285kn.

The first part (CLB-2) will give only 82.7% of power on the take off and climb until you reach FL180.
After that value, the airplane passes to CLB mode (full thrust mode) to give you all the possible thrust. Again he will climb much if you don't set a high speed value to compensate the climb rate.

Hope it helps.

Thanks for that Bruno. I've been wondering for quite some time how to get around the problem of the 737 (PM in my case) climbing at a silly speed.

EHM-0948 Bruno:
Hi,

Normally the full T/O thrust mode, or the "x"-1 modes,  are used on bad weather where the airplane can shake a bit and loose some power due to strong winds or head winds ... So, we compensate it by a full power thrust.

So, for normal weather take off and climbing, I always use CLB-2 mode, even if the airplane is fully loaded (100% payload, 100% fuel).

Also, don't forget that the airplane will take some time to climb so, it will follow the SID in a much more good way (don't you ever wonder why you got to the ceiling SID altitude on a waypoint too fast ? ;D ).

Regards,

Try a full ILS  DME east approach into Innsbruck and see if you can do that with out the dreaded v/s greater than 4500ftpm.........haven't succeeded yet, hence my woeful score so far!!

EHM-1651 Christian:
Well it must be possible most mediumsized jets like the B737 doesn't have an max decent rate of over 4500ft/m
