Climb Speed For The A320 Family

Sat Nov 13, 2004 8:32 pm

When you get off the runway,what's the climb speed for the '320 family?
After 10000ft do they speed up?
Thanks,
Ashley

Under US rules:
200 knots to 3000'
250 knots to 10000'
Above ten thousand, let the machine decide what it wants. It may vary between about 290K to as high as 340K.

One technique is to climb at high vertical speed into tailwinds aloft, and at high forward speeds if the winds enroute are headwinds. This can be done either by selecting a speed/mach or by selecting a higher or lower cost index on the performance page. The reasoning behind this is that if you are going to have tailwinds, you want to get up into them as soon as possible. On the other hand if you are going to have headwinds at cruise you should not be in such a hurry to encounter them and might as well make headway during the climb.

Vertical speed in the A-320 series is comparable to, say, a B-737 of similar loading, maybe a bit less. It may give 2500 fpm in the lower altitudes and be down around 800 fpm or so by the time you reach leveloff. It varies during any given climb quite a bit, and more than I recall any Boeing or Doug doing. Don't know why.
