Hey guys,

 

 Just a quick question since i am no 320 pilot. I really enjoy flying the FBW320 but it feels very powerful especially on inital climb out. Yesterday i took off close to MTOW and climb rates varied between 3000 and 4000 feet per minute. Taking the expertise of the FBW Team into account i assume this is the real planes performance isn't it?

Any comments on this?

 

Best regards,

Tom

Pass me the weight and conditions and I will see what I see for ya by the real charts

From memory, it was about 77tons TOW, 16° OAT and something around 1025QNH. Flex temp was 20°. Flaps 1+F.

Ok, I took a look and here is what I have found.

This data will be based on a old non NEO A320 with the CFM engines.

At 76kg at standard day conditions, it takes an A320 to go from brake release to 1500ft 2 minutes. It will take that same aircraft to go from brake release to 5000ft 3 minutes. If you average this and do the subtraction, you are looking at about 3500ft per minute to go from 1500 to 5000ft. That falls in between your 3000 to 5000ft per minute. Now, we know at those altitudes there will be configuration and speed changes. To get a good comparison, lets compare your findings against this measurement. From brake release, we are looking at a 76kg aircraft taking 27 minutes and 175nm to climb up to FL350. Use standard day conditions at an airport at sea level. Don't flex and ensure to accel to 250kts passing 1500ft, 300kts passing 10000ft and maintain mach .78 once 300kts and .78 meets. Report back the take it takes to get to FL350. The FBW 320 tends to use 290 in the climb so hard select it to 300.
