A220 Takeoff & Landing Profiles Guide

The V1 speed depends on two many factors to be given as a single value.

It depends on (but not restricted to):

  • Runway Surface (wet, dry, icy)
  • Mass
  • Balance
  • Altitude

What you can do is when using simbrief (a highly detailed flight planning website/app) is using the JBU template and you will find the V-Speeds.

Hopefully I guided you and gave you an acceptable answer, which applies to ALL aircraft, not only the A220.

You can use this but Simbrief will be more precise

Does anyone else feel like the engine power of the BSC3 in IF is really odd? I takeoff with a recommended thrust setting and reach rotation speed within seconds (this is an exaggeration but TO distance really is far to short) and then cannot climb at more than 1600ft/min without being able to hold a healthy climb speed. Interested to hear what other people have experienced

Yeah I noticed that too… I’m gonna do some testing. What speed are you aiming for at 50% load? This guide recommends 143 kts, but that seems really low.

Ok so here are the results. All tests were conducted under the same conditions as the guide’s tests. They were done at 50% load and with a takeoff thrust of 84% N1, followed by a reduction to 81% at 800 ft AFL, and then a pitch reduction at 3000 ft to accelerate through flap retraction and to 250 kts. This is an implementation of the NADP1 departure, which based on the fact that this issue is in the low speed regime, is the most performance demanding due to its longer low speed climb out compared to the NADP2 departure.

Flying at an initial climb of V2 + 10, 143 kts, my vertical speed was down to 1500 approaching 3000 ft, which I agree is too low. Later at 250 kts, my vertical speed was 4000.

At V2 + 20, 153 kts, that vertical speed approaching 3000 was much better: 1900. Still low though and my climb to 1000 was a little shallow.

By flying at 148 kts (V2 + 15) and delaying thrust reduction until 3000 ft, my vertical speed didn’t drop below 2100 during that segment. In addition, my initial climb was sufficiently steep. This seems to be the best compromise.

About the short takeoff roll, I think that may be fairly accurate to real life. PHNL has a long runway…
