Challenger 350 Profiles Guide

JetMach and NetJets Challenger 350

Welcome to the Challenger 350 Guide

The Bombardier Challenger 350… one of the best, if not, THE best selling business jet in the world today. With stellar performance both on the field and in the air, this aircraft is sure to keep you on your toes and looking for that next adventure. The Challenger’s capabilities will allow you to depart from runways as short as 4000ft to a destination over 3000nm away thus providing you with endless routes and opportunities to explore.

Powered by two Honeywell engines, the thrust you will experience with the CL35 will amaze you with its climb performance as well as cruise speeds. You will often find yourself passing your fellow narrow-bodies while cruising at M.82. Venture in into the upper levels of the stratosphere where the rides are smoother, all the way up to FL450 and view the earth from another perspective.

Prepare yourself for what it feels like to fly in luxury with a beautifully crafted cockpit and cabin interior. Let’s dive in!

For the official Infinite Flight video tutorial please visit How to fly the Challenger 350 . I will also include the link of the tutorial below for quick access as you read through this topic.

This detailed guide, should get you into the air as well as on your way to a successful landing in just a few minutes. Please read through the notes sections throughout the topic as well as at the end of this tutorial for further clarification on some of the items found within the table.

Bonus: There is a Quick Reference Guide in this tutorial. You’re more than welcome to download and save the PDF for imminent and future use. Found under “Challenger 350 QRG”.

Takeoff N1% Setting

What power setting do I use?

I tried making it the least confusing possible, but I have added in N1 power settings. Power settings for the Challenger are a bit different than what we’re use to. They’re dependent as much on aircraft weight and runway length but more so the ambient temperature. Runway length is taken into consideration for shorter runways but for the purpose of this guide short runways are not considered when presenting values.

Instructions: Refer to your OAT readout to determine what power setting below to use for departure. Set your throttle position % to target the N1 ±0.5%

Temperature(C˚) Takeoff Power @ SL (N1%) Throttle Position %
-30 81.4% 80%
-25 82.3% 81%
-20 83.2% 82%
-15 84.0% 83%
-10 84.7% 84%
-5 85.5% 85%
0 86.3% 87%
5 87.0% 87%
10 87.8% 88%
15 88.7% 90%
20 89.5% 91%
25 90.3% 92%
30 91.1% 93%
35 90.3 % 92%
40 88.7% 90%

Note 1: Increase N1 setting by 1% per 1000ft of airport elevation until reaching a maximum of 94.8%.
Note 2: Maximum N1 for the Honeywell HTF7350 engines is 96.8%. 100% throttle in IF will stop the N1 at 96.8% per its real life counterpart.

Max Recommended Cruise Altitudes

Can I go straight to FL450? It depends…

Below are the maximum altitudes under a given flight weight and associated cruise speed. Often we’re able to get up to FL450 after the 2nd hour. By that point we will have burned off roughly 4,000lbs (1,814kgs) of fuel. I’ve also bolded the aircraft service ceiling which will indicate to you that you have reached as high as the aircraft is certified to go for that weight & speed.

Weight LBS (KGS) M.80 M.82
40,000 (18143kg) FL430 FL400
39,000 (17690kg) FL430 FL410
38,000 (17236kg) FL440 FL410
37,000 (16783kg) FL440 FL420
36,000 (16329kg) FL450 FL420
35,000 (15876kg) FL450 FL420
34,000 (15422kg) FL450 FL430
33,000 (14968kg) FL450 FL430
32,000 (14515kg) FL450 FL440
31,000 (14061kg) FL450 FL450
30,000 (13608kg) FL450 FL450
29,000 (13154kg) FL450 FL450

Note: Due to RVSM airspace ending at FL410, we don’t utilize FL420 or FL440 for cruise despite the charts indicating service ceilings under various weight conditions. That said, ATC IRL may issue block altitudes which permits us to operate in a 2000ft high sector of the airspace which would allow us to cruise at one of these even altitudes. Typically associated with airspace saturation would permit something like this or lack thereof.

Challenger 350 Specific Notes

Note: *APPR is available on this aircraft under 61% aircraft load

  • Landing flare pitch should be about 1-2˚ nose up.

  • Minimal flare is required. If you approach at REF + 10kts, and close off power at about 50ft, ground effect will naturally cushion your landing with just the slightest flare. Don’t flare like an airliner.

  • Descent rate should not exceed -1000ft/min on final approach. (-800ft/min is optimal)

  • Add 10kts to Vref/Landing speed in gusty conditions or in situations where steeper bank angles may be required.

  • No spool up is required. If desired to do a static/standing takeoff, do not exceed 60% N1

***Heavy Departures/Landings: Takeoffs over 75% may result in takeoff over Maximum Takeoff Weight (MTOW). This may also result in runway overruns. This could lead to overweight landings depending on your configuration and length of flight. Consider all factors and risks.


The Challenger does not have any leading edge slats. Therefore, a negative, downward pitch is to be expected when introducing flaps near the limitation or suggested speeds included below. Aircraft attitude will be near flat or just above the horizon on the final approach segment.

Speeds & Limitations

Flaps Speed Limitation Suggested Extension Speed
10 210kts 205kts
20 210kts 190kts
30 175kts 170kts

General Notes

Various notes from testing in the making of this guide. Other helpful pointers to ensuring maximum realism.

  • Climb Profile: Above 10,000ft, pitch for 280kts/or M.80 until reaching cruise. Once level in cruise then speed up to cruise Mach#.

  • For all takeoffs, Flaps 10 was used for data

  • 20% trim was used for takeoff. (30% trim was used for landings)

    • (Trim is personal preference based on how you calibrate and hold your device. Adjust as necessary)

Note: Fuel flow, thrust and other aircraft performance factors may apply.

Honorable Mentions

Huge thanks to Laura, Jarno and the rest of the team for another opportunity to assist with yet another Infinite Flight aircraft. I wish I could express the excitement that I had when I first found out that this aircraft was going to come to Infinite Flight. I was happy to help when they reached out looking for assistance with data and other reference materials. Really happy with the outcome of this product and hope all enjoy it as much as we all do ❤️

I hope you enjoy this aircraft as much as I did in making this guide! Now get out there and have fun! ✈️

Beta Testing Insight

Huge thanks to the Beta Testers! Lots of questions were asked which often prompted the need to fix an issue. There were two common phrases that was often mentioned on numerous occasions and it below is that phrase.

  • “This plane is so much fun, I had no idea…”

  • “I think this is my new favorite plane”

Curious to hear your feedback if you too can relate to any of the above statements. 😁

Editor Notes

Being fortunate to fly this plane as my full time job IRL and seeing the arguments from both sides or wanting something that has a longer range or that this plane is pointless, I’ve told folks,

  • “This is the plane you never knew you wanted but will come to love”

Give it a chance, and explore. It can literally get in and out of any airport and will most certainly surprise you with its potential. You’ll thank me later… or not. 😋

Hello everyone!

The day has finally come. The layout of the guide is slightly different. Notably power settings for takeoff. Please take some time to review through the guide to familiarize yourself with Challenger 350.

Good luck and let me know if you have any questions.



Definitely a fun aircraft! Does not disappoint. I really like the detail on the profile. Thanks for all the work!

Matt, out of curiosity are you starting #2 off the APU and starting 1 off x-bleed? Or do you keep the APU to start engine #1?

Both are started off of the APU. It gets complicated but above 9000ft we cross bleed start #1 due to the APU not being able to produce the pressure to crank #1. The bleed ducting to #1 is longer than #2 hence the difficulty to start in low pressure, high altitude environments


Couple of questions. Does the Challenger 350 use a 2 or 3 degree path for descent from cruise and is the Challenger 350 have a similar profile to the Challenger 300? Just asking as Simbrief doesn’t have the 350 as an option

Excellent article👏🏻👏🏻👏🏻won’t be able to benefit from the 23.2 update currently as I’m “On Leave” but thank you for the effort to make this informative piece!

Default is 3 degrees. If using Simbrief for planning use the CL30 (Challenger 300). The 300 is not quite as efficient and doesn’t quite have the range that the 350 has but its a good foundation for flight planning.


FL420 as cruise is hard to believe for this tiny jet lol.

Also what about throttle setting based off load%?

Rog thanks. Q400 APU doesn’t even give us bleed air for engine start so it beats me lol.

Its an odd one to grasp, but throttle is not based off of load%. Its based off of OAT (Outside Air Temp). Engines are powerful enough even at a heavy weight to get you off the ground with any of the power settings I provided in the Takeoff Power Setting section.


When I worked at an FBO I would hear challengers (what sounded like) starting their engines and then shut them off prior to their actual startup? Do you happen to know the reason for this?

That would likely be the bleed air being routed from the APU to the starter. It probably sounds like a woosh of air before if slowly fades out and then you hear the engine.


What’s the climb profile. Like how many ft per minute

It depends. We modulate our VS to maintain an airspeed while adding a slight amount of power as we increase in altitude. So down low after takeoff you could see values as high as 7000ft/min under light aircraft loads. But as you get higher, its not uncommon to climb at 300-500ft/min for the last few thousand feet or so above FL430.


What is the climb speed of the Challenger 350? 280, 290, 300kts?

  • 250 below 10k
  • 280 above 10k-FL280
  • M.80 above FL280 to cruise.

Accelerate to cruise speed once leveled off at final cruise alt.
