Hi,

I am working through the flight training lessons in MSFS and am stuck in the 'take off' and solo flight ones. Both lessons require you to take off and maintain a speed of 75kts whilst reaching a height of 5,000ft. The distance is limited to ensure you keep a reasonable angle of ascent.

Even with full power, I am unable to keep a steady speed of 40kts and can only get above 50kts if I begin descending, which is not good for your performance score.

Any ideas how I can achieve the speeds required?  

What is your climb speed? I don't know what kind of aircraft you are using but unless its an ultralight, 40kts is very slow and unless you are climbing >1000fpm you should be able to go faster.

Try disabling whatever controller axis you have assigned to throttle, then moving the throttle to full power with mouse in virtual cockpit. If that works then you have a controller problem (or assignment conflict). 

Feels like a problem with getting the right commands from your hands to the simulator. Are you using throttle hardware or just keyboard controls?  Make sure your mixture is full rich (in) and when your throttle is fully in, the tachometer is showing something in the range of 2500 rpm’s.

I have a throttle quadrant and have to move it in the full range of motion when I start up. 

I am using a Saitek throttle - I have reset the usb and checked that when my throttle is at 100%, the virtual cockpit throttle is also moved to 100%

I am flying virtually level to try and keep speed, but as soon as I nose up I cannot maintain speed.

 

If others are able to do these lessons without issue, then it must be a problem at my end?

Is this in the C152 at Sedona?  At those altitudes you will need to lean the mixture or you might not generate the right amount of power as you are running too rich. 
I pull my mixture back to 50%, or maybe even less than that, about 45%.  If this is the problem, you will see the revs increase immediately, and the speed will pick up.

Hi @chickster25.  Do you solve this?

Hello, Ive just got round to trying this again. Whilst the change in mixture did provide a bit more power, it is still impossible to remain at 75kts with the nose up. The only way i get anywhere near 75 is to fly level or drop the nose. 

Strange that Microsoft chose to use a place like Sedona for training which is at altitude

I cant see anything wrong with my controls, but I just dont seem to have the power that I should have?

That is strange!  I haven't done the challenges for about a year or more, but I wonder if Asobo's recent CFD, prop dynamics, and other changes have affected it. 
I will try the challenges again tonight to see if I can replicate your problem.

Yes, I agree, Sedona is an unusual choice for this as it is already at about 4,800 feet.

Ive had a few more attempts and I have had a better result by staying on the runway until my speed hits 75-80kts. This appears to give enough inertia to allow you to climb at the recommended speed -just!

If you take off when the trainer tells you (at about 55kts) then I cannot increase my speed once in the air.

It's been a while since I played that particular lesson but I did not have these problems then. Perhaps something has changed but it's also possible you try to climb too early and don't allow the aircraft to accelerate first. If the aircraft has a too high angle of attack it won't accelerate or climb.

When the instructor tells you to "take off" he problably means you to leave the ground but after you've left the ground the aircraft should be allowed to accelerate before you make it climb faster. 
The Cessna 152 has a Vy (best rate of climb) of 67 knots. You should allow it to accelerate to that speed before increasing your climbrate.
