FO did not Set MTOP

[Alti 65]

Hello,

in briefing i have set T/O PWR to MTOP.

After startchecklist the MTOP is set, for any seconds,

but while taxi and takeoff procedure the FO set this alwasy back to NTOP 90%.

when i press the MTOP button in the Dash, the FO set it back to NTOP90%.

Can you please tell me the exact point the NTOP 90 is being reset.

 

That when you press MTOP in the Dash manually without FS2Crew it still goes back to NTOP 90 is interesting.

 

I'm not sure if this is quirk of the aircraft or what.

 

Can anyone else reproduce this?

Thanks, I'll ask the Dash 8 aircraft programmer if there is any reason why the power setting would be reset to NTOP 90.

So I spoke to the Dash 8 aircraft programmer...

 

 NTOP is limited by 4 parameters:

Torque  <=100%
Nh <=100%
NL <=100%
ITT <=880

it will be reduced when any of the above parameters reaches its allowed
maximum



 MTOP has a cancellation timer. The logic is:

//  MTOP will cancel if PLs <60 and not in AF test mode >5 seconds

 This is to prevent using MTOP in any other conditions except for emergency

 

 

So there you have it.... can you see how you're triggering it now?

[Alti 65]

I wanted to use MTOP because I wanted to start on a very short runway.

But if for security reasons is not, then not.

 

thank you...
