LES Saab340 TQ readings

[isuruabeykoon]

I want to clarify the attached image. The TQ level mentioned on the charts and the actual simulation reading are different. I want to know if I am doing anything wrong.

 

Situation :

ECS : ON

AI : OFF

PRPM : 1250  

 

ALT : 9500ft

SPEED : 198

OAT : -10C

 

POWER : set to match the speed

 

TQ reading is : 58 - 59

 

But as per the charts page -19 of the Charts.pdf it indicates : TQ of 88

 

Please advice me if I am doing something wrong here.

 

Thank you

At 10,000 feet at max cruise power your indicated airspeed should be between 225 and 231 knots depending on weight.  Your indicated airspeed is 198 knots!  You stated that you have power set to match the speed...how did you determine the proper speed?.  This tells me that your power levers are not set properly and that is why the torque is too low.

See Page 77 of the Charts.pdf for the speed.

Thank for the response, Sorry I have been out of the desk.

I have set the POWER settings to match the 198knots which is given to me on the EADI - Isn't this the effective speed you should be set your power to? If not I am sorry I had no idea. I will check the Page 77 and will do a test flight during the weekend and post the results.

The speed displayed on the EADI is a "Flight Advisory Speed" for long range cruise.  When using the charts you are referring to, you need to set your power (torque) according to the chart (ie. max cruise power), not to match the EADI "Flight Advisory Speed".
