Hi Reto.
Well i went up to 3000m and the glide angle was set exactly to
"DESCENT_PITCH" which was far too much. I made some more tests and each
time the glide angle was equal to whatever
the "DESCENT_PITCH" was set to.
When i disabled the Aggressive mode everything was perfect and the glide
angle was automatically
set to 10 degrees which btw was the correct value for the intended glide
slope.
I implemented an emergency flight plan when the "fuel" level gets low
which calls for a fast climb to
an altitude calculated from the airplane's glide ratio and then a glide
back home.
Obviously if i am 30km out the glide altitude can get as high as 5km.
(if this is possible as i check the climb rate vs the throttle setting)
I will see if i can solve the problem by increasing the "BLEND_START"
alt error but i feel
that the aggressive mode should be disabled during gliding.
Anyway i found a workaround to this problem so my question was driven
only from curiosity.
Here is my Aggressive section:
<section name="AGGRESSIVE" prefix="AGR_">
<define name="BLEND_START" value="30"/>
<define name="BLEND_END" value="10"/>
<define name="CLIMB_THROTTLE" value="1.0"/>
<define name="CLIMB_PITCH" value="RadOfDeg(30)"/>
<define name="DESCENT_THROTTLE" value="0.1"/>
<define name="DESCENT_PITCH" value="RadOfDeg(-20)"/>
<define name="CLIMB_NAV_RATIO" value="0.8"/>
<define name="DESCENT_NAV_RATIO" value="1.0"/>
</section>
