Throttle process need help

Recommended Posts

Hi Guys can you explain this in the manual not sure exactly how this all works - thank you

 

=========================================================================================

 

FLC: The FLC button selects the flight level change mode (FLC). Maintains the indicated airspeed at the time the mode is
selected. Airspeed can be adjusted with the Speed selector knob. Selected speed is annunciated over the airspeed ribbon.
Note: This aircraft does not have auto throttle, the aircraft will catch the selected airspeed changing the pitch. It is recommended

to adjust the throttle to get an airspeed near the desired one before using this mode.

FLC Mode allows the aircraft to climb (or descend) at a selected indicated airspeed, as opposed to a selected vertical speed (VS mode).

 

It's much safer than VS mode for climbs, as it can prevent an inadvertent stall...which can happen if VS mode is selected and the aircraft is allowed to slow down while trying to maintain the selected vertical speed.

 

 

FLC Mode is not as effective during descent, and VS mode is predominantly used during that phase of flight.

 

Note that the Hawker does not have an autothrottle, and FLC mode operates independently, regardless of power setting. It will pitch the aircraft so as to maintain the selected airspeed. i.e. If you're at idle power and select FLC to hold 250 knots, the aircraft will descend at that speed....alternatively, if you're at full power and select FLC to hold 250 knots, the aircraft will climb.

So use to Boeing and Airbus this is much different - so if I am understanding this correctly if I stick to FLC which I prefer - I use the my physical throttle pretty much and FLC for small increments ? thank you

If you're familiar with Boeing, FLC mode is similar to LVL CHG on the B737, or FLCH mode on the 777.

 

For climbs, use your physical throttle to set climb power, and FLC mode will (if modeled correctly) pitch the aircraft to climb at 250 knots.

 

 

Likewise, if you are at cruise altitude and select FLC mode to hold your current speed, then reduce throttle, the aircraft will descend at the selected speed.

 

 

I believe the aircraft should also obey the altitude selected by the pilot (top right corner of the PFD). i.e. It should level off at that altitude once it gets there.

Thanks DB - have you tried it and is it working correctly ?

Tried it and it just about works. The response is a bit sluggish, and it's not very precise, but it's responding to power/configuration changes and is capturing the selected altitude.

 

I recommend stabilizing the aircraft at or near the desired speed / power configuration before engaging FLC. Pretty sure that advice applies to the real aircraft as well.

 

Cheers,

DB

Thanks for the info -hoping a good youtube video tut shows up it is a great looking bird

Note: This aircraft does not have auto throttle, 

You can add an auto throttle though if you use a Saitek Multi Panel.  Just change the cfg 

 

autothrottle_available= 0

autothrottle_arming_required= 0

 

to read

 

autothrottle_available= 1

autothrottle_arming_required= 1

 

I expect the purist will spit feathers for this suggestion, I'll keep my head down :)

You dont need a multi panel correct just assign a key = I have one but not using it - I saw post on  autothrottle_available= 1 but not the other entry maybe thats why it did not work - thanks give that a try

Well that did not work any ideas why - I set a key stroke to arm autothrotle but does nothing - thanks

Can't help you with key commands, I know it works perfectly using the Saitek Multi panel.

 

You do need to reboot FSX after changing the cfg for it to work.

I wasn't familiar with the Saitek Multi Panel, but just read the description on the Saitek web site. In light of the issues that the Carenado autopilot has, (auto throttles aside), this system would probably make the aircraft more useable in general...

Hmm I dont have that panel - have a couple others - oh well - are you using provided drivers with that panel ? are you referring to a PZ70 Pro ? thanks
