Throttle setting for cruising

[Vekkinho]

Hello everybody,

 

during my long experience with LOMAC, FC and DCS I've noticed that I usually fly with FullMil throttle RPM. If there was an app that records average throttle setting throughout the flight I'd be lik 95% of the time in Full Mil.

 

The only time I use AB stages in some let's say cruising flights is during climbout (if heavy and tanked). And I reduce to lesser RPM during dives and approaches.

 

I know this is also jet dependant (different jets require different RPM envelopes) but no matter of fast jets I use in DCS (F/A-18C, F-16C, F-15C, MiGs and Sukhois) I usually spend most of the time in Ful Mil. 

 

Seems that IFR formation flying also requires Ful Mil to catch up and sligtly less of a throttle to slack so my IFR throttle range is also in Ful Mil or just a bit lower.

 

So I wonder how accurate is this compared to real jets throttle usage, do they also cruise with Full Mil.  

 

Best regards all.

Nope.

From my frame of reference:- F-4 can attain well over 500kts at full dry and below 4000ft, but average (frugal) cruise would be around the 360kt  - 420kt mark.

Similar higher up also.

Tornado similar if anything but capable of a lot quicker down low, it just depends on why you are cruising - are you just stooging around or are you going for distance and need to be frugal?

Just because it ‘can’ do it, doesn’t mean you have to all the time.

Cruising is typically done with a best range profile, which is based on AoA, not throttle setting specifically. But it's basically never full mil power. Often something like 0.75 - 0.8 mach at Angels 30 or so but varies by plane.
