Peak rate of climb. Performance question.

Hi.

 

What is the difference between climb speed schedule and peak rate of climb?

Other question: Is there any intermediate power settings for the climb? or it is performed at mil. or max. power only?

 

Thanks.

 

Antonio.

AFAIK they are different ways of expressing the same thing.

 

With the speed schedule - you monitor your airspeed/altitude and adjust the aircraft's pitch to maintain the desired speed.

 

With the climb rate you monitor your VVI/altitude.

 

Other question: Is there any intermediate power settings for the climb?

 

Not AFAIK but you might climb at a speed determined by ATC, other air traffic or to give 'wiggle room' for your wingman, etc. to keep in formation.

 

or it is performed at mil. or max. power only?

 

The "F/A-18C Performance Charts" have Climb schedules for Mil. and Max. Thrust.

 

I'm not sure which schedule DCS's FPAS uses but I usually climb using Mil. Thrust @ 360 kts/M0.8 (assumes DI=100).

According to some squadrons' SOPs you usually climb at mil and 300 kt CAS until 10000. From them onwards shallow out a bit to accelerate to 350 and continue climbing at that indicated airspeed. If you're going to a high cruise altitude you'll want to transition to mach somewhere in the low 20s.
