				Looking for the initial reduction/increase power change needed for climbs  or descents to keep the same airspeed? (example- landing at 120kts, aircraft is  setup at cruise to be at 120kts when reach OM, how much power would I need to  pull for every 100 fpm? so if it’s 500fpm it would be 5X that setting) 
  Thank you!

				If you are landing at 120 K, I hope you have a very long runway. Only partially answering your question, I get the following from my -10:
 
 17" clean = 120K
 15" clean = 110K
 12" & flaps1 = 85K with 500 fpm descent

				Here is a start I did for this.  Adjust as needed.
  
 I have been using 120 knots for initial approach, 100 knots at the IAP, and 87 knots at the FAF (full flap speed).

				You must not fly into very many busy airports. Why not fly 120 to Loc 
 intercept and 100 from FAF to DH? Most any precision approach will have 
 at least 7-8000 ft runway to get slowed down to land, and you are only 
 needing to lose 30 kts with flaps.
 I use 105 from turn on to final in my Mooney and that is due to gear 
 speed limit of 105, so I can drop gear at glideslope intercept. No 
 problem slowing from there to 70 kts over runway end with the same 87kt 
 flap speed limit as the -10. I don't use flaps until have runway in 
 sight. Makes for easier missed approach and better fit with faster traffic.

				I think if the weather is down to minimums you might want to come in slow to give yourself the best chance of seeing the runway.

				Before this goes off on landing approaches, I was using that as an example. I really should have asked what power change is needed at cruise to keep airspeed at (constant) for a 500fpm descent or climb. 
 I'll go out and fly around and figure this out. Was just trying to recall what a change of 1MP would do.
 Thx

				The traditional rule of thumb is 1" MP gives you 100 ft per minute, same speed.

				Yep - adjust approach speed as needed for the environment.
