I would be very grateful if someone helped me out with the slow speed Mooney settings for approach maneuvers, patterns, 3 degree slope descent etc.

I have trouble keeping this devil at a 100 knots to practice holds, intercepts and glide slopes.

Thanks

Hey Francesco!

The best resource for you comes from MAPA....

They have a training session... called PPP

The reference materials that come with the PPP training are specific to your plane...

Consider attending the PPP training and getting the book... it IS worth it!

https://www.mooneysafety.com

I know you are very busy with work... but this training is great for your health.... :)

PP thoughts only, not a CFI...

Best regards,

Don't rely on these #'s.  Get an instructor or safety pilot and fill in the Control and Perf. #'s for your plane. This Excel should be enough info to get you started.  While completing this you will be INSIDE the cockpit most of the time so get someone to help look for traffic.

I am assuming the question is about M20J manual handling on approach manoeuvres and that you can fly IFR in other aircrafts (tips by no mean for IFR flying)

I suggest you go to a safe height in VMC and get used to fly your aircraft at slow speeds (1.1, 1.2, 1.3, 1.4, 1.5)*VS in various flap/gear and engine config level & 5% descent/climbs & Rate1 turns, you will find that bellow 1.2*VS and above 2*VS the aircraft is unstable for handoff and needs accurate flying and lot of attention (on yaw nose at for slow speeds & low power vs roll nose down at high speeds & high power), at 100kts you may need gear down and precise ailerons/down pitch territory (also with power off you are near best glide speed and you will see -1000fpm), at 70kts the aircraft is a dog for IFR

Somewhere in middle should be OK, once you figure that speed, find engine power setting for level flight and +/-5% vertical gradients, most books suggest 1.3*VS for this task, you will also find that you can fly a +/-5deg heading corrections by rudder only instead of wrestling ailerons (this cheating on check rides but could makes life easier in real life at >70kts)

On M20J, hand flying in busy or turbulent IMC I go for 80kts gear down and 1/2 flaps with fwd trim, it flies level handoff at 25rpm & 17MP then +/-2MP for +/-400fpm for 5% descents & climbs, at 11MP engine is idle and I am at -800fpm and at 23MP I am at +1000fpm, at at that speed 15deg Rate1 turns may need some coordination but rudder is effective to kick them initially 

Once I am on ILS glide path, I keep full prop and 16MP+/-3MP initially depending on winds and chase needles with ailerons/pitch when it gets hectic

I know it is slow but I take my time, the whole thing from hold/IAF to landing is 10min, if you fly with big PFD and AP, skip this you can fly approach accurately at high speeds 160kts on max power as long as you ahead of buttons and aircraft and make that 5min :D
