Foreflight - Aircraft performance

[Stryk77]

Hey everyone, 

I recently purchased a 1979 Mooney M20K 262 Trophy.  Does anyone who uses Foreflight, have any predetermined aircraft performance profiles? I have been using the M20K 252 TSE, since they use the same powerplant (TSIO-360-MB1). 

Thanks.

I have a copy of foreflight snd not found any performance data supported. It would be nice. One of the operators I fly with requires a balanced field calculation done before each flight (based on current density etc) snd it would sure be nice if foreflight supported things like this.

There are models in Performance Plus. Don't know about balanced field length, but you could put in an enhancement request if they don't have it --- that seems like a pretty reasonable calculation to have.

Well, I have been through this voyage and regret to say there do not appear to be such profiles in Foreflight. One complicating factor is that your 262 is capable of flying in the flight levels and up there, will achieve speeds around 30 knots faster on the same power, as down in the lower altitudes. I had a version of Foreflight for several years that allowed putting in different profiles that the pilot could make up. I bought the highest grade (Performance plus?) because Foreflight created aircraft profiles, including some for the 252. But it regrettably does not consider what altitude you fly at, and that impacts both the duration of the climb and descent, as well as level cruise speed. You can make your own, I have some very rudimentary ones that I made for my aircraft at different altitudes.

I have found ForeFlight is receptive to suggestions. Write them an email with your suggestions, There is a better than zero chance that your feature will magically appear in a future release.

Agreed, I'm not sure if this was me alone, but at one point they removed the forecast discussion from the weather area.  I emailed them and a few weeks later they got it back into the next release.

I just looked in my Foreflight Performance Plus aircraft list and they have profiles for a M20K 252 TSE and it looks like every model A through V.

EDIT: I just tried the M20K TSE and it will calculate a flight using 6 different performance profiles and altitudes up to 28,000 feet.

Hey everyone, thank you for your input. 
 

I went ahead and contacted Foreflight, which they responded immediately and they are working on a solution. 
 

The aircraft is basically a M20K 231 with the 262 Trophy upgrade (power train only). 
 

I think we would looking at a mix of profiles of 231 and 252 (which has my power plant). 
 

Keep you all posted,

have a great day.

Another option for you would be to use the speed and fuel sliders to bump up the 231 performance if yours is faster.  I do this for my TN, reducing speed by 5% (TKS and imperfect rigging) and am usually within less than a gallon or .1 flight time.

I do the same on my bravo since there is no POH setting for 29/2400 which is what most people run at.  The factory poh only gives 32/2400 peak TIT.  I just dial fuel consumption up 10% and it all evens out.

I fly a Turboprop for work and use a pretty basic version of FF.  I just built multiple user defined profiles for the airplane at various power settings snd altitudes.  It’s only climb, cruise, descent, so not too difficult to figure and enter once.  Now I have about 10 built and available.  Plan my flight and pick the closest profile.  I have them named so it’s obvious what they are planned for.
 

TPs fuel burn varies greatly based on altitude and power setting, yet I’m rarely off by more than a couple gallons.  I think this method would work fine for a TC’d Mooney at many different altitudes.
