What is fspilot.ini ? 

fspilot.ini is a small file within your FSXPilot home directory. You can open and edit the file with any text editor. The file is used by FSXPilot during prigram init and for saving parameters.

When a new program version is installed, your old fspilot.ini will not be overwritten. During the first start of the new program version, fspilot.ini will get updated (additional parameters). In general, it is a good idea to backup fspilot.ini from time to time. 

My latest fspilot.ini of FSXPilot as of Version 1.50 including support for Prepare3D's Raptor F22 and T6, all new planes from FSX Steam edition (acceleration pack) and some addon planes  looks like this:

[FSPilot.Aircraft]
;
; Section for all known aircraft in FSXPilot
;
; FORMAT: longname, model id, take-off speed, approach speed, cruisung speed, minimum speed, holding base leg, takeoff climb,  isheli (0 = no, 1 = yes), 
; bank sensitivity, pitch sensitivity, speed sensitivity, flare height(m), speed zero height(m)
;
; The maximum number of aircrafts supported is 640. Speed in knots. Climbs in feet per min.
; NEW: Bank sensitivity will affect the speed in which bank changes are made, same for the pitch parameter.  
; NEW 1.45: Speed sensitivity will affect the power in which throttle changes are made
; NEW 1.45: flare altitude (meters above ground) , throttlezero altitude (meters above ground) both for autolandings
; No spaces please and always commas as delimiters please. 
; 
; Add new aircrafts with a new ac number (second argument, f.e. LJ45) in this list.
; The best way is to choose a similar plane from the list, copy the line to the bottom of the list and
; replace the ac number x with x+1 (f.e. make ac24 to ac25), replace name and model-id, test-fly and edit changes to the parameters 
;
; Important: Use the model ID that is in the message box of FSXPilot upon loading the unknown aircraft !
; Important: Always use NEW AC numbers at the end of the list
