Cruise Performance vs Temperature deviation

[olmo 5]

PFPX handles cruise performance in accordance with the synthax used inside the Aircraft Type files. There are two ways to tell PFPX how to handle non ISA conditions:

1. Create an ISA performance table specifying how performace has to change every +/-10°C deviation through FuelAdjust=x;-x, SpeedAdjust=x;-x etc....

2. Create a performance table for every temperature variation provided by the aircraft performance manual.

At this time (ver1.15) there is a small bug affecting aicrafts performance tables created using the 2nd method.

Fuel Flow

Everytime a negative ISA table is present, F/F values shown are inconsistent and fixed to the one given by the 2nd temperature table inside the same speed range.

TAS

When only positive ISA tables are present, TAS values shown are inconsistent and fixed to the value given by the 2nd temperature table inside the same speed range.
