This is a two part request:

1) Aircraft Profile - add ability to set different fuel values for VFR and IFR for each aircraft profile. An example for an AW109 helicopter would be say:
VFR
Start/Taxi 10kg
Contingency 5%
Final Reserve 80kg

IFR
Start/Taxi 20kg
Contingency 10%
Final Reserve 110kg

2) Route - add ability to set each sector to either VFR or IFR e.g.
A route with multiple sectors (Land Here)
Sector 1 - Biggin Hill to Battersea VFR
Sector 2 - Battersea to Oxford IFR
And so on

At the moment, the workaround is to create 2 different aircraft profiles, one with VFR fuel and the other for IFR. However, you can only specify one profile per route. If you decide to change the profile for a different sector, you lose any W&B figures you may have entered early on.
