B733 Classic Anti Ice Fuel penalty

[Arctaurus]

Does anyone know any references that give the actual fuel flows with engine and/or wing anti ice on compared to normal (ie off).

[mabrodb]

Increase total fuel flow during cruise approximately 150
lb/hr for engine anti-ice on or 400 lb/hr for engine and
wing anti-ice on.

For a B722 using JT8D-17 and D-17R engines, AFM vol 1 states
1- engine A/ice only....240 kg/hr(approx 528 lbs/hr)
2- engine&wing anti-ice....420 kgs/hr(approx 924 lbs/hr
for both engines

Engine anti-ice burns 90Kkg per hour, engine and wing anti-ice burns 250kg per hour.
