It has finally been decided that only these calculators will be allowed to be used in the pilot exams:

• Texas Instrument TI-30XS
• Sharp EL-W531
• Citizen SR-260
• Casio FX-83/85 series

And as they are easier to obtain in the US:

• Casio FX-300

Also, the flight computer must be either the Jeppesen CR-3, Pooleys CRP-5 or the AFE ARC 2.
