We charge £65 per hour incl VAT for dual or solo flying in a Warrior - plus nothing more for the dual training flight or any other flight with an instructor so that there's no financial penalty in asking for an FI to come along if the pilot thinks that the weather might be a bit of a problem for his/her/thing's abilities. BUT we Examiners charge an additional flat £65 for a renewal or revalidation proficiency check to encourage people to keep their licences valid by experience/training flight rather than by proficiency check!
