On calcule le MRB en appliquant la déclinaison magnétique au point de cheminement à la trajectoire vraie calculée entre deux points de cheminement. Les pilotes devraient utiliser ce relèvement uniquement à titre de référence, étant donné que les systèmes RNAV suivront la trajectoire vraie entre les deux points de cheminement. 1, record 1, French, - rel%C3%A8vement%20magn%C3%A9tique%20de%20r%C3%A9f%C3%A9rence
