Flight Planning Manual MRJT 1 Figure 4.3.5.
The following apply:
Temperature ISA +15°C
Brake release mass
62000kg
Trip time 5hr 20 min
Enter at 5.333hrs .... to ISA +15 .... across to ref line (Im at 5.55 hrs
now)
Now to brake release wt
curve, now down to MASS 62000kg (interpolate carefully) - across to fuel - right on 13500kg?
These are fairly standard
questions .... always think
carefully about the scale, units (eg decimal of hrs v
hrs and mins .... sharp pencil ...... and so on!!
