A flight is planned for dispatch. According to the MEL, a defect means that the aircraft is not RVSM compliant and is limited to an level restriction of less than FL260. The final cruising level of FL250 is chosen. Which of the following statements is correct?
-
A
The flight should be cancelled due to non-compliance with RVSM requirements.
-
B
The aircraft must descend to a lower altitude immediately to avoid violating RVSM regulations.
-
C
The altitude should be replanned.
-
D
There is no further altitude restriction as the aircraft will not operate in RVSM airspace.
RVSM (Reduced Vertical Separation Minima) means an approval to operate in airspace where 1000 ft vertical separation is established between FL290 and FL410. For RVSM airspace, additional requirements on equipment apply in order to ensure sufficient vertical accuracy.
- In this case, the flight is planned to operate below RVSM airspace (FL250), therefore no altitude restrictions apply.
Looking at the answer options:
The flight should be cancelled due to non-compliance with RVSM requirements --> INCORRECT. As the aircraft is planned to operate at only FL250 (below RVSM) then there is no need to cancel.
The aircraft must descend to a lower altitude immediately to avoid violating RVSM regulations --> INCORRECT. As the aircraft is planned to operate at only FL250 (below RVSM) then there is no need to descend to a lower level.
The altitude should be replanned --> INCORRECT. As the aircraft is planned to operate at only FL250 (below RVSM) then there is no need to replan the vertical level.
There is no further altitude restriction as the aircraft will not operate in RVSM airspace --> CORRECT.
