1. A monitor for a flight management system of an aircraft, said monitor comprising: at least a first module for recovering versions of data residing in memory of said flight management system in relation to flight plans and trajectories of said aircraft, anda second module for performing at least one test of said data at an output of said first module,wherein, said second module is configured such that, when one of said versions of the data residing in memory has changed in relation to a previous state, said at least one test is performed with respect to conditions of validity of said data to be satisfied for avoiding erroneous execution and/or abort of subsequent phases of said flight plans and trajectories, and allowing interruption of said execution if said at least one test is negative. 2. The monitor of claim 1, wherein said second module comprises a library of tests to be executed each in a given configuration of the aircraft and of environment. 3. The monitor of claim 1, further comprising a database including results breaching conditions at the output of said second module and of contexts of occurrence of said results. 4. The monitor of claim 3, further comprising a generator of messages of report of the results breaching conditions at the output of said second module. 5. The monitor of claim 4, wherein said generator is configured for parameterizing sortings and filterings at an output of the generator and at an input of an interface for presenting said messages to a crew. 6. The monitor of claim 4, further comprising elements for archiving said messages according to a download protocol. 7. The monitor of claim 4, further comprising elements for correlating the messages at an output of the generator with other messages originating from other devices for monitoring of the aircraft. 8. A method of monitoring a flight management system of an aircraft, said method comprising: at least one step of recovering versions of data residing in memory of said flight management system in relation to flight plans and trajectories of said aircraft, anda test and control step of performing at least one test of data at an output of said step of recovering when a version of said data residing in memory has changed in relation to a previous state, said test being performed with respect to conditions of validity of said data to be satisfied for avoiding erroneous execution and/or abort of subsequent phases of said flight plans and trajectories, and for allowing interruption of said execution if said at least one test is negative. 9. The method of claim 8, wherein said test and control step is triggered when the conditions of validity of said data are satisfied, said conditions being verified in a cyclic manner at an input of the test and control step. 10. The method of claim 8, further comprising a step of recording the results breaching conditions at the output of said test and control step and the contexts of occurrence of said results. 11. The method of claim 8, further comprising a step of generating messages of report of the results breaching conditions at the output of said test and control step. 12. The method of claim 11, wherein said step of generating comprises parameterizing sortings and filterings at the output of said generating step and at the input of a step of presenting said messages to a crew. 13. The method of claim 11, further comprising a step of archiving said messages according to a download protocol. 14. The method of claim 11, further comprising a step of correlating the messages at the output of the generating step with other messages originating from other steps for monitoring of the aircraft. 15. A flight management system monitor for a flight management system of an aircraft, said monitor comprising: at least one module for recovering versions of data residing in memory of said flight management system in relation to flight plans and trajectories of the aircraft, anda test and control module for performing tests of data at an output of said at least one module, said tests being performed with respect to conditions of validity of the data residing in memory of said flight management system, wherein said tests are to be processed in relation to said conditions of validity recovered in advance of said processing, said conditions of validity having to be satisfied for avoiding erroneous execution and/or abort of subsequent phases of said flight plans and trajectories, and for allowing interruption of said execution if one of said tests is negative.
