Heston
This person is quite nervous already of getting over flying one circuit!
I do not think that filling her head with the prospects of a 30 mile first solo cross country which must be so rare as I have never heard of one in 30 years will help her situation. As well as it will not happen!
I do not know where she is flying from but it is likely to be some small club airfield where the instructor can look for a lull in activities giving her the freedom of the circuit and no chance of a diversion due to runway closure or blockage.
I am sure its not Heathrow
