Why was a booking blocked?
A blocked booking always tells you the reason. Here is how to read it and what to do next.
Last reviewed
A booking is blocked when something it depends on is not valid at the time of the flight. FlyerOS never blocks silently, it shows the reason in plain words, so you can fix the cause rather than guess.
Reading the reason
Each reason names the thing that failed and why. For example:
Requires a valid Class 2 medical: expires 3 September, booking is 11 September.
That tells you three things: what is required (a valid Class 2 medical), the fact that failed it (it expires on the 3rd), and the moment being checked (the 11th, when the flight is). The fix is to record the renewed medical, then the booking clears on its own.
Common reasons
- A licence, rating, medical or currency has expired, or will have, by the date of the flight.
- A prerequisite is not complete, the student has not finished an earlier exercise the booking needs.
- The instructor does not hold the privilege for what the booking is for.
- The aircraft is unserviceable, or due for maintenance before the flight.
- A duty or rest limit would be exceeded.
What to do
Fix the cause the reason names, record the renewal, complete the prerequisite, choose a different aircraft or instructor, and the block clears. If the situation genuinely warrants proceeding, some blocks are warnings that an authorised person can override; see Overriding a warning, and who may.
