Diversion Due Weather.  An exec jet inbound to EGLF diverted due weather below limits.  EGKK would not accept the aircraft although it was the nominated flight plan alternate.  Some other alternates were also below limits but the aircraft was accepted at Southend.  ATC advised that they could only be accepted if they declared PAN.  This problem has occurred at other destinations worldwide; possible partial solutions would seem to be that if an airport cannot accept diversions this fact should be advised by NOTAM and flight plans nominating such an alternate should be rejected at the time of filing.  The wider problem is that if one aircraft needs to divert due weather  or airfield closure it is likely that many more will need to do the same and alternate capacity is limited.  (S).

Airspace Infringements (25)

S suggests that systemic improvements could be implemented.  Various factors were:

Inadequate planning (1)  Due time pressure and delaying factors, the instructor did not check the student’s planned navex.
Weather Factors (1)  Inadvertent entry into IMC.
Visually avoiding traffic (1)
Transponders over reading (2)  In one case the transponder Mode C fault was recorded as an allowable deferred defect which had been overlooked by the PIC. (S)
Lack of Knowledge (0)
Climbing too early after flight beneath a CAS base (1)
Take Two (-)
Misidentified surface features, lateral navigation error or misread the moving map (1)  The latter was the case.
Flying too wide a circuit or turning too late after departure (1).  Late turn due to simulated EFATO in twin.
Confusion of CAS bases (0)
Altimetry (3)  One pilot misread the altimeter by confusing the large and small needles. One set destination QFE while still beneath CAS and one had an incorrect QNH set. (S)
ATZ and gliding site infringements (7)
RA(T) (1) (S)  Pilot unaware of RA(T).

Student solo (2), Instructor on board (4)  It may be that some flying schools underestimate the time needed to prepare and brief for a navex.(S)
