Did you recently flew FS to Tunisia ? Have you the last chart up-dates, last routings, last ATC instructions...
You may notice that the JBA-TBK-SARDI-TABOT route is more often used with frequent shortcut clearances to procede direct to TABOT upon contact established with en-route ATC.
The TABOT-TANIT-MANEX(ex PORTO)-TUC and the TUC-TANIT-SARDI-TABOT routings are used by flights departing TUN or MIR with destinations Spain, France, and the UK.
Traffics northbound and southbound-with destination MIR-may expect a direct TOBIB(ex-SEPIA)-KENIS(final Rwy07) or a TOBIB-TABOT shortcut. A TOBIB-FARES shortcut is also possible for flights to South Africa, Cameroon, Angola, Namibia...
Flights routing via Malta FIR may file OSMAR-TANIT or TABOT-TANIT-MANEX-ICANI-CBN-SONAK...with a OSMAR-SONAK shortcut. A OSMAR-TANLI shortcut is possible for flights with destination TIP/Tripoli.
Shortcuts to points such BOLOT-AJO-TINTO-ELB-BALEN-GIANO-RONAB-CRN-MOS...are more and more cleared now.
Traffics arriving TUN/Tunis via CAR-NOLSI may expect a MANEX VOR/DME/ILS Approach when Rwy01 and Rwy19 are in use, otherwise MARSA pattern and 13 DME Arc is to fly you to Rwy29's ILS.
