The TK641 performed directly as an IST-LBV.
Etna volcano activation was observed along the route. Strong eruption at Etna, Aviation Color Code raised to Red, Italy.
Aviation Colour Code Orange indicates that a volcanic eruption is underway but with little or no ash being produced. Volcano is in normal, non-eruptive state. or, after a change from a higher level: Volcanic activity considered to have ceased, and volcano reverted to its normal, non-eruptive state.
Safety-related events and hazards or risks observed during operation that are not subject to mandatory reporting should be submitted as a Hazard Report. Hazard reports are used to obtain information about events involving potential safety risks during operations.
It is good practice to complete the EXTERNAL ENVIRONMENT AND METEOROLOGY report for a volcanic ash encounter.
Enroute
Even though extended VHF coverage by VSAT were implemented in order to increase AMS along the major flow of traffic we observed some difficulties to contact on VHF around FIR boundaries.
Some frequencies that we are used ...TUNIS 129.3 MHz, ALGIERS 124.1 MHz, NIAMEY 126.1 MHZ - 8873 kHz, KANO ...., DOUALA 129.5 MHz, LIBREVILLE 126.5 MHz
A listening watch should be maintained on the designated frequency (126.9MHz), 10 minutes before entering the designated airspace until leaving this airspace.
For an aircraft taking off from an aerodrome located within the lateral limits of the designated airspace, listening watch should start as soon as appropriate and be maintained until leaving the airspace.
Broadcasts Intervals
A broadcast should be clearly pronounced in English:
• 10 minutes before, entering an FIR within the IFBP region;
• upon entering and FIR within the IFBP region;
• as soon as practicable when departing from an aerodrome located within the IFBP region;
• 10 minutes prior to crossing or joining an ATS route or crossing an airway or waypoint;
• every 20 minutes;
• before a change in flight level;
• upon reaching the intended flight level;
• at any other time considered necessary by the pilot.
Use of SLOP is promoted in AFI region
KANO FIR Free route airspace (FRA)is available.This is a specified airspace within which users may freely plan a route between a defined entry point and a defined exit point, with the possibility to route via intermediate (published or unpublished) significant points, without reference to the ATS route network, subject to airspace availability. Within this airspace, flights remain subject to air traffic control.
Approach
BTA 1B STAR was performed. Direct BINAS is given by LIBREVILLE. Request reportin 25 DME and cleared descent level 060F for ILS Z Rwy 16. Changed tower frequence 118.7 MHz for clearing ILS.
Aerodrome included ATIS on the VHF VOLMET broadcast.
Landing
After landing 180 turns are permitted at the rwy ends lonly. Vacated via E for paring stand B1. Marshaller was over stairs.
