1. INTRODUCTION:
1.1 Radio communication failure procedures are prescribed in ICAO PANS-ATM Doc 4444. Based on these provisions,
following radio communication failure procedures are established to standardize the actions taken by the pilot of arriving and
departing aircraft experiencing radio communication failure at Gondia Airport, Gondia.
The purpose of this document is to establish the standard procedure to handle the event of a radio communication failure
situation at Gondia Airport to ensure safe and efficient aircraft operation.
2. GENERAL
2.1 All Transponder equipped aircraft experiencing Radio Communication Failure shall set transponder to Mode A/C code
7600 as soon as practicable.
(Note: This requirement of setting transponder to Mode A/C code 7600 in no way imposes any restriction on the pilot’s
decision to set transponder to Mode A/C code 7500 or 7700, whenever required).
2.2 Immediately after the detection of RCF, the aircraft shall attempt to establish communications with the appropriate air
traffic control unit using all other available means. In addition, the aircraft shall keep watch for any instructions that may be
issued by visual signals.
2.3 The pilot shall make blind transmission to ATC of all necessary reports and actions taken by the aircraft, e.g. descent, turn,
joining hold, leaving for approach, FAF etc., irrespective of whether partial/complete RCF has been experienced or not.
2.4 Aircraft experiencing radio communication failure shall be provided all required information necessary for the safe and
efficient conduct of flight and landing clearance without expecting acknowledgment.
3. ASSIGNED RUNWAY AND ITS AVAILABILITY FOR RCF AIRCRAFT
3.1 In case of an arriving aircraft experiencing RCF, when the Runway for landing has already been advised to and
acknowledged by the aircraft by GONDIA ATC via VHF, such runway shall be considered as the assigned runway. If an
arriving aircraft has not been advised and acknowledged any runway, Runway 04 shall be considered as an assigned runway
for such arrival.
3.2 In case of departures from Gondia airport is returning due to RCF, Runway 04 shall be considered as the assigned runway
for landing, irrespective of the runway used for departure.
3.3 Runway lights and Approach lights shall be in the ‘SWITCHED ON’ position to indicate the availability of such Runway
for aircraft experiencing RCF irrespective of visibility and Day or Night. Runway and Approach lights in the ‘SWITCHED
OFF’ position shall Indicate the non-availability of such Runway for aircraft experiencing RCF.
3.4 In case strong tailwind conditions are encountered during approach for the Runway as mentioned in para 3.1 and 3.2, the
aircraft experiencing RCF will carry out a missed approach on the runway as mentioned in para 3.1 and 3.2 and after
following the complete missed approach procedure as Published for such approach, aircraft will carry out the published
approach procedure for the opposite runway.
4. PROCEDURE FOR ARRIVALS
4.1 Arriving Aircraft - In VMC
4.1.1 continue to fly in Visual Meteorological Conditions;
4.1.2 land at the nearest suitable aerodrome;
4.1.3 report its arrival by the most expeditious means to the appropriate air traffic control unit.
4.2 Arriving Aircraft- in IMC
4.2.1 In case Radio Communication Failure takes place after establishing final approach track, aircraft may continue the
approach and land if visual or go around and carry out the missed approach procedure and join the VOR (114.2) GDA holding
procedure climbing to and maintaining 3900ft.
4.2.2 Except when descent clearance has already been received from ATC GONDIA and acknowledged, the pilot shall
continue on the ATS route maintaining filed flight plan level or level cleared and acknowledged by adjacent area control unit
i.e. VANP ACC/VECC ACC.
4.2.3 In airspace where procedural separation is being applied, maintain the last assigned speed and level, or minimum flight
altitude if higher, for a period of 20 minutes following the aircraft’s failure to report its position over a compulsory reporting
point and thereafter adjust level and speed in accordance with the filed flight plan.
4.2.4 After 20 minutes, commence descent to MHA in published hold over VOR (114.2) GDA at, or as close as possible to,
the expected approach time (EAT) last received and acknowledged; or, if no expected approach time (EAT) has been received
and acknowledged, at, or as close as possible to, the estimated time of arrival (ETA) over GDA VOR.
4.2.5 Leave “GDA” and carry out the published ILS/VOR Procedure for the runway as mentioned in para 3.1.
4.2.6 Land, if possible, within 30 minutes after the estimated time of arrival (ETA) or the last acknowledged expected
approach time (EAT), whichever is later.
5. PROCEDURE FOR DEPARTURES
5.1 DEPARTURE INTENDING TO CONTINUE TO DESTINATION
A departing aircraft experiencing radio communication failure and intending to continue to its filed flight plan destination
shall:
a) Maintain the last assigned speed and level, or minimum flight altitude if higher, for a period of 20 minutes following the
aircraft’s failure to report its position over a compulsory reporting point and thereafter adjust level and speed in accordance
with the filed flight plan.
