RADIO COMMUNICATION FAILURE PROCEDURES
1.INTRODUCTION:
1.1 Radio communication failure (RCF) procedures are prescribed in ICAO PANS-ATM DOC 4444. The objective is
to standardize the actions to be taken by the pilot of arriving and departing aircraft experiencing radio communication
failure at Mysuru airport. Based on these provisions, following radio communication failure procedures are established,
to standardize the actions to be taken by the pilot of arriving and departing aircraft at Mysuru airport.
2. GENERAL:
2.1 All Transponder equipped aircraft experiencing Radio Communication Failure shall set transponder to Mode A code
7600 as soon as practicable.
(Note: This Requirement of Setting transponder to Mode A code 7600 in no way imposes any restriction on the pilot's
decision to set transponder to Mode A code 7500 or 7700. whenever required)
2.2 Immediately after the detection of RCF, the pilot shall try to communicate to Mysuru ATS unit through the
standby frequency 124.325 MHz.
2.3 If unable to contact on standby frequency also, pilot shall try to communicate through adjacent units/stations
frequencies (HAL 127.7 MHz, VOML 127.55MHz) company frequency or by relay through other aircraft.
2.4 Unless otherwise required, the aircraft shall avoid all Restricted and Prohibited Areas.
2.5 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.
3. ASSIGNED RUNWAY AND ITS AVAILABILITY FOR RCF AIRCRAFT:
3.1 ln case of arriving aircraft, when Runway for landing has already been advised to the aircraft by ATC, such runway shall
be considered ns assigned runway. If radio communication failure occurs after the receipt of final/procedural turn or
approach clearance, the aircraft may continue its approach to land on such Runway.
3.2 In the event of arriving aircraft has not been advised of any runway for landing, Runway 27 shall be considered
as assigned runway for such arrival.
3.3 In the case of neighbouring adjacent ATC unit informs that the departing aircraft from Mysuru returning on account
of RCF and squawking 7600. the departure runway of such aircraft shall be considered as assigned runway for landing.
3.4 Mysuru ATC shall ensure approach and runway lights of the assigned runway in 'SWITCHED ON' position for
RCF aircraft irrespective of day/night/visibility/weather conditions. Approach lights in 'SWITCHED OFF' position
shall indicate that the approach should be made from the opposite end of runway. Runway and Approach lights on both sides
in ‘SWITCHED OFF' position shall indicate non- availability of Runway for aircraft experiencing RCF.
3.5 In strong tail wind conditions for assigned Runway, aircraft will carry out a missed approach on assigned runway and
after following complete missed approach procedure for such approach, will carry out the published instrument
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.
