ABES Oral Exam Flashcards
What does STORCALE stand for?
- Separate
- Transmit
- Other
- Request assistance
- Continue
- Alternates
- Liaise
- Emergency
What is the VMC radio failure procedure?
- Squawk 7600
- Land at nearest suitable aerodrome
- Take into account of visual aids and light signals.
- Report arrival to ATCU asap
- Adopt IMC procedure if can’t maintain VMC.
What is the IMC radio failure procedure, during an approach directed by radar?
- Squawk 7600
- Continue visually, or by means of instrument app procedures to land. If unable, carry out MAP and
continue to holding facility for an airfield with notified instrument app and carry out such an app
What is the IMC radio failure procedure, not during an approach directed by radar?
- Squawk 7600
- Maintain for 7min (from time 7600 set) current speed and last assigned level (or MSA if higher)
- Following 7min period, adjust speed and level according to current FPL and continue to landing aid serving destination aerodrome. Attempt to transmit position reports en-route
- Arrange flight to arrive over landing aid as close to ETA as possible.
- Arrange flight to arrive over landing aid at highest notified MSA (considering en-route terrain requirements)
- If following a STAR, after 7min period completed, pilot should arrange descent as close as possible to
published descent planning profile (or to arrive at IAF at minimum published level) - On reaching landing aid, begin descent at last acknowledged EAT (or at ETA if not EAT given)
o Remain in holding pattern as necessary until at the minimum published holding level.
o Rate of descent not <500ft/min.
o If “delay not determined” given, do not attempt to land, but divert - Carry out notified instrument approach and land within 30mins of EAT or ETA if possible. Look out for signals
If an aircraft is flying on a SID has RT failure, what are the pilots actions?
Follow the SID profile until end of SID, then for 7minutes remain current speed and last assigned level or MSA if higher
What is the IMC radio failure procedure for aircraft when being vectored by Radar?
(If radar vectored, or RNAV offset) continue as per ATC instructions for 3min and then proceed to rejoin
current FPL route (remaining above MSA)
Comply with notified Loss of Comms procedures for destination aerodrome
Can an aircraft operating under a SVFR clearance enter the CTR if an RTF failure is believed to have occurred?
No, must remain outside, unless RTF failure occurs after having entered the CTR already.
When might a controller suspect an emergency situation?
1- Radio contact not established when expected
2- Radio contact is lost
3- Pilot reports malfunctioning of a/c or unusual behaviour of persons on board
4- Erratic behaviour of position symbol observed
5- Aircraft is overdue at an aerodrome
6- Pilot reports aircraft is short of fuel
Other than SSR code 7600, how else might a pilot indicate they have a Complete or Partial Radio Failure?
Conducting emergency triangles:
RH = Transmitter only, LH = Complete failure
If communication is lost, or cannot be established with an aircraft, is a radio failure the only consideration?
No – always consider other emergencies.
How would a controller identify whether an aircraft’s receiver is operating, using PSR only?
Instruct the aircraft to make a turn/turns. If position indication matches instructions, resume normal service
How would a controller identify whether an aircraft’s receiver is operating, using SSR?
Use the IDENT feature to determine if pilot can hear the controllers instructions
What procedure would you expect the pilot of an IFR aircraft following the ATS route structure to follow?
IMC procedure, unless overriding safety reason compels them to use the VMC procedure
In the event that a pilot experiences a further emergency, while squawking 7600, what should they do?
Squawk 7700
At what point can normal operations be resumed following a radio failure situation?
1- When it is determined that alternative action can be taken, or resuming normal ops would not impair safety
2- If communication is re-established (in which case inform unit where RT fail was initiated)
3- When positive information received that aircraft has landed (and inform unit where RT fail was initiated)
When can levels, previously occupied by an aircraft subject to RT fail, be re-allocated?
- Following 15 minutes after the latest time the level should have been vacated.
- The lowest level in a stack should be kept clear for 30minutes (plus time for aircraft to leave vicinity).
When can normal operations be resumed after pos of RT fail aircraft not determined within 30min?
After pertinent information about it is given to operators/pilots and they take responsibility for determining if they will resume normal operations or take alternative action
When might operations normal calls be required/requested?
- Where flights receiving an ATS will operate in the area of one ATSU for a prolonged period.
- Transmissions may occur following period of 30mins RT inactivity
When an operations normal call is not made when expected, what should be your actions? (Regarding RT failure ac)
Ask: “Callsign, confirm operations normal?”, and following successive unsuccessful attempts, initiate overdue action
What does ASSISTS stand for?
- Acknowledge
- Separate
- Silence
- Inform
- Support
- Time
- Squawk
What is the definition of the Uncertainty Phase?
A situation where in UNCERTAINTY exists as to the safety of an aircraft and its occupants
What is the definition of the Alert Phase?
A situation wherein APPREHENSION exists as to the safety of an aircraft and its occupants
What is the definition of the Distress Phase?
A situation wherein there is REASONABLE CERTAINTY that an aircraft and its occupants are threatened by grave and
imminent danger or require immediate assistance
What needs to be coordinated with ATC regarding fuel dumping?
1- Route to be flown.
2- Level to be used.
3- Estimated duration of fuel dump.
4- Frequency to be monitored while fuel dumping.
What is the definition of a strayed aircraft?
An aircraft which has deviated significantly from its intended track, or which reports it is lost
What is the definition of an unidentified aircraft?
An a/c which has been observed/reported to be operating in a given area but whose identity hasn’t been established
What action shall be taken by ATC regarding a strayed aircraft?
1- Attempt to established two-way communication
