Question 20-6 : Atc realises that they are unable to maintain adequate horizontal separation between 2 ifr aircraft at the same altitude what should they do ?

Atc should vector such aircraft to different flight levels to provide vertical separation

Atc must maintain adequate separation between aircraft depending on their flight rules in this case 2 ifr aircraft would not be able to maintain their own separation due to the potential for them to be in instrument meteorological conditions imc therefore atc must do this .from there it is quite a simple task of making sure that both aircraft are at different levels as this would provide adequate vertical separation when horizontal separation cannot be guaranteed exemple 140 Atc should vector such aircraft to different flight levels to provide vertical separation.

Question 20-9 : Both an aeroplane call sign ab139 and a helicopter call sign at139 are operating on the same approach frequency which of the following actions should the atc controller take in order to avoid the potential for call sign confusion ?

Request a temporary change in one of the two call signs

Learning objective 010 07 02 19 08 explain the possible request of atc to an aircraft to change its radio telephone rtf call sign .as mentioned in the learning objective above occasionally it is useful for atc to request that an aircraft changes its call sign in order to provide adequate difference with an aircraft of similar call sign or to avoid confusion when referring to any other things such as locations or procedures which might sound the same as a call sign .in this case the two aircraft have very similar callsigns only separated by 'tango' vs 'bravo' which are both similar sounding words in this case much confusion could be had when conversing with those aircraft and it is therefore best to ask one to change their call sign .it is usually up to the controller to choose a different call sign and in this case they could change 'at139' to 'helicopter 139' for instance the messages to change and then later on revert call sign from the controller would be .. change your call sign to new call sign until further advised . revert to flight plan call sign call sign at significant point exemple 152 Request a temporary change in one of the two call signs.

Note the feedback for this question was incomplete and the options we received were not correct in our view one of them is partially correct but not good enough we have therefore created our own correct answer so this is unlikely to be what you see in the exam .as this is a new question to us we would prefer to give you an idea of what they may ask rather than wait for further feedback icao annex 11 chapter 4 . 4 3 4 voice automatic terminal information service voice atis broadcasts . 4 3 4 1 voice automatic terminal information service voice atis broadcasts shall be provided at aerodromes where there is a requirement to reduce the communication load on the ats vhf air ground communication channels when provided they shall comprise a one broadcast serving arriving aircraft or . b one broadcast serving departing aircraft or . c one broadcast serving both arriving and departing aircraft or . d two broadcasts serving arriving and departing aircraft respectively at those aerodromes where the length of a broadcast serving both arriving and departing aircraft would be excessively long 4 3 4 2 a discrete vhf frequency shall whenever practicable be used for voice atis broadcasts if a discrete frequency is not available the transmission may be made on the voice channel s of the most appropriate terminal navigation aid s preferably a vor provided the range and readability are adequate and the identification of the navigation aid is sequenced with the broadcast so that the latter is not obliterated 4 3 4 3 voice atis broadcasts shall not be transmitted on the voice channel of an ils 4 3 4 4 whenever voice atis is provided the broadcast shall be continuous and repetitive . 4 3 4 5 the information contained in the current broadcast shall immediately be made known to the ats unit s concerned with the provision to aircraft of information relating to approach landing and takeoff whenever the message has not been prepared by that those unit s . 4 3 4 6 voice atis broadcasts provided at designated aerodromes for use by international air services shall be available in the english language as a minimum . 4 3 4 7 recommendation — where voice atis broadcasts are available in more than one language a discrete channel should be used for each language . 4 3 4 8 recommendation — the voice atis broadcast message should whenever practicable not exceed 30 seconds care being taken that the readability of the atis message is not impaired by the speed of the transmission or by the identification signal of a navigation aid used for transmission of atis the atis broadcast message should take into consideration human performance to go through the options in english only for departure and arrival traffic lasting one minute incorrect 4 3 4 6 above dictates the rules for languages and it is not english only they should also not exceed 30 seconds where practical as per recommendation 4 3 4 8 for arrival traffic only on the ils localiser frequency incorrect they can be broadcast to arrival and departure aircraft and never using the ils frequency for arrival traffic only preferably on the vor frequency incorrect they can be broadcast to arrival and departure aircraft on a discreet vhf requency if available but if they have to be used on a radio aid frequency then it should preferably be a vor there is a little more truth in this one than the above options but we still consider it to be incorrect for arrival and departure traffic preferably on a discreet vhf frequency correct but we made it up due to a gap in feedback so it is not what you will see in the exam exemple 228 For arriving and departing aircraft, preferably on a vor frequency.

Question 20-29 : The crew of a boeing 747 on a transoceanic flight have been assigned a speed of mach 0 76 in order to provide longitudinal separation using the mach number technique suddenly the aircraft experiences severe turbulence and has to decrease speed what does the crew have to do with regards to their ?

They must contact atc to notify them of the change as soon as possible

Note it appears that this is a scenario based version of q107432 but we do not have completely solid feedback about this question and the wording may be slightly different in the exam .learning objective 010 07 02 12 15 describe the method of the mach number technique source icao doc 4444 chapter 5 5 4 2 4 longitudinal separation minima with mach number technique based on time..icao doc 4444 pans atm .5 4 2 4 longitudinal separation minima with mach number technique based on time.5 4 2 4 1 turbojet aircraft shall adhere to the true mach number approved by atc and shall request atc approval before making any changes thereto if it is essential to make an immediate temporary change in the mach number e g due to turbulence atc shall be notified as soon as possible that such a change has been made exemple 232 They must contact atc to notify them of the change as soon as possible.

Question 20-30 : Who is in charge of traffic separation during a vfr approach ?

The pilot in command

Learning objective 010 07 02 12 03 state the difference between the type of separation provided within the various classes of airspace and the various types of flight source icao doc 4444 chapter 5 5 2 provisions for the separation of controlled traffic5 2 provisions for the separation of controlled traffic . 5 2 1 general . 5 2 1 1 vertical or horizontal separation shall be provided a between all flights in class a and b airspaces . b between ifr flights in class c d and e airspaces . c between ifr flights and vfr flights in class c airspace . d between ifr flights and special vfr flights and . e between special vfr flights when so prescribed by the appropriate ats authority except for the cases under b above in airspace classes d and e during the hours of daylight when flights have been cleared to climb or descend subject to maintaining own separation and remaining in visual meteorological conditions conditions applicable to the use of this procedure are contained in section 5 9 looking at the options above and the annex it is clear that vfr flights are not legally required to be separated from other vfr flights in any airspace therefore at all times the pilot in command of a vfr flight is responsible for their own traffic separation whilst you could argue that some scenarios would make atc also responsible for traffic separation that is only with aircraft under certain flight rules not all aircraft and certainly not in all vfr approach scenarios note we do not have much feedback for this question and whilst it is quite simple please send us any further exam feedback you might have in order to verify the question and answer thank you exemple 236 The pilot in command

Question 20-31 : Sometimes a single flight information region fir is delineated to include upper airspace within the lateral limits of a number of lower firs why is this desirable ?

To limit the amount of firs a high flying aircraft must operate in

Refer to figure .learning objective 010 07 01 03 09 explain why a uir or upper cta should be delineated to include the upper airspace within the lateral limits of a number of lower firs or ctas source icao annex 11 chapter 2 2 11 specifications for flight information regions control areas and control zonesicao annex 11 chapter 2 .2 11 4 flight information regions or control areas in the upper airspacerecommendation — where it is desirable to limit the number of flight information regions or control areas through which high flying aircraft would otherwise have to operate a flight information region or control area as appropriate should be delineated to include the upper airspace within the lateral limits of a number of lower flight information regions or control areas although the recommendation from annex 11 above is worded in quite a complex way it is not as complex as it looks as high flying aircraft are moving fast and going long distances and it is unnecessary for them to fly through many different firs or control areas upper firs uirs should be made which encompass the upper airspace of multiple lower level firs therefore upper firs are much larger than standard firs so the faster aircraft at high levels are not constantly changing from one fir to the next see the annex above france have multiple firs at lower levels but only a single 'france uir' for high levels in terms of answering this question the correct answer is stated almost exactly in the recommendation above the purpose of having larger upper firs are 'to limit the amount of firs a high flying aircraft must operate in' exemple 240 To limit the amount of firs a high-flying aircraft must operate in.

Question 20-32 : After landing when should the pilot report 'runway vacated' ?

When the entire aircraft is beyond the runway holding position

Icao doc 4444 . 7 10 3 landing and roll out manoeuvres7 10 3 4 when necessary or desirable e g due to low visibility conditions a landing or a taxiing aircraft may be instructed to report when a runway has been vacated the report shall be made when the entire aircraft is beyond the relevant runway holding position exemple 244 When the entire aircraft is beyond the runway-holding position.

Question 20-33 : Under what circumstances can separation minima be reduced between two aircraft approaching to land 1 you report that you have the other aircraft in sight.2 there is speed restriction active in the area.3 you report you can maintain visual separation with the preceding aircraft.4 both aeroplanes are ?

1 and 3

Icao document 4444 . 6 1 reduction in separation minima in the vicinity of aerodromesin addition to the circumstances mentioned in chapter 5 5 11 1 the separation minima detailed in chapter 5 5 4 1 and 5 4 2 may be reduced in the vicinity of aerodromes if a adequate separation can be provided by the aerodrome controller when each aircraft is continuously visible to this controller orb each aircraft is continuously visible to flight crews of the other aircraft concerned and the pilots thereof report that they can maintain their own separation orc in the case of one aircraft following another the flight crew of the succeeding aircraft reports that the other aircraft is in sight and separation can be maintained the succeeding aircraft should report that the other aircraft is in sight but this is not enough the pilot should also report that separation can be maintained visually under these two conditions separation minima can be reduced between the two aircraft during the approach exemple 248 1 and 3

Question 20-34 : The 'mach number technique' may be applied by atc to aircraft along the same route in order to ?

Organize safety and an orderly traffic flow

The mach number technique can be used to achieve longitudinal reference . more information on this technique can be found in icao doc 4444 '5 4 2 4 longitudinal separation minima with mach number technique based on time' and '5 4 2 5 longitudinal separation minima with mach number technique based on distance using rnav' . it is important to remember that separation is implemented primarily for safety reasons therefore any answers suggesting efficiency or reduced fuel burn as the main purposes of separation are incorrect it is essential to note that vertical separation is determined using altimeters rather than speeds as it pertains to the vertical dimension rather than the horizontal dimension exemple 252 Organize safety and an orderly traffic flow.
