(b) An aircraft that is aware that the maneuverability of another aircraft is impaired shall give way to that aircraft.

‘(i) Sailplanes overtaking. A sailplane overtaking another sailplane may alter its course to the right or to the left.’

‘(2) unless stationary and otherwise adequately illuminated, all aircraft on the movement area of an aerodrome shall display lights intended to indicate the extremities of their structure, as far as practicable;’

‘(c) except for balloons, make all turns to the left, when approaching for a landing and after taking off, unless otherwise indicated, or instructed by ATC;
(d) except for balloons, land and take off into the wind unless safety, the runway configuration, or air traffic considerations determine that a different direction is preferable.’

— With regards to VFR flights planned to operate across international borders, the National regulation (point RA.4001(b)(5)) differs from the ICAO Standard in Annex 2, 3.3.1.2(e) with the addition of the underlined text, as follows:
‘any flight across international borders, unless otherwise prescribed by the States concerned.’
—With regard to VFR and IFR flights planned to operate at night, the following requirement is added to point RA.4001(b)(6) of the National regulation:
“(6) any flight planned to operate at night, if leaving the vicinity of an aerodrome”’.

‘(f) Except when necessary for take-off or landing, or except by permission from the authority, a VFR flight shall not be flown:

1. over the congested areas of cities, towns or settlements or over an open-air assembly of persons at a height less than 300 M (1 000 FT) above the highest obstacle within a radius of 600 M from the aircraft;
2. elsewhere than as specified in (1), at a height less than 150 M (500 FT) above the ground or water, or 150 M (500 FT) above the highest obstacle within a radius of 150 M (500 FT) from the aircraft

(b) the authority shall prescribe as necessary other conditions which shall be reported by all aircraft when encountered or observed.

RA.14035 Transmission of numbers in radiotelephony (a) Transmission of numbers

1. All numbers used in the transmission of aircraft call sign, headings, runway, wind direction and speed shall be transmitted by pronouncing each digit separately.
   1. Flight levels shall be transmitted by pronouncing each digit separately except for the case of flight levels in whole hundreds.
   2. The altimeter setting shall be transmitted by pronouncing each digit separately except for the case of a setting of 1 000 hPa which shall be transmitted as ‘ONE THOUSAND’.
   3. All numbers used in the transmission of transponder codes shall be transmitted by pronouncing each digit separately except that, when the transponder codes contain whole thousands only, the information shall be transmitted by pronouncing the digit in the number of thousands followed by the word ‘THOUSAND’.
2. All numbers used in transmission of other information than those described in point (a)(1) shall be transmitted by pronouncing each digit separately, except that all numbers containing whole hundreds and whole thousands shall be transmitted by pronouncing each digit in the number of hundreds or thousands followed by the word ‘HUNDRED’ or ‘THOUSAND’, as appropriate. Combinations of thousands and whole hundreds shall be transmitted by pronouncing each digit in the number of thousands followed by the word ‘THOUSAND’, followed by the number of hundreds, followed by the word ‘HUNDRED’.
3. In cases where there is a need to clarify the number transmitted as whole thousands and/or whole hundreds, the number shall be transmitted by pronouncing each digit separately.
4. When providing information regarding relative bearing to an object or to conflicting traffic in terms of the 12-hour clock, the information shall be given pronouncing the digits together such as ‘TEN O'CLOCK’ or ‘ELEVEN O'CLOCK’.
5. Numbers containing a decimal point shall be transmitted as prescribed in point (a)(1) with the decimal point in appropriate sequence indicated by the word ‘DECIMAL’.
6. All six digits of the numerical designator shall be used to identify the transmitting channel in Very High Frequency (VHF) radiotelephony communications except in the case of both the fifth and sixth digits being zeros, in which case only the first four digits shall be used.

RA.14055 Radiotelephony procedures
(b) (2) The reply to the above calls shall use the call sign of the station calling, followed by the call sign of the station answering, which shall be considered an invitation to proceed with transmission by the station calling. For transfers of communication within one ATS unit, the call sign of the ATS unit may be omitted, when so authorized by the authority.

(b) Clearances issued by air traffic control units shall provide separation:

1. between all flights in airspace Classes A and B;
2. between IFR flights in airspace Classes C, D and E;
3. between IFR flights and VFR flights in airspace Class C;
4. between IFR flights and special VFR flights;
5. between special VFR flights unless otherwise prescribed by the authority;

(e) Read-back of clearances and safety-related information

1. The flight crew shall read back to the air traffic controller safety-related parts of ATC clearances and instructions which are transmitted by voice. The following items shall always be read back:
   1. ATC route clearances;
   2. clearances and instructions to enter, land on, take off from, hold short of, cross, taxi and backtrack on any runway;
   3. runway-in-use, altimeter settings, SSR codes, newly assigned communication channels, level instructions, heading and speed instructions; and
   4. transition levels, whether issued by the controller or contained in ATIS broadcasts.

(2) Other clearances or instructions, including conditional clearances and taxi instructions, shall be read back or acknowledged in a manner to clearly indicate that they have been understood and will be complied with.

RA.5010 Special VFR in control zones
Special VFR flights may be authorized to operate within a control zone, subject to an ATC clearance. Except when permitted by the authority for helicopters in special cases such as, but not limited to, medical flights, search and rescue operations and fire-fighting, the following additional conditions shall be applied:

1. clear of cloud and with the surface in sight;
2. the flight visibility is not less than 1 500 M or, for helicopters, not less than 800 M;
3. fly at a speed of 140 KIAS or less to give adequate opportunity to observe other traffic and any obstacles in time to avoid a collision; and

1. the ground visibility is not less than 1 500 M or, for helicopters, not less than 800 M;
2. the ceiling is less than 180 M (600 FT).’
