cal transports message. (Annex 10, Vol II, 5.3.3.5.1)

COMMUNICATIONS FAILURE

GENERAL RULES

6.1.1  An aircraft operated as a controlled flight shall maintain continuous air-ground voice com-
munication watch on the appropriate communication channel of, and establish two-way communi-
cation as necessary with, the appropriate air traffic control unit, except as may be prescribed by
the appropriate ATS authority in respect of aircraft forming part of aerodrome traffic at a controlled
aerodrome. (Annex 2, 3.6.5.1)
NOTE 1: SELCAL or similar automatic signalling devices satisfy the requirement to maintain a lis-
tening watch.
NOTE 2: The requirement for an aircraft to maintain an air-ground voice communication watch
remains in affect after CPDLC has been established.
6.1.2  If a communication failure precludes compliance with 6.1.1, the aircraft shall comply with
the communication failure procedures in 6.2 below, and with such of the following procedures as
are appropriate. The aircraft shall attempt to establish communications with the appropriate air
traffic control unit using all other available means. In addition, the aircraft, when forming part of
the aerodrome traffic at a controlled aerodrome, shall keep a watch for such instructions as may
be issued by visual signals. (Annex 2, 3.6.5.2)
6.1.2.1  If in visual meteorological conditions, the aircraft shall:

a. continue to fly in visual meteorological conditions;
b. land at the nearest suitable aerodrome; and

c. report its arrival by the most expeditious means to the appropriate air traffic control unit.

(Annex 2, 3.6.5.2.1)
6.1.2.2  If in instrument meteorological conditions or when the pilot of an IFR flight considers it
inadvisable to complete the flight in accordance with 6.1.2.1 the aircraft shall:

a. unless otherwise prescribed on the basis of regional air navigation agreement, in airspace

where radar is not used in the provision of air traffic control, maintain the last assigned speed
and level, or minimum flight altitude if higher, for a period of 20 minutes following the air-
craft’s failure to report its position over a compulsory reporting point and thereafter adjust
level and speed in accordance with the filed flight plan;

b. in airspace where radar is used in the provision of air traffic control, maintain the last

assigned speed and level, or minimum flight altitude if higher, for a period of 7 minutes fol-
lowing:

1. the time the last assigned level or minimum flight altitude is reached; or
2. the time the transponder is set to Code 7600; or
3. the aircraft’s failure to report its position over a compulsory reporting point;

whichever is later, and thereafter adjust level and speed in accordance with the filed flight
plan;

c. when being radar vectored or having been directed by ATC to proceed offset using RNAV

without a specified limit, rejoin the current flight plan route no later than the next significant
point, taking into consideration the applicable minimum flight altitude;

d. proceed according to the current flight plan route to the appropriate designated navigation

aid or fix serving the destination aerodrome and, when required to ensure compliance with e.
below, hold over this aid or fix until commencement of descent;

e. commence descent from the navigation aid or fix specified in d. at, or as close as possible to,

the expected approach time last received and acknowledged; or, if no expected approach
time has been received and acknowledged, at, or as close as possible to, the estimated time
of arrival resulting from the current flight plan;

f. complete a normal instrument approach procedure as specified for the designated navigation

aid or fix; and

g. land, if possible, within thirty minutes after the estimated time of arrival specified in e. or the

last acknowledged expected approach time, whichever is later.

NOTE:

a. The provision of air traffic control service to other flights operating in the airspace concerned

will be based on the assumption that an aircraft experiencing radio failure will comply with
the rules in 6.1.2.2.

b. See also

(Annex 2, 3.6.5.2.2)

AIR-GROUND COMMUNICATIONS FAILURE

6.2.1  When an aircraft station fails to establish contact with the aeronautical station on the des-
ignated frequency, it shall attempt to establish contact on another frequency appropriate to the
route. If this attempt fails, the aircraft station shall attempt to establish communication with other
aircraft or other aeronautical stations on frequencies appropriate to the route. In addition, an air-
craft operating within a network shall monitor the appropriate VHF frequency for calls from nearby
aircraft. (Annex 10, Vol II, 5.2.2.7.1.1)

6.2

6.2.2  If the attempts specified under 6.2.1 fail, the aircraft station shall transmit its message
twice on the designated frequency(ies), preceded by the phrase 

“TRANSMITTING BLIND” and,

if necessary, include the addressee(s) for which the message is intended. (Annex 10, Vol II,
5.2.2.7.1.2)
Procedures for Air Navigation Services (PANS) Recommendation — In network operation, a
message which is transmitted blind should be transmitted twice on both primary and secondary
frequencies. Before changing frequency, the aircraft station should announce the frequency to
which it is changing. (Annex 10, Vol II, 5.2.2.7.1.2.1)

RECEIVER FAILURE

6.3.1  When an aircraft station is unable to establish communication due to receiver failure, it
shall transmit reports at the scheduled times, or positions, on the frequency in use, preceded by
the phrase 

“TRANSMITTING BLIND DUE TO RECEIVER FAILURE”. The aircraft station shall

transmit the intended message, following this by a complete repetition. During this procedure, the
aircraft shall also advise the time of its next intended transmission. (Annex 10, Vol II,
5.2.2.7.1.3.1)
6.3.2  An aircraft which is provided with air traffic control or advisory service shall, in addition to
complying with 6.3.1, transmit information regarding the intention of the pilot-in-command with
respect to the continuation of the flight of the aircraft. (Annex 10, Vol II, 5.2.2.7.1.3.2)
6.3.3  When an aircraft is unable to establish communication due to airborne equipment failure it
shall, when so equipped, select the appropriate SSR code to indicate radio failure. (Annex 10, Vol
II, 5.2.2.7.1.3.3)

PROCEDURES FOR A PILOT-IN-COMMAND AT THE SCENE OF AN

ACCIDENT

8.3.1  When a pilot-in-command observes that either another aircraft or a surface craft is in dis-
tress, the pilot shall, if possible and unless considered unreasonable or unnecessary:

a. keep the craft in distress in sight until compelled to leave the scene or advised by the rescue

coordination centre that it is no longer necessary;

b. determine the position of the craft in distress;

c. as appropriate, report to the rescue coordination centre or air traffic services unit as much of

the following information as possible.

– type of craft in distress, its identification and condition;
– its position, expressed in geographical co-ordinates or in distance and true bearing from a

distinctive landmark or from a radio navigation aid;

– time of observation expressed in hours and minutes UTC;
– number of persons observed;
– whether persons have been seen to abandon the craft in distress;
– on-scene weather conditions;
– apparent physical condition of survivors;
– apparent best ground access route to the distress site; and

d. act as instructed by the rescue co-ordination center or the air traffic services unit.

(Annex 12, 5.6.2)
8.3.2  If the first aircraft to reach the scene of an accident is not a search and rescue aircraft it
shall take charge of on-scene activities of all other aircraft subsequently arriving until the first
search and rescue aircraft reaches the scene of the accident. If, in the meantime, such aircraft is
unable to establish communication with the appropriate rescue co-ordination center or air traffic
services unit, it shall, by mutual agreement, hand over to an aircraft capable of establishing and
maintaining such communications until the arrival of the first search and rescue aircraft. (Annex
12, 5.6.2.1)
8.3.3  When it is necessary for an aircraft to direct a surface craft to the place where an aircraft
or surface craft is in distress, the aircraft shall do so by transmitting precise instructions by any
means at its disposal. If no radio communication can be established the aircraft shall use the
appropriate visual signal in paragraph 8.4. (Annex 12, 5.6.5)
8.3.4  When it is necessary for an aircraft to convey information to survivors or surface rescue
units, and two-way communication is not available, it shall, if practicable, drop communication
equipment that would enable direct contact to be established, or convey the information by drop-
ping a hard copy message. (Annex 12, 5.6.3)

8.3

8.3.5  When a ground signal has been displayed, the aircraft shall indicate whether the signal
has been understood or not by the means described in 8.3.4 or, if this is not practicable, by use of
the appropriate visual signal in paragraph 8.4. (Annex 12, 5.6.4)

SEARCH AND RESCUE SIGNALS

General

8.4.1.1  The air-to-surface and surface-to-air visual signals in this section shall, when used, have
the meaning indicated therein. They shall be used only for the purpose indicated and no other sig-
nals likely to be confused with them shall be used. (Annex 12, 5.8.1)
8.4.1.2  Upon observing any of the signals given in this section, aircraft shall take such action as
may be required by the interpretation of the signal given. (Annex 12, 5.8.2)

Signals with Surface Craft

NOTE: The following replies may be made by surface craft to the signal in 8.4.2.1:

For acknowledging receipt of signals:

a. the hoisting of the “Code pennant” (vertical red and white stripes) close up (meaning

understood);

b. the flashing of a succession of “T’s” by signal lamp in the Morse code;

c. the changing of heading to follow the aircraft.

For indicating inability to comply:

a. the hoisting of the international flag “N” (a blue and white checkered square);
b. the flashing of a succession of “N’s” in the Morse code.

8.4.2.1  The following maneuvers performed in sequence by an aircraft mean that the aircraft
wishes to direct a surface craft towards an aircraft or a surface craft in distress:

a. circling the surface craft at least once;
b. crossing the projected course of the surface craft close ahead at low altitude and:

1. rocking the wings; or
2. opening and closing the throttle; or
3. changing the propeller pitch.

NOTE: Due to high noise level on-board surface craft, the sound signals in (2) and (3)
may be less effective than the visual signal in (1) and are regarded as alternative
means of attracting attention.

c. heading in the direction in which the surface craft is to be directed.

Repetition of such maneuvers has the same meaning. (Annex 12, Appendix A, 1.1)

IN-FLIGHT FUEL MANAGEMENT

9.1  The pilot-in-command shall advise ATC of a minimum fuel state by declaring MINIMUM
FUEL when, having committed to land at a specific aerodrome, the pilot calculates that any
change to the existing clearance to that aerodrome may result in landing with less than planned
final reserve fuel.
NOTE: The declaration of MINIMUM FUEL informs ATC that all planned aerodrome options have
been reduced to a specific aerodrome of intended landing and any change to the existing clear-
ance may result in landing with less than planned final reserve fuel. This is not an emergency sit-
uation but an indication that an emergency situation is possible should any additional delay occur.
9.2  The pilot-in-command shall declare a situation of fuel emergency by broadcasting MAYDAY
MAYDAY MAYDAY FUEL, when the calculated usable fuel predicted to be available upon landing
at the nearest aerodrome where a safe landing can be made is less than the planned final reserve
fuel.
NOTE: This is an emergency and the aircraft shall be given priority over other traffic in the landing
sequence. The aircraft will be committed to a landing, as in the event of any delay or a go-around,
there may be insufficient fuel remaining for a safe landing

RESCUE AND FIRE FIGHTING SYSTEM

Airport categories for rescue and fire fighting are based on the over-all length of the longest aero-
plane normally using the airport and its maximum fuselage width as detailed in table 1.1.
Table 1.2. shows the minimum usable amounts of extinguishing agents related to the airport cate-
gories. They will be shown in the airport listings as “Fire” followed by the category number (e.g.
Fire 5).
Where fire fighting equipment is available but the category is not defined, the letter U (Uncatego-
rized) will be published (e.g. Fire U).
Where fire fighting equipment is not available, the letter N will be published.
If different category numbers are published for one airport, the lowest category number will be
shown. The higher category number with the relevant note (e.g. Fire 7 PTO, Fire 7 PPR ... etc.)
can be found within the airport information block.

The FAA fire fighting categories requires equipment similar to the ICAO fire fighting equipment
shown in the table above.

The principal extinguishing agent should be:

– a foam meeting the minimum performance level A; or
– a foam meeting the minimum performance level B; or
– a foam meeting the minimum performance level C; or
– a combination of these agents.

LOAD CLASSIFICATION OF RUNWAYS AND AIRCRAFT

ALIGNMENT CHART

At some airports the bearing strength of runway pavement is defined by Load Classification
Number (LCN)/Load Classification Group (LCG). The LCN/LCG has to be determined for a given
aircraft and compared with the specific runway LCN/LCG. Normally the LCN/LCG of an aircraft
should not be above that of the runway on which a landing is contemplated. Pre-arranged excep-
tions may be allowed by airport authorities.
The aircraft LCN/LCG can be determined as follows:

1

11

AIRPORT DATA - GENERAL

1527

LEGEND AND EXPLANATION

a. Obtain Single Isolated Wheel Load (SIWL/ESWL) for the aircraft from Aircraft Operations

Manual and locate this figure in pounds or tons, on the left scale of the chart.

b. Locate tire pressure on the scale to the right.

c. Connect the points found in 1 and 2 with a straight line. Where this line crosses the center

scale read your aircraft LCN/LCG.

d. This LCN/LCG should not be above the published runway LCN/LCG.

NOTE: LCG reformulates LCN only; there is no correlation with other methods of expressing
runway strength nor is any correlation possible.
EXAMPLE: Aircraft SIWL = 36500lbs or 16.5t

Tire pressure = 70psi or 4.9kg/cm

Aircraft LCN = 32, LCG = IV.

LEGEND AND EXPLANATION

ACN/PCN SYSTEM

a. The ICAO introduced the ACN/PCN System as a method to classify pavement bearing

strength for aircraft with an All-up Mass of more than 12500lbs (5700kg). For lighter aircraft
see item e.
DEFINITIONS:
ACN (Aircraft Classification Number) — A number expressing the relative effect of an air-
craft on a pavement for a specified standard subgrade category.
NOTE: The aircraft classification number is calculated with respect to the center of gravity
(CG) position which yields the critical loading on the critical gear. Normally the aftmost CG
appropriate to the maximum gross apron (ramp) mass is used to calculate the ACN. In
exceptional cases the forwardmost CG position may result in the nose gear loading being
more critical.
CBR (California Bearing Ratio) — The bearing ratio of soil determined by comparing the
penetration load of the soil to that of a standard material. The method covers evaluation of
the relative quality of subgrade soils but is applicable to sub-base and some base course
materials.
K — Westergaard’s modulus of subgrade reaction in MN/m3.

MN/m

3

 (Mega Newtons per cubic meter) — A measure of force in millions of Newtons per

cubic meter.
MPa (Mega Pascals) — A measure of pressure or stress in millions of Pascals.
N (Newton) — The force which, when applied to a body having a mass of 1 kilogram gives it
an acceleration of 1 meter per second squared.
Pa (Pascal) — The pressure of stress of 1 Newton per square meter.
PCN (Pavement Classification Number) — A number expressing the bearing strength of a
pavement for unrestricted operations.

b. ACN for selected aircraft types currently in use have been provided by aircraft manufacturers

or ICAO and the results are presented in tables shown on the following pages. Examples of
ACN table usage are shown below. ICAO reference documents are Annex 14, Attachment B
and Doc 9157-AN/901, Part 3.

c. PCN will be determined and reported by the appropriate authority. PCN will be qualified by

type of pavement, subgrade strength, tire pressure and calculation method information,
using the following codes:

1. The Pavement Classification Number:

The reported PCN indicates that an aircraft with an ACN equal to or less than the repor-
ted PCN can operate on the pavement subject to any limitation on the tire pressure.

2. The type of pavement:

R — Rigid

12

AIRPORT DATA - GENERAL

1530

LEGEND AND EXPLANATION

F — Flexible

3. The subgrade strength category:

A — High
B — Medium
C — Low
D — Ultra-low

4. The tire pressure category:

W — Unlimited, no pressure limit
X — High, limited to 1.75MPa (254psi)
Y — Medium, limited to 1.25MPa (181psi)
Z — Low, limited to 0.50MPa (73psi)

5. Pavement calculation method:

T — Technical evaluation
U — Using aircraft experience

EXAMPLE: Coding - PCN 80/R/B/W/T
The bearing strength of a rigid pavement, resting on a medium strength subgrade, has been
assessed by technical evaluation to be PCN 80 and there is no tire pressure limitation.

d. The appropriate authority may establish criteria to regulate the use of a pavement by aircraft

with an ACN higher than the PCN reported for that pavement.
NOTE: If the reported PCN is below the ACN for the Maximum Apron Mass, then an All-up
Mass can be calculated which is suitable to the lower reported PCN. The ACN varies linearly
between the Operating Mass Empty and the Maximum Apron Mass.

e. The bearing strength of a pavement for aircraft with an All-up Mass EQUAL TO OR LESS

than 12500lbs (5700kg) shall be made available by reporting the following information in
plain language:

1. Maximum allowable aircraft mass, and
2. Maximum allowable tire pressure.

EXAMPLE: 4000kg (8800lbs)/0.50MPa (73psi)

f. Occasional minor overloading operations are acceptable for:

Where overload operations are conducted the appropriate authority should be consulted.

1. flexible pavements by aircraft with ACN not exceeding 10 per cent above the PCN;
2. rigid or composite pavements by aircraft with ACN not exceeding 5 per cent above the

PCN;

AIRPORT DATA - GENERAL

1531

LEGEND AND EXPLANATION

3. unknown pavement structure, a 5 per cent limitation above the PCN should apply.

EXAMPLES OF ACN TABLE USAGE

EXAMPLE 1: Find the ACN of a B777-200LR with a mass of 348359kg on a rigid pavement rest-
ing on a medium strength subgrade (i.e., K = 80MN/m

3

 ). Tire pressure of the main wheels is

1.50MPa.
Solution: ACN = 82
EXAMPLE 2: An AIP contains the following information related to a runway pavement:
PCN of the pavement = 80
Determine whether the pavement can accept the following aircraft at the indicated operating
masses and tire pressures:

 

Mass (kg)

Tire Pressure (MPa)

A380-800

571000

398345

1.38

IL-96

231000

1.08

EMB ERJ 145ER

20700

0.95

Solution: ACNs of these aircraft are 67, 63, 43 and 12.9 respectively. Since the pavement in
question has a PCN of 80, it can accept all of the aircraft types cited.
EXAMPLE: Find the ACN of a B777-300 with a mass of 280400kg on a flexible pavement resting
on a medium strength subgrade (CBR-10%). The tire pressure of the main wheels is 1.48MPa.
