AMC1 NCO.OP.101(a) Altimeter check and settings - Regulation (EU)
2022/012/R
PRE-FLIGHT ALTIMETER CHECK
A serviceable altimeter indicates the elevation of the point selected, plus the height of the
altimeter above this point, within a tolerance of ± 60 ft.
If the altimeter does not indicate the reference elevation or height exactly but is within
the specified tolerances, no adjustment of this indication should be made at any stage of a
flight. Also, any error which is within tolerance on the ground should be ignored by the
pilot during flight.
If no altimeter setting is available at the aerodrome or operating site of departure, the
altimeter should be set using the elevation of the aerodrome or operating site, and the
altimeter setting should be verified on first contact with an ATS unit.

provided that:
- the role, according to the reasonable expectation of the operator, will enhance
the safety of the flight or achieve an operational objective of the flight;
- the person, according to the reasonable expectation of the operator, is capable
of fulfilling the role;
- the person has been briefed on the role as a crew member and informed that they
are crew, not a passenger; and
- the person agrees to the role as a crew member.
- Crew members are not considered to be passengers.
- Crew members may be required, by specific provisions of this Regulation and other
Implementing Rules, to hold licences, ratings or other personnel certificates to fulfil
certain roles such as instructor, examiner or flight engineer in certain circumstances.
NCO.OP.185 In-flight fuel/energy management - Regulation (EU)
2021/1296
- The pilot-in-command shall monitor the amount of usable fuel/energy remaining on board to
ensure that it is protected and not less than the fuel/energy that is required to proceed to
an aerodrome or operating site where a safe landing can be made.
- The pilot-in-command of a controlled flight shall advise air traffic control (ATC) of a
‘minimum fuel/energy’ state by declaring ‘MINIMUM FUEL’ when the pilot-in-command has:
- committed to land at a specific aerodrome or operating site; and
- calculated that any change to the existing clearance to that aerodrome or operating
site, or other air traffic delays, may result in landing with less than the planned
final reserve fuel/energy.
- The pilot-in-command of a controlled flight shall declare a situation of ‘fuel/energy
emergency’ by broadcasting ‘MAYDAY MAYDAY MAYDAY FUEL’ when the usable fuel/energy estimated
to be available upon landing at the nearest aerodrome or operating site where a safe landing
can be made is less than the planned final reserve fuel/energy.
GM1 NCO.OP.185(b)&(c) In-flight fuel/energy management - Decision
2022/005/R
‘MINIMUM FUEL’ DECLARATION
- The pilot-in-command may consider reporting the remaining fuel/energy endurance after a
‘MINIMUM FUEL’ or ‘MAYDAY MAYDAY MAYDAY FUEL’ declaration.
Note: For Part-NCO operators, the FRF/energy varies; therefore, the ATC may not be aware
of the amount of the remaining fuel/energy endurance.
- The ‘MINIMUM FUEL’ declaration informs the ATC that all planned landing options have
been reduced to a specific aerodrome or operating site of intended landing, and that for
helicopters, no other landing site is available. It also informs the ATC that any change
to the existing clearance may result in landing with less than the planned FRF/energy.
This is not an emergency situation but an indication that an emergency situation is
possible, should any additional delay occur.
The pilot should not expect any form of priority handling as a result of a ‘MINIMUM
FUEL’ declaration. However, the ATC should advise the flight crew of any additional
expected delays, as well as coordinate with other ATC units when transferring the
control of the aircraft, to ensure that the other ATC units are aware of the flight’s
fuel/energy state.
- The requirement for declaring ‘MINIMUM FUEL’ and ‘MAYDAY MAYDAY MAYDAY FUEL’ applies
only to controlled flights; however, these declarations may also be made during
uncontrolled flights if the pilot-in-command considers this advisable.
NCO.OP.190 Use of supplemental oxygen - Regulation (EU) 2016/1119
- The pilot-in-command shall ensure that all flight crew members engaged in performing duties
essential to the safe operation of an aircraft in flight use supplemental oxygen
continuously whenever he/she determines that at the altitude of the intended flight the lack
of oxygen might result in impairment of the faculties of crew members, and shall ensure that
supplemental oxygen is available to passengers when lack of oxygen might harmfully affect
passengers.
- In any other case when the pilot-in-command cannot determine how the lack of oxygen might
affect all occupants on board, he/she shall ensure that:
- all crew members engaged in performing duties essential to the safe operation of an
aircraft in flight use supplemental oxygen for any period in excess of 30 minutes
when
the pressure altitude in the passenger compartment will be between 10 000 ft and 13
000 ft; and
- all occupants use supplemental oxygen for any period that the pressure altitude in
the passenger compartment will be above 13 000 ft.
AMC1 NCO.OP.190(a) Use of supplemental oxygen - Decision
2016/018/R
DETERMINATION OF SUPPLEMENTAL OXYGEN NEED
When determining the need for supplemental oxygen carriage and use, the pilot-in-command
should:
- in the preflight phase:
- be aware of hypoxia conditions and associated risks;
- consider the following objective conditions for the intended flight:
- altitude;
- duration of the flight; and
- any other relevant operational conditions.
- consider individual conditions of flight crew members and passengers in relation
to:
- altitude of the place of residence;
- smoking;
- experience in flights at high altitudes;
- actual medical conditions and medications;
- age
- disabilities; and
- any other relevant factor that may be detected, or reported by the
person; and
- when relevant, ensure that all flight crew members and passengers are briefed on
hypoxia conditions and symptoms, as well as on the usage of supplemental oxygen
equipment.
- during flight:
- monitor for early symptoms of hypoxia conditions; and
- if detecting early symptoms of hypoxia conditions:
- consider to return to a safe altitude, and
- ensure that supplemental oxygen is used, if available.
GM1 NCO.OP.190 Use of supplemental oxygen - Decision 2016/018/R
GENERAL
- The responsibility of the pilot-in-command for safety of all persons on board, as
required by NCO.GEN.105(a)(1), includes the determination of need for supplemental
oxygen use.
- The altitudes above which NCO.OP.190(b) requires oxygen to be available and used are
applicable to those cases when the pilot-in-command cannot determine the need for
supplemental oxygen. However, if the pilot-in-command is able to make this
determination, he/she may elect in the interest of safety to require oxygen also for
operations at or below such altitudes.
- The pilot-in-command should be aware that flying below altitudes mentioned in
NCO.OP.190(b) does not provide absolute protection against hypoxia symptoms, should
individual conditions and aptitudes be prevalent.
GM2 NCO.OP.190 Use of supplemental oxygen - Decision 2016/018/R
DETERMINATION OF OXYGEN NEED — BEFORE FLIGHT
Detailed information and guidance on hypoxia conditions and symptoms, content of the briefing
on hypoxia and assessment of individual conditions may be found in the EASA leaflet
‘Hypoxia’.
DETERMINATION OF OXYGEN NEED — IN FLIGHT
Several methods for monitoring hypoxia early symptoms may be used and some methods may be
aided by personal equipment, such as finger-mounted pulse oximeters. Detailed information
and guidance on entering hypoxia conditions, on hypoxia symptoms early detection, and on use
of personal equipment such as finger-mounted pulse oximeters or equivalent may be found in
the EASA leaflet ‘Hypoxia’.

2021/2237
Before commencing an approach to land, the pilot-in-command shall be satisfied that:
- according to the information available, the meteorological conditions at the aerodrome or
the operating site, and the condition of the runway intended to be used will not prevent a
safe approach, landing, or missed approach; and
- the selected aerodrome operating minima are consistent with all of the following:
- the operative ground equipment;
- the operative aircraft systems;
- the aircraft performance, and
- flight crew qualifications.
AMC1 NCO.OP.205 Approach and landing conditions – aeroplanes - Decision
2021/005/R
LANDING DISTANCE ASSESSMENT
- The in-flight landing distance assessment should be based on the latest available
weather report and, if available, runway condition report (RCR).
- The assessment should be initially carried out when weather report and RCR, if
available, are obtained, usually around top of descent. If the planned duration of the
flight does not allow to carry out the assessment in non-critical phases of flight, the
assessment should be carried out before departure.
- When meteorological conditions may lead to a degradation of the runway surface
condition, the assessment should include consideration of how much deterioration in
runway surface friction characteristics may be tolerated, so that a quick decision can
be made prior to landing.
- Whenever the RCR is in use and the runway braking action encountered during the landing
roll is not as good as reported by the aerodrome operator in the RCR, the
pilot-in-command should notify the air traffic services (ATS) by means of a special
air-report (AIREP) as soon as practicable.
GM1 NCO.OP.205 Approach and landing conditions — aeroplanes - Decision
2021/005/R
RUNWAY CONDITION REPORT (RCR)
When the aerodrome reports the runway conditions by means of an RCR, the information
contained therein includes a runway condition code (RWYCC). The determination of the RWYCC
is based on the use of the runway condition assessment matrix (RCAM). The RCAM correlates
the RWYCC with the contaminants present on the runway and the braking action.
A detailed description of the RCR format and content, the RWYCC and the RCAM may be found in
Annex V (Part-ADR.OPS) to Regulation (EU) No 139/2014, in Regulation (EU) 2017/373 and in
Regulation (EU) No 923/2012 (SERA). Further guidance may be found in the following
documents:
- ICAO Doc 9981 ‘PANS Aerodromes’;
- ICAO Doc 4444 ‘PANS ATM’;
- ICAO Doc 10064 ‘Aeroplane Performance Manual’; and
- ICAO Circular 355 ‘Assessment, Measurement and Reporting of Runway Surface
Conditions’.
NCO.OP.206 Approach and landing conditions — helicopters - Regulation (EU)
2021/2237
Before commencing an approach to land, the pilot-in-command shall be satisfied that:
- according to the information available, the meteorological conditions at the aerodrome or
the operating site and the condition of the final approach and take-off area (FATO) intended
to be used will not prevent a safe approach, landing or missed approach; an
- the selected aerodrome operating minima are consistent with all of the following:
- the operative ground equipment;
- the operative aircraft systems;
- the aircraft performance;
- flight crew qualifications.

FATO SUITABILITY
The in-flight determination of the FATO suitability should be based on the latest available
meteorological report.
NCO.OP.210 Commencement and continuation of approach — aeroplanes and helicopters - Regulation
(EU) 2021/2237
- If the controlling RVR for the runway to be used for landing is less than 550 m (or any
lower value established in accordance with an approval under SPA.LVO), then an instrument
approach operation shall not be continued:
- past a point at which the aircraft is 1 000 ft above the aerodrome elevation; or
- into the final approach segment if the DH or MDH is higher than 1 000 ft.
- If the required visual reference is not established, a missed approach shall be executed at
or before the DA/H or the MDA/H.
- If the required visual reference is not maintained after DA/H or MDA/H, a go-around shall be
executed promptly.

helicopters - Decision 2022/012/R
VISUAL REFERENCES
- For a straight-in approach, at DH or MDH, at least one of the visual references
specified below should be distinctly visible and identifiable to the pilot:
- elements of the approach lighting system;
- the threshold;
- the threshold markings;
- the threshold lights;
- the threshold identification lights;
- the visual glide path indicator;
- the touchdown zone (TDZ) or TDZ markings;
- the TDZ lights;
- FATO/runway edge lights;
- for helicopter PinS approaches, the identification beacon light and visual
ground reference;
- for helicopter PinS approaches, the identifiable elements of the environment
defined on the instrument chart; or
- for helicopter PinS approaches with instructions to ‘proceed VFR’, sufficient
visual cues to determine that the conditions for VFR are met.
- For a circling approach, the required visual reference is the runway environment.
AMC2 NCO.OP.210 Commencement and continuation of approach — aeroplanes and
helicopters - Decision 2022/012/R
RVR MINIMA FOR CONTINUED APPROACH
- The controlling RVR should be the touchdown RVR.
- If the touchdown RVR is not reported, then the midpoint RVR should be the controlling
RVR.
- If neither the touchdown RVR nor the midpoint RVR is reported, then NCO.OP.210(a) is not
applicable.
GM1 NCO.OP.210 Commencement and continuation of approach — aeroplanes and
helicopters - Decision 2022/012/R
APPLICATION OF RVR REPORTS
- There is no prohibition on the commencement of an approach based on reported RVR. The
restriction in NCO.OP.210 applies only if the RVR is reported and applies to the
continuation of the approach past a point where the aircraft is 1 000 ft above the
aerodrome elevation or into the final approach segment (FAS) as applicable.
- If a deterioration in the RVR is reported once the aircraft is below 1 000 ft on in the
FAS, as applicable, then there is no requirement for the approach to be discontinued. In
this situation, the normal visual reference requirements would apply at the DA/H.
- Where additional RVR information is provided (e.g. midpoint and stop end), this is
advisory; such information may be useful to the pilot in order to determine whether
there will be sufficient visual reference to control the aircraft during roll-out and
taxi.
- If the RVR is less than the RVR calculated in accordance with AMC3 NCO.OP.110, a
go-around is likely to be necessary since visual reference may not be established at the
DH, or at the MDH at a point where a stable approach to landing in the TDZ remains
possible. Similarly, in the absence of an RVR report, the reported visibility may
indicate that a go-around is likely. The pilot‑in‑command should consider available
options, based on a thorough assessment of risk, such as diverting to an alternate,
before commencing the approach.
NCO.OP.220 Airborne collision avoidance system (ACAS II) - Regulation (EU)
2016/1199
When ACAS II is used, pilot-in-command shall apply the appropriate operational procedures and be
adequately trained.
