OM-A Flight procedures

Up to FL140 inclusive - 230 kts

Above FL140 to FL200 inclusive - 240 kts

Above FL200 to FL340 inclusive - 265 kts

Above FL340 - Mach 0.83

Below FL 140 - 1 min

Above FL 140 1,5 min

The key difference is that a navigation specification that includes a requirement to have an on-board performance monitoring and alerting system is referred to as an RNP specification. An RNAV specification does not have such a requirement.

• Direct to' clearances may be accepted to the IF provided that it is clear to the flight crew that the aircraft will be established on the final approach track at least 2 NM before the FAF.

• Direct to' clearance to the FAF should not be acceptable. Modifying the procedure to intercept the final approach track prior to the FAF should be acceptable for radar-vectored arrivals or otherwise only with ATC approval.

• The final approach trajectory should be intercepted no later than the FAF in order for the aircraft to be correctly established on the final approach track before starting the descent (to ensure terrain and obstacle clearance).

• Direct to' clearances to a fix that immediately precede an RF leg should not be permitted For parallel offset operations en route in RNP 4 and A-RN, transitions to and from the offset track should maintain an intercept angle of no more than 45° unless specified otherwise by ATC.

• Performance based communication

• Operator and ATS unit need approval

• With PBCS LatSM-lateral separation minima and LomgSM-longitudinal separation minima can be reduced

• RSP 180

  (180 being the maximum time in seconds for a transaction to be completed between aeroplane and ATS unit, e.g.

  position reporting)

• RCP 240

  (240 being the maximum time in seconds for a transaction to be completed between aeroplane and ATS unit, e.g after the controller issued an instruction to the crew and received their response)

• longitudinal separation is reduced from 10 to 5 min

• Lateral separation by 1/2 degrees inbetween the tracks

• Requirement for PBCS in NAT OTS:

• a. Navigation Specification RNP 4

  b. ADS-C and CPDLC equipped

  C. TCAS II

1. One inertial navigation system (INS)

1. one global navigation satellite system (GNSS); or

1. one navigation system using the inputs from one or more internal reference system or any sensor system complying with the MNPS requirement.

MNPS airspace has been replaced by NAT HLA:

• RNAV 10 applies in general. Required aircraft equipment same as for previous MNPS.

• RNAV 10 applies in general. Required aircraft equipment same as for previous MNPS RNP 4 applies to dedicated parts of the OTS (Organized Track System). Required aircraft e previous MNPS plus ADS-C/CPDLC and TCAS 7.1 (ACAS Il).

A re-planning is required if either:

• A new destination is required; or

• A significant deviation from the planned route occurs which cannot be covered with the remaining conting fuel.

Dispatch should be contacted via ACARS for support.
