Cost of P-RNAV Modifications
oint Aviation Authorities

• As addressed at Terminal Airspace RNAV Workshop
  4-6 Nov03

2
Meeting P-RNAV Requirements
oint Aviation Authorities

• Large percentage of aircraft fleet operating into
  ECAC Terminal Airspace already P-RNAV compliant,
  i.e. no modifications required.
• (see presentation by R Croft - available on this
  CD-ROM)
• Practically all other aircraft modifiable to
  meet P-RNAV requirements.
• Cost of modification important consideration for
  aircraft operator.
• Benefit of P-RNAV modification? Where is the
  Cost-Benefit Analysis (CBA)?

3
Cost of Modification?
oint Aviation Authorities

• At the Workshop one presentation suggested cost
  per aircraft to be approximately 0.5 M.
• Cost very dependent on aircraft type and current
  equipage.
• Industry suggested that modifications towards
  P-RNAV compliance significantly less, and
  examples of 15 k were mentioned.
• Aircraft Operators should contact industry for
  quotations.
• Operator considerations to obtain P-RNAV approval
  dependent on the airports it operates into
  (P-RNAV procedures?) and to what extent it wants
  to take advantage of the on-board RNAV
  capabilities and available Terminal Airspace RNAV
  procedures (alternative conventional procedures).

Cost-Benefit for P-RNAV?
oint Aviation Authorities

• P-RNAV is enabler for Terminal Airspace RNAV
  operations.
• Benefits of Terminal Airspace RNAV operations are
  recognised (fuel, workload, capacity), and have
  lead to introduction of RNAV procedures in
  Terminal Airspace.
• European consistency (safety!) in Terminal
  Airspace RNAV operations and appropriate RNAV
  approval requirements P-RNAV is a major element.
• Alternative conventional (non-RNAV) Terminal
  Airspace procedures ? Not option for airports
  where RNAV procedures already in use because of
  RNAV benefits.
• Cost-Benefit Analysis is basis for RNAV
  procedures in individual ECAC Terminal Airspace
  P-RNAV is the enabling/supporting approval
  requirement.
