03, EUROCONTROL - Brussels

• NUP II - VHF Multi-Mode Radio development study

2
NUP II - VHF Multi-Mode Radio (VMMR) development
study

• The study will cover
• Identification of main issues
• typical VMMR radio requirements
• radio integration questions (with DSB-AM, VDL-2
  and VDL-3)
• Form, fit, function requirements (ARINC char
  compatibility)
• aircraft integration issues
• Industrial feasibility
• market value
• production aspects and cost
• installed cost analysis
• Overall feasibility analysis

Issue discussion

• VMMR radio requirements
• DSB-AM Tx - Rx
• VDL-2 Tx - Rx
• VDL-3 Tx - Rx
• VDL-4 Tx - 4 Rx
• Modular approach
• like approach MMR

• To address
• 1-transmitter, multi-receiver technology
• mode operations logic
• waveform generation
• timing / synchronisation
• channel management system optimisation

Starting point

• Initial VMMR succesfully demonstrated
• VHF-2100 designation
• new flexible design
• DSB-AM, VDL-2, VDL-3
• backward compatible with VHF-900/-920 (ARINC 750)
• Issues and questions understood
• media access and waveform (VDL-2 and TDMA VDL-3)
• function management
• RF
• modularity (function level HW and SW)
• Black label offering in 2004

• ARINC work to be completed
• aim at concurrent VDL-3, -4 characterisation

5
Aircraft integration issues

• Form, fit, function
• objective is ARINC 750 compatibility
• avoid backward fit interoperability problems
• use all existing racking, wiring and RF
  provisions
• pull and replace intention
• multi-radio channel management (redundancy,
  degradation)
• Function Co-existence
• co-site interference question needs resolution
• fundamentally no difference
• DSB-AM ? VDL-2 ? VDL-3 ? other VHF services
• VDL-3 and -4 waveform very comparable
• DSB-AM and VDL-2 , -3 integration successfully
  demonstrated

6
Industrial feasibility assessment

• Cost ? value discussion
• And
• whose cost
• whose value

• How would a VMMR
• fit the value chain?

From the value analysis

• Specific VDL- 4
• allowable installed cost analysis
• VMMR
• allowable installed cost analysis

• Production aspects
• VMMR cost to manufacture
• all mode permutations
• Overall production cost feasibility
• investment-return analysis

11
Quick example

• Assume
• total equipment cost 80 kE/aircraft (equipment)
• installation cost 100 kE/aircraft (labour and
  downtime)
• total 180 kE/aircraft (investment/aircraft)
• Assume
• fleet 20 aircraft
• If opportunity cost of capital 13, then rqd
  rate of return gt13
• gt13 over 18020 (or gt23,420)
• minimum 468 kE/year
• cost reduction or
• increased revenue
• gtgtapplication criterion

12
Summary - overall VMMR feasibility analysis

• VMMR radio, technical issues and questions
• extended multi-mode VHF radio approach
• current VMMR to include VDL-4
• VDL-4 specific questions
• typical and MOPS related
• Aircraft installation aspects
• ARINC characteristic
• VHF function and mode Co-existence
• Market value and allowable cost analysis
• airline is investor in VMMR
• only recognised airline returns count
• direct or indirect
• provides validity filter on applications

• Production cost analysis
• Investment and return assessment
• Overall feasibility analysis
