Summary of Defect:

CM, ADS, FIS and ULCS ASN.1 in Edition 2 SARPs and GM do compile.

The CPDLC ASN.1 in Edition 2 does not compile:

1/ there is a space after first Le in LevelLevel.  

2/ the last Speed for dM113 is on a separate line. 

3/ although handled by most ASN.1 compilers, there is no space between the tag and the type for dM113 ([113]SpeedType...).

4/ in type LongitudeDegreesMinutesSeconds, the identifier "latonWholeMinutes" should read "latLonWholeMinutes".

5/ the type FacilityIdentification is not referenced by another ASN.1 type. It can be deleted. (actually this is a follow-up of PDR 97080010). 

6/ In section 2.4.3.2.1, in the ASN.1 definition of uplink message 152, change the field identifier from "uM152DistanceSpecifiedOffsetDirection" to "uM152DistanceSpecifiedDirection".


Assigned SME:                      SME 2, SME 3 and SM4

Proposed SARPs amendment:

1/ Replace: 

--	REACHING BLOCK [level] TO [level]			Urg(N)/Alr(L)/Resp(N)
	dM76LevelLevel						[76] Le velLevel,

by:

--	REACHING BLOCK [level] TO [level]			Urg(N)/Alr(L)/Resp(N)
	dM76LevelLevel						[76] LevelLevel,

2&3/ Replace (Point 2/ above is already fixed by 99010004).


--  [speedType] [speedType] [speedType] SPEED [speed]	Urg(N)/Alr(L)/Resp(N)
    dM113SpeedTypeSpeedTypeSpeedTypeSpeed		[113]SpeedTypeSpeedTypeSpeedType

Note: the file M001001a.asn (CM), M001001b.asn (ADS+ARF), M001001c.asn (CPDLC), M001001d.asn (FIS), M001001e.asn (ULCS) and 001001f.asn (AIDC) attached to this PDR contain the ASCII DOS text of the ASN.1 resulting from the resolution of this PDR and the deletion of the Word Perfect hidden text.

4/ Replace

latonWholeMinutes	LatLonWholeMinutes

by:

latLonWholeMinutes	LatLonWholeMinutes


5/ Delete the 5 following lines:

FacilityIdentification ::= CHOICE
{
facilityDesignation   [0] FacilityDesignation,
facilityName          [1] FacilityName
}

6/ Item 6/ above is already fixed by PDR99070001.
