Summary of Defect:

The Pans/Rac 4444 has changed the ICAO format for PositionReport to include Humidity and delete SupplementaryInformation.

Assigned SME:				Sub-Volume II SME

Proposed SARPs amendment:

Change the definition of PositionReport from:

PositionReport ::= SEQUENCE
	{
	positioncurrent			[0]	Position,
	timeatpositioncurrent 		[1]	Time,
	level					[2]	Level,
	fixnext				[3]	Position		OPTIONAL,
	timeetaatfixnext			[4]	Time			OPTIONAL,
	fixnextplusone			[5]	Position		OPTIONAL,
	timeetaatdestination		[6]	Time			OPTIONAL,
	remainingFuel			[7]	RemainingFuel	OPTIONAL,
	temperature				[8]	Temperature		OPTIONAL,
	winds	 				[9]	Winds			OPTIONAL,
	turbulence				[10]	Turbulence		OPTIONAL,
	icing					[11]	Icing			OPTIONAL,
	speed					[12]	Speed			OPTIONAL,
	speedground				[13]	SpeedGround		OPTIONAL,
	verticalChange			[14]	VerticalChange	OPTIONAL,
	trackAngle				[15]	Degrees		OPTIONAL,
	heading				[16]	Degrees		OPTIONAL,
	distance				[17]	Distance		OPTIONAL,
	supplementaryInformation	[18]	FreeText		OPTIONAL,
	reportedWaypointPosition	[19]	Position		OPTIONAL,
	reportedWaypointTime		[20]	Time			OPTIONAL,
	reportedWaypointLevel		[21]	Level			OPTIONAL
	} 


To:

PositionReport ::= SEQUENCE
	{
	positioncurrent			[0]	Position,
	timeatpositioncurrent 		[1]	Time,
	level					[2]	Level,
	fixnext				[3]	Position		OPTIONAL,
	timeetaatfixnext			[4]	Time			OPTIONAL,
	fixnextplusone			[5]	Position		OPTIONAL,
	timeetaatdestination		[6]	Time			OPTIONAL,
	remainingFuel			[7]	RemainingFuel	OPTIONAL,
	temperature				[8]	Temperature		OPTIONAL,
	winds	 				[9]	Winds			OPTIONAL,
	turbulence				[10]	Turbulence		OPTIONAL,
	icing					[11]	Icing			OPTIONAL,
	speed					[12]	Speed			OPTIONAL,
	speedground				[13]	SpeedGround		OPTIONAL,
	verticalChange			[14]	VerticalChange	OPTIONAL,
	trackAngle				[15]	Degrees		OPTIONAL,
	heading				[16]	Degrees		OPTIONAL,
	distance				[17]	Distance		OPTIONAL,
	humidity				[18]	Humidity		OPTIONAL,
	reportedWaypointPosition	[19]	Position		OPTIONAL,
	reportedWaypointTime		[20]	Time			OPTIONAL,
	reportedWaypointLevel		[21]	Level			OPTIONAL
	} 

Add new Humidity definition (insert between HoldClearance and InterceptCourseFrom variables):

Humidity ::= INTEGER(0..100)
	--unit = Percent Humidity, Range(0..100), resolution = 1
