Proposed SARPs amendment:

1/ In 2.2.1.4.2.1, change from:
PeriodicContract ::= SEQUENCE
{
reporting-interval [0] ReportingInterval DEFAULT {minutes-scale 5},

to:

PeriodicContract ::= SEQUENCE

reporting-interval [0] ReportingInterval DEFAULT minutes-scale : 5,

2/ In 2.2.1.4.2.1, change from:

AirSpeed ::= CHOICE
	{
	 mach 		[0] Mach,
	 ias  		[1] Ias,
	 mach-and-ias 	[2] SEQUENCE
		{
		 Mach,
		 Ias
		}
	}

to:
AirSpeed ::= CHOICE
	{
	 mach 		[0] Mach,
	 ias 			[1] Ias,
	 mach-and-ias 	[2] SEQUENCE
		{
		 mach Mach,
