-----------------------------------------------------------------------

SECTION C: (Criteria Tested)

1)	Endurance (range)NM:		1450nm

2)	Take-off distance(metres):	1300m
	Landing distance(metres): 	 500m

3)	Rotation speed (Vr)(KIAS):
	a) Educated guess:	130
	b) Calculated:		117

4)	Climb: Best climb speed (KIAS/fpm):	250/2500fpm to 10000'
						300/1000fpm to 20000'

5)	Overspeed clacker sounds at(at cruise altitude)Mach number or KIAS: Mach 0.70

6)	Behavior under AP(OK/Not OK).
	a) Speed AP.		OK
	b) Altitude AP.		OK
	c) Heading AP.		See note 1
	d) NAV1 AP.		OK
	e) Back course AP.	OK
	f) Approach AP.		See Note 2
	g) Autoland		N/A

7)	Speed @ 80% N1, FL310 (Mach number or KIAS).	Mach 0.46

8)	% N1 at recommended economic cruise speed: Mach 0.63 @ FL310 = 94% N1.

9)	Stall speed (KIAS). 
	a) 100% fuel:	100/90
	b)  30% fuel:	91/83

10)	Approach speed at 30% fuel(KIAS):	118 KIAS

11)	Turns AP ON - (OK/Not OK):
	a) Level turns.		See note 1
	b) Climbing turns.	OK	
	c) Descending turns.	Tends to dive!

12)	Turns AP OFF - (OK/Not OK):
	a) Level turns.		See note 3
	b) Climbing turns.	OK
	c) Descending turns.	OK

13)	Landing speed(KIAS):
	a)  30% fuel:	118 KIAS
	b)  15% fuel:	116 KIAS

14)	Take-off with some engines out of service:
	Killed No2 engine @ 110 - less acceleration, but take-off and
	landing easy.
	With only No3 engine out - slight yaw but controllable. Take-off
	and landing easy.

SECTION D: 	NOTES/COMMENTS:

1)	At 250 KIAs (at less than 10000') a/c does not trim correctly in
	AP turns, i.e. a/c descends and then recovers altitude when the 
	turn is completed. On a test turn of 170° the a/c descended 
	(sideslipped/fell) from 7500' to 4500'.

2)	The a/c hunts the glideslope. Switch it off at 1000' and follow
	manually.

3)	When turning manually, banking at 30°, bank angle increases 
	slowly even though input is stopped.
