Automatic Flight Control System (AFCS)
The AFCS is approved for autopilot approaches to CAT 1 limits only.
APP mode, autopilot engaged approaches, is approved for:
* Flap 0 (minimum altitude 1000 ft AGL)
* Flap 5, 10, 15 and 35
Other autopilot limitations are as follows:
* The autopilot must be disengaged in severe icing conditions
* During autopilot operation, the pilot flying must be seated at the controls with safety and shoulder harness fastened.
* Use of VOR without associated DME is not permitted in APP mode
* After takeoff or go-around, the minimum height for autopilot engagement is 1000 feet AGL
* On approach (precision or non-precision), the autopilot must be disengaged at or above 200 ft above runway elevation
* Flight in conditions of severe atmospheric turbulence with the autopilot engaged is prohibited
* An autopilot approach must not be commenced or continued with an inoperative
engine.
NOTE
The autopilot must be disengaged at or above 1,000 ft AGL
* Autopilot and flight director only approaches are approved for glideslope angle of 2.5° to a maximum of 4 degrees
* Autopilot approaches have been demonstrated in crosswind components up to 18 knots. This is not considered limiting.
64
Baggage Compartment Fire Extinguishing
Unless the forward and aft baggage compartments are empty, the airplane must not be operated further than 1 hour flying time from a suitable airport for landing.
65
Avionics
-HOT MIC select switches on the pilot and co-pilot ARCDU must be OFF and the INT/RAD switch on the observers Audio Control Panel must be centred, when using the cockpit speakers.
-With HF Comm installed, use of the HF transmitter is prohibited when the ADF is used as the prime means of navigation or for position confirmation.
- With Integrated Standby Instrument, MS 4---432835 or MS 4---456883, installed, the airplane must not be operated further than 1 hour flying time from a suitable airport for landing.
