(h)  
Whenever two pilots are required for the operation, a separate means of displaying for the second pilot:

(1)  
Pressure altitude;

(2)  
Indicated airspeed;

(3)  
Vertical speed;

(4)  
Turn and slip;

(5) 
 Attitude; and

(6)  
Stabilised direction.

(i)  
A standby means of measuring and displaying attitude capable of being used from either pilot’s station for aeroplanes with an MCTOM of more than 5 700 kg or an MOPSC of more than nine that:

(1)  
is powered continuously during normal operation and, after a total failure of the normal electrical generating system, is powered from a source independent from the normal electrical generating system;

(2)  
provides reliable operation for a minimum of 30 minutes after total failure of the normal electrical generating system, taking into account other loads on the emergency power supply and operational procedures;

(3)  
operates independently of any other means of measuring and displaying attitude;

(4)  
is operative automatically after total failure of the normal electrical generating system;

(5)  
is appropriately illuminated during all phases of operation, except for aeroplanes with an MCTOM of 5 700 kg or less, already registered in a Member State on 1 April 1995 and equipped with a standby attitude indicator in the left-hand instrument panel;

(6)  
is clearly evident to the flight crew when the standby attitude indicator is being operated by emergency power; and

(7)  
where the standby attitude indicator has its own dedicated power supply, has an associated indication, either on the instrument or on the instrument panel, when this supply is in use.

(j)  
A chart holder in an easily readable position that can be illuminated for night operations.

CAT.IDE.A.135 Additional equipment for single-pilot operation under IFR 
Aeroplanes operated under IFR with a single-pilot shall be equipped with an autopilot with at least altitude hold and heading mode.

CAT.IDE.A.140 Altitude alerting system
(a)  
The following aeroplanes shall be equipped with an altitude alerting system:

(1)  
turbine propeller powered aeroplanes with an MCTOM of more than 5 700 kg or having an MOPSC of more than nine; and

(2)  
aeroplanes powered by turbo-jet engines.

(b)  
The altitude alerting system shall be capable of:

(1)  
alerting the flight crew when approaching a preselected altitude; and

(2)  
alerting the flight crew by at least an aural signal, when deviating from a preselected altitude.

(c)  
Notwithstanding (a), aeroplanes with an MCTOM of 5 700 kg or less, having an MOPSC of more than nine, first issued with an individual CofA before 1 April 1972 and already registered in a Member State on  1 April 1995 are exempted from being equipped with an altitude alerting system.
