Seats And Safety Harnesses - Pipistrel Sinus 503 Flight And Maintenance Manual

www.pipistrel.si
Sinus ultralight motorglider ships with two different types of standard instrument panels: the con-
ventional panel and the glass panel (difference seen on previous page). The glass panel utilizes the
power of Brauniger multifunction instrument to screen both flight and engine parameters. Both
panels share a magnetic compass, a side-slip indicator, 12 V chargette, cockpit heating lever and an
eventual propeller pitch knob.
The optional XL instrument panel has enough room for all the extra instruments and there is a map
pocket on either side of the cockpit for storage.
All aircraft from mid-2003 onwards are serially equipped with acustic alarms to help you recognise
and avoid dangerous flight parameters such as: stall speed, exceeding VNE, low/high oil pressure etc.
The volume of these acustic alarms can be adjusted by turning a knob on the instrument panel.
Notes on Brauniger Alpha MFD multifunction instrument
• The new version of Brauniger AlphaMFD multifunction instrument (V315) also features
an acoustic vario-meter and an acoustic VNE alarm.
• Certain Brauniger AlphaMFD instalations require the multifunction instrument to be
switched ON seperately from the aircraft's master switch.
• Always make sure the instrument is switched OFF when you leave the aircraft not to
discharge its internal battery.
Undercarriage
The undercarriage is a taildragger type with two main, brake equipped, wheels mounted on struts
and a free-spinning or rudder-guided tail wheel.

Seats and safety harnesses

Seats have no stiff internal structure and do not offer different settings. All Sinus ultralight motor-
gliders ship with H type safety harness attached to the fuselage at three mounting points.
Pitot-Static lining
The pitot tube is attached to the bottom side of the right-hand wing. Pitot lines made of composite
materials lead through the inside of the wing all the way to the instrument panel.
Air brakes (spoilers)
Spoilers are most commonly used to increase drag and steepen the final approach.
During takeoff, climb and cruise spoilers MUST be retracted and locked (handle in cockpit in full up
position). To unlock and extend spoilers, pull the handle downwards.
