Aircraft Pilot

General Description reference

NOTEThe C11 cuts an impressive figure parked alongside the Cherokees and Cessna's on a typical flight line.
NOTEThe construction is a mixture of steel tubing and metal skinning for the forward fuselage, with fabric covering aft of the mainplane. The wings and tail surfaces are skinned in metal and the ailerons, rudder and elevator panels revert to fabric.
NOTEThe Yak sits on a wide-tracked, inwardly-retracting undercarriage and a small, non-retracting tailwheel.
NOTEThe brakes have been modified from the standard pneumatic drums to a set of hydraulic Cleveland discs which originated in a Cessna 421.
NOTEThe Yak 11's 700 horse power, seven cylinder ASH 21 radial is hidden behind a tight fitting cowling with a cooling gill arrangement.
NOTEAccess to the cockpit is easy — simply climb up the trailing edge of the wing and push in the knob at the front bottom corner of the forward or aft canopy.
NOTECyrillic script makes everything alien to a westerner, although CAA-approved labels take care of the important bits.

Canopy and Cockpit before_start

CAUTIONDo not reach for the toggle above your head to close the canopy — all that will do is release the canopy's securing pins and allow the whole caboodle to fall off the back of the fuselage.
Close canopy using the little knob at the forward corner and make sure that it is fully home before takeoffFULLY HOME
NOTEThe canopies are allowed to be opened in flight.

Climb at 135 knots135 KT
NOTEThe VSI will show 1,600fpm at max weight and max power.

Cruise cruise

NOTEWith the throttle left wide open the C11 records 225kt TAS at 1,000 feet, for a fuel burn of 50 gallons per hour.
NOTEAt 75% power the speed and fuel burn drops to 200 knots and 33gph.
NOTEThe aeroplane becomes frugal at 140 knots, using just 16gph.

Approach and Circuit Notes approach

NOTEThe Yak C11 is typically difficult to slow down and it takes a while to get the airspeed low enough to meet the gear and flap limits of 163 and 135 knots respectively.
NOTEThe best approach to make is a curved one as the visibility over the nose is poor — non-existent from the rear seat.

Landing landing

NOTEThe landing flare needs to be positive but, once on the ground, the aeroplane stays put.
Bring stick back to prevent a noseover before any large brake pressure is appliedAFT
