8.4 Combat Turn
• BEFORE entry into this manoeuvre, study the surrounding airspace to make sure that no
other aircraft are flying in proximity of your aircraft, that you will remain clear of cloud,
congested areas and that sufficient altitude is available should the manoeuvre is not
successful. Select the necessary ground reference points for completing the manoeuvre.
Special attention should be paid to the space above the aircraft
• SET the rpm to 70%, provide a full boost and at a low speed decay increase the IAS to
280km/h
• Then by a SMOOTH pulling of the yoke backwards, approach the nose-over to the
horizon line
• Using a fast and coordinated moving of the yoke backwards and to the combat turn's side
at a simultaneous motion of the rudder pedals in the same direction, perform the aircraft
transition to spiral climb with the initial bank of 15° to 20° and acceleration of 3.5-4
• A rate of entry into chandelle must be such that after a 130° turn the aircraft has a bank
and a 50° climb angle, and with a further turn this position should be held
• On having made a 150° turn (30° before recovery reference point) by simultaneous
moving of the yoke and rudder pedals towards the side opposite the turn, recover the
aircraft so that the airspeed indicator reading at recovery is at least 150km/h,
simultaneously, by a slight deflecting of the yoke forwards, provide a nose-over position
relative to the horizon just the same as at the horizontal flight
8.5 Diving
• BEFORE entry into this manoeuvre, study the surrounding airspace to make sure that no
other aircraft are flying in proximity of your aircraft, that you will remain clear of cloud,
congested areas and that sufficient altitude is available should the manoeuvre is not
successful. Select the necessary ground reference points for completing the manoeuvre.
Special attention should be paid to the space under the aircraft
• Perform entry into the dive from horizontal flight or from a turn at an IAS of 150km/h
allowing NO NEGATIVE load factors
• Diving can be performed with the throttle open or closed with an IAS of NOT more than
300km/h at the recovery termination
• While diving, observe the engine temperature not allowing the temperature of the
cylinder heads to drop BELOW 120°C
• The aircraft is to be recovered from a dive by a smooth pulling of the yoke backward
• Warning, the pilot will experience considerable g-loads with a fast pulling of the yoke at
high diving speeds
• To PREVENT the IAS exceeding 300km/h during the dive recovery, the dive recovery
should be started with 40°-50° descent angles with an IAS not more than 280km/h
8.6 Steep Climb/Zoom
• BEFORE entry into this manoeuvre, study the surrounding airspace to make sure that no
other aircraft are flying in proximity of your aircraft, that you will remain clear of cloud,
congested areas and that sufficient altitude is available should the manoeuvre is not
