The Suchoj Su-7 B \/ U aircraft use the KS-2 pilot&#8217;s seat (Kries\u0142o Suchowo). The Sukhoi Su-7 KB\u0141 planes have a newer KS-4 seat. The general rules for ejecting were identical to those for the PZL Lim planes.<\/p>\n<p>The recommended flight parameters for catapulting were as follows:<\/p>\n<ul>\n<li>Service ceiling 2,000 &#8211; 4,000 m.<\/li>\n<li>Speed 400 &#8211; 600 km \/ h.<\/li>\n<\/ul>\n<p>Sequence of actions for catapulting:<\/p>\n<ul>\n<li>Switch on the &quot;Danger&quot; signal.<\/li>\n<li>Report the location via the radio.<\/li>\n<li>In the helmet, lower the light filter and close the tight helmet.<\/li>\n<li>Adopt the correct position in the chair (legs on the footrest, back pressed against the backrest, head pressed against the headrest, eyes closed, gasps, clenched teeth, tense muscles).<\/li>\n<li>The mechanism was activated by levers on the armrests. Only one handle needs to be initialized.<\/li>\n<li>The canopy cover should self-disengage. (version of the Su-7 BK\u0141).<\/li>\n<li>If the cover is not rejected, drop it manually using the red handle on the starboard side. There are two overlapping mechanisms: one on the side and the other on the armrest. When both failed, the cover can be dropped with the standard (operational) opening on the port side.<\/li>\n<\/ul>\n<p>The KS-2 armchair is more modern than the KK-1 or KK-2 armchair. It provides greater comfort and more activities happen automatically, without the intervention of a remote control.<\/p>\n<p>It is possible to leave the Su-7 plane without using the KS-2 seat, but only if the seat does not work. Then you should:Reduce speed to 300-400 km \/ h.<\/p>\n<ul>\n<li>Switch the oxygen supply from the aircraft installation to the rescue system installation. To do this, pull the red pear-shaped handle.<\/li>\n<li>Use the yellow lever to open the additional locks on the seat harness.<\/li>\n<li>Turn the plane over on its back and sharply push the joystick away from you.<\/li>\n<li>For speeds&gt; 400 km \/ h, open the parachute with a delay of at least 5 seconds and at an altitude of less than 5,000 m.<\/li>\n<li>At altitudes below 3,000 m, the parachute must be opened immediately.\u00a0<\/li>\n<\/ul>\n<p><figure class=\"alignleft\">                    <img decoding=\"async\" data-src=\"https:\/\/images.polot.net\/6e254e36b2b31acc898ddc3bd1b5a09f6832fb1f\" src=\"https:\/\/images.polot.net\/6e254e36b2b31acc898ddc3bd1b5a09f6832fb1f\" alt=\"KS-2 ejection seat used in the Su-7 B plane. 2016.
