Bailing out and parachute control
Type of improvement: Gameplay / Education / Control
Explanation of proposals: This is proposed that the bailing procedure gets more complicated and saving life with a parachute becomes more difficult than just single key stroke. First of all, for better understanding I would like to remind the procedures for bailing out.
A. Small aircraft - crew members do not have to move any lateral distance to get to the exit door/latch:
1. Disconnect radio/intercom cables and oxygen masks hose.
2. Open cockpit canopy.
4. Unlatch seat belts
5. Leave the cockpit by use of muscles or g-force (positive or negative as required - normal/inverted fligth).
6. Pull the ripcord when clear of airplane to avoid entanglement, but having height above ground in mind, too. Also, in certain cases long freefall with much delayed opening of parachute canopy would be advised.
B. Big aircraft - crew members have to move a lateral distance to get to the exit door/latch and some of them may have their chest pack parachutes detached from their harnesses (which are worn all the times) and stowed in special boxes near their stations. Some of them may not have their seatbelts fasten during certain activities:
1. Disconnect radio/intercom cables and oxygen masks hose.
2. Unlatch seat belts if used.
3. Reach for chest pack parachute and clip it on your harness - in certain cases (and sometimes before point 2)
4. Move to emergency exit latch - in certain cases
5. Open the exit door/release cockpit canopy (in certain cases before point 2)
6. Leave the cabin by use of muscles or negative g-force (or positive depending on situation - anyway acting in the proper direction to assist with leaving)
7. Pull the ripcord when clear of airplane to avoid entanglement, but having height above ground in mind, too. Also, in certain case long freefall with much delayed opening of parachute canopy would be advised.
Forgetting something (like forgeting to clip a chest pack to the harness) or doing all but in wrong sequnce may have bad consequences.
Each action should take a certain, reasonable minimum time.
High g-force, side force, centrifugal force (what vaues? yet to be proposed) may make moving to emergency exit/latch and exiting the aircraft impossible.
Opening parachute too close to the airframe may result in entaglement or burning of parachute canopy and/or lines, when the airframe is on fire.
Speed in freefall, accelarations, decellerations, trajectory and time/distance of parachute extraction and inflation, should be as close as possible to real thing.
Airspeed limit for parachute deployment should be introduced, so in case of leaving airplane in high speed dive, a freefall of at least 3-5 seconds, depending on aircraft speed on leaving, is required to reduce airspeed of parachutist to speed below the limit. If it is exceeded, the canopy or suspension lines should fail during canopy inflation. 250 km/h is proposed.
Once the parachute is open, an aviatior has some limited control over the descent. He/she can pull down risers to perform slip in one of four directions. For example pulling two front risers approx 50 cm down will cause vertical speed to increase by approx. only 0.1 m/s (e.g. from 5.0 m/s to 5.1 m/s) but it will also cause the parachute to move forward with lateral speed of approx 1 m/s (in reference to air, not ground, of course). Pulling down 2 left side risers will cause slip to the left.
It is also possible to perform deep slip when 2-3 suspenssion lines are pulled down much more, like 2-3 meters, causing significant deformation of canopy, which should extend not more than to the apex. In such deep slip the descent rate may increase even twice. Very useful when wind is blowing an aviator towards enemy lines. Also aviator can twist the risers to turn his body under the parachute so he is facing in the direction of lateral travel (useful for landing, to avoid hitting something hard with back of head). Both slips and twisting the risers requires physical strenght and should be used wisely, to avoid running out of energy before reaching the ground. After landing pulling on lower suspennsion lines would cause canopy to collapse and avoid dragging.
Therefore it is proposed that there is more than just 1 or 2 keys for the whole bailing out, freefall and parachute ride. The following keys could be considered:
Key #1. Disconnect radio/intercom cables/oxygen hose
Key #2 Clip chect pack parachute to the harness (unless backpack or seatpack is used)
Key #3. Move to emergency exit door (only in case of bigger airplanes requiring such step). High g-force, side force, centrifugal force may make it impossible.
Key #4. Unlatch seat belts
Key #5. Use muscles to exit the cockpit/cabin (not always needed, when g-force can help, negative or positive depending on situation).
Key #6. Pull the ripcord in the best possible moment, considering circumstance, but not later than 2-3 seconds before hitting ground.
Key #7,8,9,10 To perform normal slips in one of 4 directions.
Key #11 To perform a deep slip
Key #12,13 To twist risers to turn body under parachute (round full canopy can not be turned) towards direction of travel (in reference to ground)
Key #14 to pull lower susspension lines to avoid dragging.
Certain aircraft controls keys, buttons, axies can be used for some of the above purposes, when aviator has already left the cockpit/cabin (for example joystick primary 2 axies for normal slips, and rudder for twisting risers).
Keys #1 and #4 could be tied together.
Keys #3 and #5 could be tied together.
Of course, the whole jump should be observed from first person perspective.
Benefits: More realism, better immersion, better uderstanding of real bailing out procedures, as well as demands, dangers and risks associated with bailing out. Educational aspect include also learning the need for frequent bail out procedure drill rehearsal - exactly as in real life.
Having peformed approx 100 jumps with conventional round canopy parachutes in the begining of my skydiving career many years ago, I would be happy to assist and provide advice if needed on that subject.
