It is said in Kriyaa-saara, "When the plane is passing through a region of overhanging clouds, there is possibility of lightning striking and destroying the plane. As protection against that the shirah-keelaka yantra should be installed at the crest of the vimaana."
The Yantra is described in Yantra Sarvasva:
"When there is danger of lightning striking the plane, the shirah-keelaka yantra is to protect it.
Therefore it is explained below. An umbrella, of the p. 71 same size as the top of the vimaana, with ribs and metal covering should be made out of vishakantha metal. The umbrella stick, of arm's length, and peetha or stand, circular in shape, should be made out of the same metal. Then out of baka-tundila metal three wheeled keelakaas or hinges should be fixed at the front, back, and middle of the vimaana. The umbrella rod should be fixed in the middle of two keelakas.
The agnikuthaara crystal with metal cage should be fixed at the top like a crown. A three wheel switch revolving key should be fixed by the side of the pilot. Then wires made of kulishadhwamsa metal should be run from the crystal to the three wheeled revolving keelaka. In front of it shabdanaala tube with switch should be fixed. The yantra should be enclosed in a cover made of suranjikaa glass. When there is anticipatory thunder in the clouds, the glass covering cracks, and the tube of the wiring will emit sounds, and the wires will be severely shaken. When the pilot notices these signs, he should quickly set in motion the three-wheel keelee, which will revolve the umbrella with 100 linka speed. Then the crystal switch should also be turned, where-upon the crystal will also revolve with intense speed. By the speed of the revolution of the umbrella, the force of lightning will be stemmed, and the danger will be passed, leaving the vimaana and the pilot safe. That is the use of the shirah-keela yantra."
In order to tap or discover the sounds in the 8 directions of the vimaana, wired or wireless, up to 12 krosas or 27 miles, caused by birds or quadrupeds or by men, with 8 mechanisms, the shabdaakarshana yantra is prescribed to be fixed in the shoulder of the vimaana. A peetha or foot-plate four-cornered or round should be made out of bidaala metal, with a pivot in the centre.
On either side should be fitted machines which will attract any kind of sound and repeat it. With the soft leather of roruva or grinjinee bird two ball-shaped domes should be fixed. Between them in a suraghaadarsa vessel katana-drava acid should be filled and the vessel should be installed.
Above the acid vessel and between the two globes should be fixed sound spotting rod made of sound capturing ghantaara metal, fitted with a bunch of wires. It should be enclosed in a cover made of kwanaka glass. In the corner three thumb size wheeled knots should be fixed. From them to the rod fine strong wires should be connected. Enclosing the wires a karanda or p. 72 container made by kwanaadarsa glass, with small holes should be placed. A vessel made of the same glass, shaped like a drona or grain measurer, should be placed on top of it. In the east and west and north and south 4 crystals named rudantee-ratikaa should be arranged with wires.
Above it shabdaphenaka covering, with small shankus or screws fixed, should be placed. It should be covered by a covering made of kwanaadarsa glass, with 8 small holes. Wires starting from the screws and passing through the holes should reach the top of the covering. In the centre of it in an inch size hole simhaasya-danda-naala or tube should be fixed. In front of it a vaataapaakarshana chakra or wind wheel with 16 spokes with wires should be fixed. The wheels should be fixed in all 8 directions. In the simhaasya mukha naala or lion-faced tube on 8 sides revolving wheels should be fixed. 8 goblet like vessels made of pure vajeemukha metal should be fixed. Wires from the 8 holes of the covering should be placed in them. Similarly from the wind wheel wires should be connected to 8 screws in the 8 goblets on the simhaasya. Then from the 8 screws in shabdaphena, wires should be connected to the crystal in the acid vessel.
By the flow of wind the wheel turns with speedy right and left motion, and will set in motion the shabda-phena wheel. Then the wheels on the 8 screws also will turn. Then the sound detection rod made of sound-capturing ghantaara metal will be set in motion. Thereupon the two globes made of roruva-grinjinee skin will attract all sounds clearly and store inside themselves. By moving the central switch there the sounds will pass through the simhaasya tube and enter the dronaasya vessel, and make the sounds clearly audible to the hearer. The pilot will listen to the voices and direct the plane away from the vicinity of danger. Hence the shabdaakarshana yantra is prescribed.

From moss-layer to musali the ingredients should be purified, and in the said proportions should be filled in phenaakara yantra, should be baked for 3 days, and for a week the sankalana keywheel of the yantra should be turned in full speed for half a ghatika daily, when foam will be formed. The foam should be filled in shakti-sammelana yantra. Then through 6 tubes p. 75 the 6 shaktis or powers from praanana to sphotana should be injected into the foam patiently.

Then keeping it in the sun, electric power should be applied to the foam up to 85 degrees. This electric cooking should be done for 6 days. Then carefully extracting the foam from the yantra, it should be stored in the vaajeemukha metal box. That shabda-phena would be able to attract and record all kinds of sounds.

Then the product should be filled in kuttinee yantra, and churned for 3 yaamaas or 3/8 of a day, then placed in cooking vessel and rebaked for 3 days. Then it must be poured into patakriyaa yantra or cloth-forming machine and churned, so as to form an even emulsion, and that will form a fine artificial cloth. It should then be coloured with seven colours. It should be rolled round a long pole, and the pole fixed in thrimukhee-naala yantra, and equipped with a key should be installed in the shoulder of the vimaana.
When the flag-like contraption shows red indicating danger ahead the pilot should loose height and reach safety. When favourable colours are p. 76 shown, the pilot should note their significance and move the vimaana in the favourable direction.
Dishaampati Yantra: says "Kriyaasaara," "In its passage in the sky in the eight directions, the vimaana is likely to meet 15 fierce hurricanes called kowbera by the effects of the planetary forces With solar rays and unfavourable seasonal conditions. They will cause baneful skin effects on the occupants of planes and throat and lung troubles. To protect against that the Disaampti yantra is to be installed in the left shoulder of the vimaana."
The yantra is described in "Yantra Prakarana":
"In order to act as antidote to the poisonous effects of the kowbera winds, F shall describe the disaampati yantra. A peetha or foot plate, quadrangular or circular, should be made of paarvanee wood cured three times with requisite acids."
Paarvanee wood is described in "Agatatwa Laharee":
"Parvanee wood is wood which has very close joints as in sugarcane. It is red coloured, long leaved, decked with red flowers. It has small thorns, is antidote for snake-poison, is acrid in taste, and is used in driving away demons and other evil forces. It blooms in the dark half of the month."
In the centre of the peetha, a tube or pivot made of the 19th type of glass, with 9 holes, 9 switches, and 9 wires, and of arm's length, should be fixed. Eight kendras or centres should be spotted in its 8 directions. 8 naalas, pipes, or tubes, should be made 2 feet long, 6 feet high and 3 feet wide, and round in the middle. A lotus with 8 petals should be prepared and fixed on the top of the pivot.
The whole should be covered with hare-skin. Manchoolika linen should cover its mukha or entrance. The wires in the tubes should be taken to the petals above the lotus and fixed in the joints.
Manchoolikaa linen is explained in "Pata-pradeepikaa":
