2.1 PRELIMINARY OPERATIONS AND CHECKS

CAUTION:

FOR THE PILOT'S SAFETY, IT IS MANDATORY TO VERIFY THE PROPER CONDITION OF THE FLIGHT HELMET. 1 - Remove the flight helmet from its carrying bag then from its protective bag. 2 - Check the proper outer appearance of the shell (absence of deformation, cracks, damage) as well as the general cleanliness of the helmet. 3 - Check the proper condition and attachment (fastenings, gluing) of components 4 - Check the manoeuvrability of screens. 5 - Check the manoeuvrability of adjustment mechanisms of headgear assemblies.

NOTA : In case of a defect, contact the maintenance unit.

The bag will have to be stored in the area designed for the purpose. It may contain this Simplified Instruction Manual.

2.2 OPERATING PROCEDURES

CAUTION:

IN CASE OF A FALL, VIOLENT IMPACT OR CRACK, CONTACT THE MAINTENANCE UNIT FOR RECONDITIONING THE HELMET.

2.1.1 Positioning and adjustment Carry out the following operations (cf. Fig. 2 and Fig. 3): 1 - Place the black protective cap on the head. 2 - Hold the helmet on the head, tilted forward. 3 - Fit the helmet on the head by turning it with a rotational movement backward, the front part of the weather strip located approximately two fingers (index + middle finger) above the eyebrows.

30 MES HELMET HPH 700

4 - Make sure that the ears are placed correctly inside the earflaps of the equipped earshells. 5 - Fix the chincup type retention system (cf. Fig. 5), using the durable "DOT" dome fastener located on the holdfast of the strap. The durable "DOT" button ensures locking, preventing involuntary disengaging.

NOTA : Before installing the durable "DOT" dome fastener, it is necessary to adjust the length of the strap.

6 - Remove the comfort padding. 7 - Release the end of the strap from the self-holding strip located on it. 8 - Adjust the size of the strap by sliding it around the half round dee-rings, and fold back the end of the strap on the self-holding strip.

NOTA : In case a chin-strap is used (cf. Fig. 5), hook it on in place of the chincup, on the half-round dee-rings of the left attachment strap. Adjust and fix the tubular tape on the chin-strap pad with self-holding strips and on the trimmed shell by the "DOT" dome fastener.

9 - Adjust the pressure of earphones on the ears by means of the adjustment buttons of the right and left headgear, to obtain the desired acoustic comfort.

31 MES HELMET HPH 700

10 - Adjust the position of inner and outer screens using the corresponding control knobs. The interior colourless screen is manoeuvred by means of the left control knob (with the left hand); the neutral grey outer screen is manoeuvred by means of the right control knob (with the right hand).

NOTA : Each screen can adopt the high position, the low position and all intermediate positions. In the low position, the ideal position is when the screen opening is situated slightly above the nose.

11 - Connect the spiral cord plug to the aircraft’s intercom system. 12 - Adjust the microphone position.

2.1.2 Checks 1 - Check the operation of the acoustic kit by feedback on the intercom. 2 - Adjust the microphone in front of the mouth; make use of the white boundary band marked on the microphone arm. The boundary band must be straight and not twisted.

2.1.3 Use 1 - Modify, if necessary, the position of inner and outer screens, using the control buttons of the HPH 700 mechanisms, situated on the right and left side of the helmet (cf. Fig. 2 and Fig. 3). 2 - Turn on, if necessary, the lighting device using the rotary On/Off button, situated on the control unit (cf. Fig. 6).

32 MES HELMET HPH 700

2.1.4 Use of associated equipment 2.1.4.1 Breathing mask 82GK Contact the maintenance unit to install the rack assemblies (cf. Fig. 9) on the helmet. After setting up and adjusting the helmet, unfasten the retention system and install the mask bayonets in the racks, then adjust the tightening level (notch system in the rack).
