Explication (français)

Dispatch selon le MEL Air Inuit AILO-0903 (texte extrait du PDF dans l’app). Catégorie(s) de réparation : C — 10 jours calendaires ; A — délai indiqué dans les remarques de l’item. 14 condition(s) de relief extraite(s) du tableau officiel (installé / requis / remarques).

Procédure équipage — (O) / (M) / placard

1. Confirmer l’item, la catégorie et le nombre requis dans le MEL officiel (lien PDF).

2. Appliquer les procédures (O) et/ou (M) du MEL avant dispatch — texte officiel ci-dessous.

3. Placard (texte MEL) :

Apply sticker on or adjacent to control and/or display.

4. Journey log / other instructions (texte MEL) :

Print the following information in the journey log sheet. FLIGHT MANAGEMENT COMPUTER SYSTEM (COMPONENT) (FUNCTION) (NAV DATA) INOP

5. Respecter toutes les restrictions du MEL — ne pas en inventer.

(O) OPERATIONS PROCEDURES — texte MEL :

Dispatch with inoperative or expired Navigation Database: • Enter flight plan into FMCS (waypoints, etc.) using standard FMCS procedures. • Cross check FMCS waypoints using current flight crew navigation charts. • Manually tune and identify approach navigation radios. OPERATIONS NOTE In order to conduct polar operations, the HDG REF switch must be installed, and one FMC, one CDU, and GPS-L must be operational for dispatch. On airplanes with dual FMC’s installed and one FMC inoperative, operating with the FMC Source Select Switch selected to the operational FMC (BOTH ON L or BOTH ON R) is required to accomplish all Flight Management Computing tasks. Primary means RNP RNAV operations up to a 10 minute duration can be accomplished with a single FMC. Long range navigation requires single FMC with dual MCDUs with Alternate Navigation capability.

(M) MAINTENANCE PROCEDURES — texte MEL (maintenance ; l’équipage vérifie que c’est fait) :

None required.

(M#) MAINTENANCE PROCEDURES — personnel maintenance obligatoire — texte MEL :

34-36-02-02-02 Computer NOTE: An inoperative FMC may be deactivated by opening and collaring the FMCS CMPTR No. 1 or No. 2 circuit breaker on the P6 or P18 panel, as appropriate. Deactivate the autothrottle system per AMM Task 22-31-00-040-801. MAINTENANCE NOTE An inoperative FMC may be deactivated by opening and collaring the FMCS CMPTR No. 1 or No. 2 circuit breaker on the P6 or P18 panel, as appropriate.
