- 1 - Introduction

The following manual is a guide to Extended Ov erwater Operations. It includes the single engine descent profile, drift down charts, regula tions and limitations with excerpts from the Saab 340 Company Flight Manual Volume 1.

Regulatory Compliance

14 CFR 121.161 Airplane limitations: Type of route.

(a) Except as provided in paragraph (e) of this section, unless approved by the Administrator in accordance with Appendix P of this part and auth orized in the certificate holder's operations specifications, no certificate holder may operate a turbine-engine-powered airplane over a route that contains a point—

(1) Farther than a flying time from an Adequa te Airport (at a one-engine-inoperative cruise speed under standard conditions in still air) of 60 minutes for a two-engine airplane or 180 minutes for a passenger-carrying airplane with more than two engines;

NOTE: Seaborne Airlines Extended Overwate r Operations are conducted within thirty (30) minutes of a suitable airport at all times. A list of suitable airports for each extended overwater flight segment will be included in the “Adequate Airports” section of the dispatch release pa ckage for the flight.

121.565 Engine inoperative: Landing; reporting.

(a) Except as provided in paragraph (b) of this section, whenever an airplane engine fails or whenever an engine is shutdown to prevent possible damage, the pilot in command must land the airplane at the nearest suitable airport, in point of time, at which a safe landing can be made.

Extended Overwater

Definition: With respect to aircraft, an operation over wa ter at a horizontal distance of more than 50 nautical miles from the nearest shoreline.

Seaborne Airlines will conduct extended overwa ter operations – partially equipped with the Saab 340 aircraft up to thirty (30) minutes flyi ng time from land. This distance will be considered to be 98 nautical miles at an expect ed single engine still air speed of 197 knots at 28,000 pounds and 9,000 feet. Th is is based upon Saab AOM data for single engine operations and represents the worst-case performanc e from an engine failure during cruise.SEABORNE AIRLINES DATE: 03-31-14 EXTENDED OVERWATER – PARTIALLY E QUIPPED PROGRAM REVISION: Original

- 2 - Operations Specifications (OpSpecs) and Deviations

Extended Overwater – Partially Equipped Operatio ns: Deviation to FAR 121.339(a) as granted in OpSpec A005

Seaborne Airlines is authorized to conduct Ex tended Overwater – Partially Equipped with the Saab 340 aircraft. Operations will be conducted as follows:

• A list of aircraft approved for Extended Ov erwater – Partially Equipped operations will be maintained in the Seaborne Airlines Dispatch Center and will show the same tail numbers approved by the FAA on Seaborne Airlines Operations Specifications.

• All Extended Overwater – Part ially Equipped flights may operate at more than 50 nautical miles from any shoreline, however the flight must remain within 98 nautical miles from any shoreline

• Authorized area of operation for this prog ram includes the airspace contained by the following coordinates:

o 20N 68W, 20N 64W, 19N 62W, 17N 60W, 14N 59W, 11N 59W, 10N 60W, the shoreline of South America from 10N west to 63W, 15N 63W, 16N 64W, 17N 68W.

o Any direct or published routes within the above airspace

• Temporary excursions outside of the op erating area may be made for weather avoidance, however the flight must return to the operating area as soon as practical.

• Extended Overwater – Partially Equipped operations are restricted to a planned cruise altitude of 11,000 feet MSL or above.

• The primary means of navigation on Exte nded Overwater – Partially Equipped routes will be GPS. In the event of a loss of GP S navigation, the flight must revert to conventional navigation. Notify ATC and Di spatch for rerouting to re-enter Class I Navigation Airspace.

• Long Range Navigation must be fully function al on any aircraft dispatched into Extended Overwater operations:

o GPS must be operable with a current navigational database.

o GPS coupling to the autopilot/ flight director (LRN selection on Captain’s EHSI and NAV mode) must be operable.

IFR Enroute Navigation Using Area Navigation Systems (OpSpec B034) (GPS Authorization)

Seaborne Airlines is authorized to conduct IFR Cl ass II navigation (including operations outside positive radar control) using approved aircraft and area navigation systems. Such operations shall be conducted only within the areas of enroute operations where this paragraph is referenced in OpSpec B050.SEABORNE AIRLINES DATE: 03-31-14 EXTENDED OVERWATER – PARTIALLY E QUIPPED PROGRAM REVISION: Original

- 3 - Authorized Areas of Enroute Operation (OpSpec B050)

Seaborne Airlines is authorized to conduct op erations in the following geographic areas:

• Caribbean Sea excluding Havana FIR

• 48 Contiguous United States

Class II Navigation Using Single Long-R ange Navigation System (OpSpec B054)

Seaborne Airlines is authorized to conduct GPS Class II Navigation using a single long range navigation system. Seaborne Ai rlines Saab 340 aircraft are authorized to use systems as listed in OpSpec B054.

The following Limitations and Provisions apply:

• Class II Navigation is only authorized in areas of operation as listed in OpSpec B050 above.

• Navigation must meet the minimum degree of accuracy required by ATC. If not specified, the error may not exceed 25 nautical miles.

• Prior to entering Class II Navigation, the aircra ft position shall be accurately fixed using ATC or land based navaids. After exiting class II navigation the position shall be fixed. Any GPS error must be logged. All GPS malf unctons shall be noted in the discrepancy section of the aircraft logbook.

• Ground based navigation facilities which are temporarily out of service may be substituted by GPS navigation.

• In the event of a loss of GPS navigation, the flight must revert to conventional navigation.

• Prior to conducting Class II navigation the Pilot-in-Command must receive a line check or conduct a leg under the supervision of a qualified Check Airman.

Extended Overwater Operations – Procedures

On Extended Overwater – Partially Equipped airc raft, there is a lifevest located under each passenger seat. There are additional lifevests lo cated in the last overhead bin. These can be used for last minute replacement of a missing or damaged lifevest. A minimum of three (3) additional lifevests must be carried.

Infant lifevests are also located in the last ov erhead bin and will be distributed by the flight attendant if an emergency situation occurs.

The total number of occupants onboard the airc raft may not exceed the number of lifevests available. In the event of missing life vest s in excess of the seating capacity, a deferred maintenance item will be opened using the NEF item for extra life vests.

All Extended Overwater – Partially Equipped flights may operate at more than 50 nautical miles from any shoreline, however the flight must rema in within 98 nautical miles from any shorelineSEABORNE AIRLINES DATE: 03-31-14 EXTENDED OVERWATER – PARTIALLY E QUIPPED PROGRAM REVISION: Original

• 20N 68W, 20N 64W, 19N 62W, 17N 60W, 14N 59W, 11N 59W, 10N 60W, the shoreline of South America from 10N west to 63W, 15N 63W, 16N 64W, 17N 68W.

• Any direct or published routes within the above airspace

Temporary excursions outside of the operatin g area may be made for weather avoidance, however the flight must return to the operating area as soon as practical.

Extended Overwater – Partially Equipped operations are restricted to a planned cruise altitude of 11,000 feet MSL or above.

The primary means of navigation on Extended Overwater – Partially Equipped routes will be GPS. In the event of a loss of GP S navigation, the flight must revert to conventional navigation. If the flight is outside of Class I airspa ce, Notify ATC and Dispatch for rerouting.

- 5 - Driftdown Procedures

In the event of an engine failure during Exte nded Overwater – Partially Equipped operations, the following flight crew procedure must be used:

• Aircraft Driftdown Procedure:

o One engine operating at MAX CONTINUO US POWER and the other inoperative with the propeller feathered.

o Flaps and Landing Gear retracted

o ECS ON above 10,000 ft. and ECS OFF below 10,000 ft.

o Speed VCLEAN +5 unless in icing conditions, then VCLEAN +15

• Advise ATC

• Divert to nearest suitable airport

• Contact Dispatch for diversion weather and single engine cruise/speed information
