Private Jet Charter at St. Mary's (EGHE/ISC)

The Atlantic Outpost: Air Gateway to the Isles of Scilly

St. Mary's Airport (ISC) sits on the largest island of the Scilly archipelago, 28 miles southwest of Land's End — the most southwesterly airfield in the United Kingdom. With a 550-metre strip, ISC is one of the shortest operational runways in the British Isles accessible to any powered fixed-wing aircraft, and it defines, more than any other single factor, the operational envelope for charter arrivals. The field elevation is 116 ft above sea level on terrain exposed to Atlantic weather systems that can shift within hours; operators should monitor TAF/METAR for ISC closely, as low cloud, fog, and wind shear approaches to runway 09/27 are documented year-round.

Operational Profile

The 550-metre strip restricts inbound traffic to very light jets (Phenom 100, Citation Mustang) at best, and in practice the dominant charter type arriving at ISC is the light turboprop — the Britten-Norman Islander and Twin Otter are the workhorses of inter-island and mainland shuttle services operated by Skybus. For private charter purposes, operators sourcing a direct rotation from Farnborough or London Luton to ISC will need to position a suitably certified aircraft; most midsize and heavy jets are operationally excluded by runway length alone, regardless of MTOW. Sector planning from mainland United Kingdom airports should account for payload limitations and the short field performance data of the selected type. The only scheduled air service to the mainland is via Land's End (LEQ) and Exeter, operated by Skybus — relevant for deadhead crew positioning.

Transfers & Connections

St. Mary's is the hub of the five inhabited islands of Scilly. Onward access to Tresco, St. Agnes, Bryher, and St. Martin's is by inter-island boat (regular launches from Hugh Town quay, approximately 10–20 minutes depending on island) or inter-island Skybus helicopter when available. The town of Hugh Town is less than a mile from the airport threshold — accessible on foot or by taxi. There are no motorways, rail links, or car hire of significance; the island's road network is minimal. Passengers requiring onward travel to mainland Cornwall should note that the Scillonian III ferry from Hugh Town to Penzance operates seasonally (roughly April to October) and takes approximately 2 hours 45 minutes. Air remains the only year-round connection to the mainland.

Handling & Customs

The airport is operated by the Council of the Isles of Scilly and handling is managed through the airport's own ground operations team rather than a branded FBO. Customs clearance is listed as available on-site, which is operationally relevant for any positioning from Paris Le Bourget or other European points — confirm clearance arrangements with Border Force in advance, as H24 customs availability at an airfield of this scale and remoteness should be pre-notified rather than assumed walk-up. Operating hours are published as available year-round, but H24 operations in the strict sense should be confirmed directly with the airport authority prior to scheduling late arrivals; EGHE is not a controlled aerodrome and movements outside published hours require PPR. Fuel is available on-site (AVGAS and Jet A-1), which matters for turboprop types completing the short over-water sector from Cornwall.
