Pro feature. Available on your Jet Tracker account.
Manufacturer-published distances at sea level, ISA and reference weight. Not corrected for altitude, temperature, wind or runway condition, takeoff included. Uses the declared LDA as a proxy for effective runway length (RBAC 135.361) and the most favourable threshold in calm air (135.385(b)(1)): on the day, wind may force the shorter threshold. Destination only: does not assess the alternate aerodrome (135.387). Not a substitute for the AFM or the operator's performance analysis. Rule: RBAC 135.385 and 135.398; private flying (RBAC 91) is not factored. Runways: declared distance (LDA) from AISWEB/DECEA (2026-09-05), checkable on each aerodrome chart; where DECEA publishes no declared distance, physical length from OurAirports is used.

History
- 1979 - Lançamento em 1979, primeiro jato com winglets em produção
Certificado em setembro de 1979, foi o primeiro jato executivo em produção a usar winglets desenhados por Whitcomb (NASA), reduzindo o arrasto induzido em ~5% e estendendo o range em 200 nm sobre o GII.
- 1979First flight
- 1980FAA certification
- 1986 - Produção encerrada em 1986, substituído pelo GIV
202 unidades entregues entre 1979 e 1986. Sucedido pelo Gulfstream IV com motores Tay 611-8 (mais quietos e econômicos) e cockpit Honeywell SPZ-8400 com 6 CRTs.

Curiosities and highlights
Benefits
Plataforma certificada para missões científicas
Variantes SRA-1 e GIII-SP servem como plataforma de pesquisa atmosférica e ISR, NASA opera unidades para sensoriamento remoto e a USAF/USN mantém GIIIs em ELINT/SIGINT até hoje.
Limitations
Motores Spey ineficientes em consumo
Os Rolls-Royce Spey Mk 511-8 queimam ~380 gph em cruzeiro, 40% acima de turbofans modernos como BR710 ou Tay 611-8. Custo de combustível torna o GIII caro para operação privada hoje.
Curiosities
C-20, variante militar USAF/USN
O Pentágono adquiriu 17 unidades como C-20A/B/C/D/E para transporte de generais e missões SAM (Special Air Mission). Algumas seguem em serviço da Marinha em 2025 após mais de 35 anos.
