L-29 Delfin Specifications

How Fast Is The L-29 Delfin?
The L-29 reaches around 407 mph, Mach 0.55. It is deliberately docile: designed so that a student with no jet experience could fly it safely from an unprepared grass or sand strip. Its reputation is for being almost impossible to spin inadvertently, a quality that made it ideal for ab initio jet training.
How Was The L-29 Delfin Developed?
Aero Vodochody developed the L-29 in the late 1950s, and it won a Warsaw Pact competitive evaluation against the Polish PZL TS-11 Iskra and Soviet Yak-30 in 1961. The prototype flew on 5 April 1959. Around 3,600 were built, and it became the standard jet trainer across the Eastern Bloc.
Has The L-29 Delfin Seen Combat?
Armed L-29s were used by Egypt against Israeli forces in the 1973 Yom Kippur War, by Nigeria during the Biafran conflict, and by Azerbaijan in the Nagorno-Karabakh conflict – with operations well outside its intended training role.
Who Operates The L-29 Delfin?
Most Warsaw Pact air forces flew the L-29, alongside Egypt, Syria, Iraq, Nigeria and Uganda. Large numbers passed into civilian ownership after the Cold War, and it remains a common warbird in Europe and North America.
L-29 Delfin FAQs
Common questions about the L-29 Delfin, its capabilities and whether civilians can fly it.
Can I book a flight in the L-29 Delfin with Jetify?
No, the L-29 Delfin is not currently bookable through Jetify. Jetify offers flights in 7 ex-military aircraft types that have been demilitarised and placed on a civil register, such as the L-39 Albatros, Hawker Hunter and MiG-15 Fagot, from 11 airfields in 7 countries.
Can I take the controls of the L-29 Delfin?
Not on a Jetify flight, because the L-29 Delfin is not currently bookable through Jetify. On the aircraft Jetify does operate, such as the L-39 Albatros, most allow you to take the controls in level flight and gentle turns once your pilot is satisfied you are comfortable.
How much does a flight in the L-29 Delfin cost?
The L-29 Delfin is not currently bookable through Jetify, so there is no price for a flight in one. Jetify flights in jets such as the L-39 Albatros start from around £2,500, $3,300 or €2,900, while the MiG-15 Fagot, Aermacchi S.211 and Lockheed T-33 start from around £2,800 ($3,800, €3,400). The Hawker Hunter, the fastest aircraft currently bookable, starts from around £6,400, $8,500 or €7,600. Every price is per person and includes ground school, flight suit, helmet and pre-flight medical screening.
Is there a weight or height limit for a jet flight instead of the L-29 Delfin?
The L-29 Delfin is not currently bookable through Jetify, but all jet flight experiences enforce strict height and weight limits set by ejection seat clearances, cockpit dimensions and harness fit. Height is typically 5ft 2in (157 cm) to 6ft 4in (193 cm), and weight is generally capped at 16 st 7 lb to 18 st 12 lb (105 kg to 120 kg) depending on the aircraft. You also need normal cardiovascular health, with no heart conditions, severe high blood pressure or recent surgery.
How much G-force would I feel on a jet flight instead of the L-29 Delfin?
The L-29 Delfin is not currently bookable through Jetify, but on a civilian jet experience aerobatic profiles typically reach four to eight positive G in sustained turns and around minus four negative G. You learn the anti-G straining manoeuvre in ground school, which keeps you conscious under load. Supersonic and high-altitude profiles are physically far easier, and what happens in the air is agreed with your pilot and can be adjusted at any point.
How far in advance should I book a jet flight instead of the L-29 Delfin?
The L-29 Delfin is not currently bookable through Jetify, but you should book a real ex-military jet experience, such as the L-39 Albatros, 2 to 4 months in advance because of limited aircraft availability, maintenance schedules and airspace clearances. For weekend slots in peak summer months, allow 6 months. Simulator experiences generally need 2 to 3 weeks’ notice for standard weekend bookings.
