History
Specifications

The Messerschmitt Bf 109, the most mass-produced fighter of Hitler's Germany, appeared in 1934 in response to the Luftwaffe's request for the latest single-engine monoplane fighter. The prototype's first flight took place on May 28, 1935, and from 1936 to 1942, 6 models were built — from the Bf 109 A "Anton" to the Bf 109 G "Gustav."

In the second half of the war, the tension in the skies continued to increase, leading to a sharp rise in aircraft losses. In 1944, the Luftwaffe was fighting at the limit of its capabilities and switched to air defense. The aircraft industry was reorganized to increase production of fighter aircraft. To coordinate all activities related to the serial production of fighters, a "Fighter Headquarters" was created in March 1944 at the Ministry of Aviation, which quickly established cooperation between assembly plants and component suppliers, using the harshest repressive and administrative measures.

Another step taken to increase production was the standardization of numerous modifications and variants of the Bf 109 G-6, which made it difficult to schedule deliveries of components. Another attempt to solve this problem was the serial Bf 109 G-14, which went into production in May 1944, but it was not possible to turn it into a universal fighter without modifications.

The main difference from its predecessor was the use of the Erla-type cockpit canopy and oversized landing gear wheels. The DB 605AM or DB 605AS (high-altitude version of the Bf 109 G-14/AS) engine with a corresponding oil radiator and the MW 50 water-methanol boost system were fitted as standard, giving the DB 605AM fighter a top speed at low altitudes of 30-45 km/h higher than in unboosted mode. Together with the new engine modification, a specially selected propeller with wider blades was used on the Bf 109 G-14. More common was the installation of a radio direction finder and a FuG 16ZY radio with an additional antenna under the left wing. Early aircraft had a standard "short" tail section of the fuselage, while later ones were equipped with a new, taller tail of increased area, both in metal and, in the later period, in a wooden version. Some were produced with the MG 151/20 cannon. Later G-14s were produced with a shortened antenna mast, and in the last series the mast was abandoned and the antenna was mounted directly on the fuselage surface.

A night modification of the Bf 109 G-14/N was produced - the commander's aircraft of this type was equipped with a FuG 350 "Naxos" direction finder. As a rule, these aircraft were equipped with a FuG 16ZY radio for guidance and navigation in the dark.

The Bf 109G-14 could be used with the following set of conversion kits:

Factory:
  • U4 - mounting of the MK 108 30 mm cannon in the nose;
Field:
  • R1 - removable ETC 500/IH under-fuselage bomb rack;
  • R3 - rack for a 300-liter drop tank;
  • R6 - two suspended gunpods with 20 mm MG 151/20 cannons.

In July 1944 three fighter units, JG 4, JG 76, and JG 77, were equipped with Bf 109 G-14s. At the end of the war, it turned out that almost all fighter units flying Messerschmitts had some number of G-14s. Various variants of the G-14 were produced until February 1945, and a total of about 5,500 Bf 109 G-14 and Bf 109 G-14/AS were built.

Operation features:
- The aircraft has a wide automatization of the engine systems, in fact, to control speed it is only necessary to use the throttle lever. There is no need to manually set engine revolutions and mixture or supercharger gear in normal flight.
- The aircraft is equipped with MW-50 water-methanol mixture injection system that prevents the engine detonation in the emergency power mode. It engages automatically when the throttle is set to maximum, there is enough mixture for 25-30 minutes. However, the engine can work up to 10 minutes at this mode, wait for another 10 minutes at the combat mode before engaging the emergency mode again. Attention: running the engine at the emergency mode without the water-methanol mixture or at altitudes higher than 6 km is forbidden! A pilot can check the system using the injection pressure indicator on the left: its normal pressure is 0.6...0.7 atm, stop using it if the pressure is lower than 0.4 atm and switch the engine to combat mode.
- In addition to full-automatic mode there is a special manual control mode for the radiator shutters, which can be used in specific situations.
- To reduce swinging during taxiing due to prop-wash the prop pitch control should be switched to manual mode and pitch should be reduced to minimum.
- The aircraft has no flight-control trimmers. Airplane is equipped with bendable trim tabs that can be set pre-flight by ground personnel.
- The aircraft has a manually controlled horizontal stabilizer. It should be set to +1° before takeoff and to -4°...-5° before landing. Also, it may be used to trim the flight stick during the flight. In a deep dive the stabilizer should be set so that the pilot must push the flight stick forward to maintain the dive angle.
- The aircraft has automatic wing slats. They deploy when the high angle of attack increases which makes pre-stall softer.
- The aircraft has a manual mechanical system for retracting the landing flaps, for this reason it is necessary to extend landing flaps well before final approach. Markers on the left-wing flap indicate how far the flaps are extended. The flaps can be extended to any angle up to 40°.
- The aircraft has a manual tailwheel lock. Wheel should be locked when taxiing straight for a long distance and before takeoff and landing.
- The aircraft has independent left and right hydraulic wheel brake controls. To apply either brake push the upper part of the rudder pedal.
- The aircraft has a fuel gauge which shows total fuel remaining. Also, it has an emergency fuel warning light (80 liters).
- The design of the cockpit canopy does not allow it to be opened during flight. The canopy should be closed before takeoff to prevent damage. The canopy has an emergency release system for bailouts.
- The control system for the bomb rack only allows to drop bombs one by one.
- The gunsight has a sliding sun-filter.
