Me109 landing characteristics
« on: November 06, 2006, 09:54:32 AM »
Corsair was infamous for its tendency to yaw on t/o & landing and this has been modelled in AH.
Me 109 was also notorious in this respect & more 109s were lost in t/o & landing accidents than in combat, but this is not modelled in AH and the 109s don't seem to have any landing vices.

Anyone know why please?

5% of 109s were lost in takeoff/landin gaccidents. I'm pretty certain more were lost in combat...

Besides...

Bf 109 D:
"The controls, sensitive ailerons, and tail group were fully effective to the time the wheels touched the ground. So much for that."
- US Marine Corps major Al Williams. Source: Bf 109D test flight, 1938.

Me 109 E:
"Stalling speeds on the glide are 75 mph flaps up, and 61 mph flaps down. Lowering the flaps makes the ailerons feel heavier and slightly less effective, and causes a marked nose-down pitching moment, readily corrected owing to the juxtaposition of trim and flap operating wheels. If the engine is opened up to simulate a baulked landing with flaps and undercarriage down, the airplane becomes tail-heavy but can easily be held with one hand while trim is adjusted. Normal approach speed is 90 mph. At speeds above 100 mph, the pilot has the impression of diving, and below 80 mph one of sinking. At 90 mph the glide path is reasonably steep and the view fairly good. Longitudinally the airplane is markedly stable, and the elevator heavier and more responsive than is usual in single-seater fighters. These features add considerably to the ease of approach. Aileron effectiveness is adequate; the rudder is sluggish for small movements.
(Landing) This is more difficult than on the Hurricane I or Spitfire I. Owing to the high ground attitude, the airplane must be rotated through a large angle before touchdown, and this requires a fair amount of skill. If a wheel landing is done the left wing tends to drop just before touchdown, and if the ailerons are used to lift it, they snatch, causing over-correction. The brakes can be applied immediately after touchdown without fear of lifting the tail. The ground run is short, with no tendency to swing. View during hold-off and ground run is very poor, and landing at night would not be easy."
- RAF Royal Aircraft Establishment (RAE) Farnborough handling trials,Bf.109E Wn: 1304. M.B. Morgan and R. Smelt of the RAE, 1944.

Me 109 E-4:
"I established a speed of 200 kmh to enter the downwind leg, 150 at the end of the downwind, a curving final approach aiming to reduce speed to 130 kmh halfway around, 120 kmh with 30 degreed to go to the centreline and a threshold speed of 110 kmh with a dribble of power to stabilise the rate of speed decay.
Compare this with Black 6 (109 G) where I aimed to be at 200 kmh at the end of the downwind leg and not less than 165 kmh at the threshold."
- Charlie Brown, RAF Flying Instructor, test flight of restored Me 109 E-4 WN 3579. Source: Warbirds Journal issue 50.

Me 109 G:
"Once the tailwheel was firmly on the ground the brakes could be applied quite harshly, thus giving a short landing run, but care had to be taken to prevent any swing as the combination of narrow-track undercarriage and minimal forward view could easily result in directional problems."
- Eric Brown
- That is the only mention about the narrow undercarriage. Take notice that even this is just an objective note and Brown doesn't say anything else about it.

Landing battle damaged Me 109 G-2:
"I did my best landing ever. Wind blew from the right and the plane tends to veer to that direction. I hit the left brake but it was all slack. No response, but giving brief bursts of power with the engine I managed to create enough slipstream to keep the plane in straight course. Then I saw I cannot use any more power or I shall hit the tree stumps at the far end of the runway. I cut the ignition and said to myself, here we go.
By the by the plane began to veer to the right, at an ever faster rate and then the tail went up, the soil off the runway was soft. The tail went up, then the plane began to tilt to the left, the left wingtip, a 50cm piece hit the ground with a crunch and was bent. The plane was just about to nose over, but not even the prop did contact the ground, and the plane stopped there in the normal position."
- Kyösti Karhila, Finnish fighter ace. 32 victories. Source: Interview by Finnish Virtual Pilots Association.

Me 109 G-2/G-6:
- Pokela has told me that he took special care to teach the proper take-off and landing on the Me. How about the Germans, I've heard they didn't believe you could fit the planes in our small fields?
"They spoke of how the final approach speed should be 220 km/h. That would overshoot the field, we said. We landed at 180. "
- Mauno Fräntilä, Finnish fighter ace. 5 1/2 victories. Source: Interview by Finnish Virtual Pilots Association: Chief Warrant Officer Mauno Fräntilä.

Me 109 G-6:
In landing the Me was stable. The leading edge slats were quick and reliable, and they prevented the plane from lurching in slow speeds and made it possible to make "stall landings" to short fields. The problem in landings was the long nose, so the plane was partly controlled by touch in the final seconds of landing.

Me 109 G:
"-Was the Messerschmitt difficult to land?
She was not difficult to land but after touchdown you must not let her curve. In Malmi there was a 10 by 10 m spot where German night fighter pilots broke at least six of their Messerschmitts. After touchdown they had veered to the right and the plane tilted to the left until the wingtip and prop contacted the ground. Yet they had logged thousands of hours with the Messerschmitt. In the night they flew like angels and landed without any veering, but in daytime they couldn't do anything."
- Kyösti Karhila, Finnish fighter ace. 32 victories. Source: Interview by Finnish Virtual Pilots Association.

Me 109 G-6:
"The Me was stable on landings. The quickly reacing automatic wing slats  negated any swaying on slow speeds and made it possible to make "stall landings" to small fields. The problem in stall landings was the long nose, which hindered visibility forward. Because this controlling at the last stages of landing was done partly by sense of touch on the controls."
- Torsti Tallgren, Finnish post war fighter pilot. Source: Interview of Torsti Tallgren by Finnish Virtual Pilots Association.

Me 109 G-6:
Landing was slightly problematic if the approach was straight, with slight overspeed at about 180 km/h. Landing was extremely easy and pleasing when done with shallow descending turn, as then you could see easily the landing point. You had a little throttle, speed 150-160 km/h, 145 km/h at final. You controlled the descent speed with the engine and there was no problems, the feeling was the same as with Stieglitz. If I recall correctly the Me "sits down" at 140-142 km/h.
The takeoff and landing accidents were largely result from lack of experience in training. People didn't know what to do and how to do it. As a result the plane was respected too much, and pilots were too careful. The plane carried the man, and the man didn't control his plane.

Me 109 G:
"Speed at 150 knots or less, gear select to DOWN and activate the button and feel the gear come down asymmetrically. Check the mechanical indicators (ignore the electric position indicators), pitch fully fine... fuel - both boost pumps ON. If you have less than 1/4 fuel and the rear pump is not on the engine may stop in the three-point attitude. Rad flaps to full open and wings flaps to 10 degrees to 15 degrees. As the wing passes the threshold downwind - take all the power off and roll into the finals turn, cranking the flap like mad as you go. The important things is to set up a highish rate of descent, curved approach. The aircraft is reluctant to lose speed around finals so ideally you should initiate the turn quite slow at about 100-105. Slats normally deploy half way round finals but you the pilot are not aware they have come out. The ideal is to keep turning with the speed slowly bleeding, and roll out at about 10 feet at the right speed and just starting to transition to the three point attitude, the last speed I usually see is just about 90; I'm normally too busy to look after that!
The '109 is one of the most controllable aircraft that I have flown at slow speed around finals, and provided you don't get too slow is one of the easiest to three point. It just feels right ! The only problem is getting it too slow. If this happens you end up with a very high sink rate, very quickly and absolutely no ability to check or flare to round out. It literally falls out of your hands !
Once down on three points the aircraft tends to stay down - but this is when you have to be careful. The forward view has gone to hell and you cannot afford to let any sort of swing develop. The problem is that the initial detection is more difficult. The aeroplane is completely unpredictable and can diverge in either direction. There never seems to be any pattern to this. Sometimes the most immaculate three pointer will turn into a potential disaster half way through the landing roll. Other times a ropey landing will roll thraight as an arrow!"

Me 109 G:
"It was beneficial to keep the throttle a little open when landing. This made the landings softer and almost all three-point landings were successful with this technique. During landings the leading edge slats were fully open. But there was no troubles in landing even with throttle at idle."

Me 109 G:
"Takeoff and landing are known as troublesome, but in my opinion there is much more rumours around than what actually happened. There sure was some tendency to swing and it surely swerved if you didn't take into account. But I got the correct training for Messerchmitt and it helped me during my whole career. It was: "lock tailwheel, open up the throttle smoothly. When the speed increases correct any tendency to swing with your feet. Use the stick normally. Lift the tailwheel and pull plane into the sky.
Training to Me? It depended on the teacher. I got good training. First you had to know all the knobs and meters in the cockpit. Then you got the advice for takeoff and landing. Landing was easy in my opinion. In cold weather it was useful to have some RPMs during the finals and kill throttle just before flaring."

Me 109 G:
Landing: approach field with about 250 km/h speed. When turning to landing direction slow down to 200-210 and always try to land as close to the beginning of runway as possible, so you won't have problems in small fields. Gear is out, flaps out, radiator open - those operations were done at 220-240 km/h speed. Bring plane to landing direction's center and sit down on three points at 180 km/h.

I'd say that it was quite normallly controllable in landing BUT if for some reason you did something wrong it was not very forgiving. I've got an impression that the Finnish pilots preferred taking off and landing at slower speed than Germans did and though that too high speed was the reason for 109's bad reputation in landing accidents.

I recall that one Finnish rookie died because he didn't lock the tailwheel and the plane turned around in take-off.

I suppose any fighter of that era tends to get nasty if the tail wheel swings around loose...

The 109 had a rep of swinging when the wheels were on the ground. This was due to the toe-in or toe -out (can't remember which) of the wheels. If allowed to go to far, and it does not seem to be to much, a ground loop or worse could happen.

Hard surfaces, such as concrete, seemed to exagerate the problem.

While the RAF Pilots liked the Spits, they hated the view taxi'ing, and landing.    They preferred the Hurricane for these hated traits.

Combat Trim!  Turn it OFF and you will see how much more, work it is if you dont have the computer doing all the triming instantly.


Be sure to set rudder trim for takeoff:)

In the FAF service there were a bit over 50 take off/landing accidents during service of the Bf 109G. That means that roughly one third of about 160 planes suffered some kind of damage due to this. The most were repaired and some suffered take off/landing related accident more than once. Statistically the worst period was the summer 1944 when large number of new pilots were trained for the Bf 109G.

Hmmm........

I fly the 109s allot and rarely have any problems take off or landing?

I don't use auto takeoff and I don't use CT for landing.

LOL I have bent some props landing from time to time, but not just in 109s.

I think persistent handling weaknesses that result in loss of planes & pilots can reasonably be described as notorious and infamous.
