109-E3 FM feedback.

[Sternjaeger II]

the way they conducted tests and the conclusions they reach are simply ridiculous. Among the nonsense:

1) time of climb chart: the discrepancy between the registered time and the German published time is ridiculous. Almost 2 mins difference at ft20k is enough to raise questions on it.

"Owing to cooling difficulties the radiators were open up to 13,000 ft. and then gradually closed up to 26,000 ft. This may account for the discrepancy between the measured times to height and those published in Germany. The top level speed agreed well with the published figure. Absolute ceiling. – 32.000 ft."

oh really?


2) The Me109 was fully loaded but they don't say either the mk or loadout of the hurricane and spitfire.

3) "As the speed is increased the ailerons gradually become heavier, but response remains excellent. They are at their best between 150 m.p.h. and 200 m.p.h., and are described as " an ideal control " over this speed range. Above 200 m.p.h. they start becoming unpleasantly heavy, and at 300 m.p.h. are far too heavy for comfortable manoeuvring. Between 300 m.p.h. and 400 m.p.h. the ailerons are described as " solid " ; at 400 m.p.h. a pilot, exerting all his strength, cannot apply more than about fifth-aileron.

More detailed aileron tests (measurement of stick forces and time to bank) were-made, and are described in section 5.2. These tests showed that, although the Me.109 ailerons felt much heavier
than those of the Spitfire at speeds between 300 m.p.h. and 400 m.p.h., the aircraft could be made to bank at about the same rate as the Spitfire at these high airspeeds. The more " solid " feel of
the Me.109 ailerons at high airspeeds is attributed to smaller stick travel (+/- 4 in. compared with +/- 8 in. on the Spitfire)., fairly rigid control circuit, and partly to the awkward seating position of the pilot. The matter is more fully discussed in section 5.2."

so what they're saying is that yes, the controls are hard but deliver the same performance of the Spitfire, with the added bonus that unlike the Hurri and Spit, the Me109 does no "snaking"...

4) " After these turns the Me.109 was put into a steep dive at full throttle with the airscrew pitch coarsened to keep the r.p.m. down. It was found that both the Hurricanes and the Spitfires could keep up with the Me.109 in the dive" you don't say

I could go on, but I reckon this is enough..
