[ARC5] Navigation Use of Low Freq Command Sets

[jcoward5452 at aol.com]

Wasn't Amelia Earhart's Bendix D*-*  Loop fixed and she had to rotate the airplane to obtain "fixes"?

I have no records of any WWII fighters carrying the *heavy* Bendix DF 
igs (SCR-269 and its predecessors/successors like the ARN-7), probably 
ecause of weight concerns.  Even the MN-26 was no lightweight.  The 
RN-6 came along at the end of the war, but was still pretty hefty 
ompared with one of the earlier Bendix loops like the DW or DU family 
nd their commercial brethren.  Those earlier manually steered loops 
retty much had to have a separate operator in the back seat, though 
here are certainly photos of them in single seat open cockpits, 
robably for publicity purposes.  I can't imaging trying to navigate 
ith one and still fly the plane.  The radio range receivers and the 
avy's ZB-*/ARR-1 homing system were about all that was available to a 
ighter pilot until after the war.  By 1950, aircraft engines had become 
ore powerful and capable of carrying more weight, so an automatic rig 
ike the ARN-6 was a godsend in smaller aircraft.

 In Korea (1950/1954) we had ARN-6 radio nav sets in our aircraft. In the
 fighters the loop was in the canopy behind the seat.

 But they were not used during the war except for flights to Japan. All
 flights were VFR!

 weather. No one flew then in bad weather!

 We also had 2 M-16 antiaircraft halftracks at each end of the runway. But
 they were not manned at night.

 "Bed Check Charlie" came through most evenings right at sundown!
