MEMORANDUM FOR THE RECORD
SUBJECT: Trip Report 17-19 June 1970
1. Location and Purpose of Visit
The undersigned visited Detachment G on 17 and 18 June
1970 to conduct two (2) experimental low-pressure chamber
flights using the emergency oxygen supply from one of the
two high-pressure bottles as the sole source of oxygen.
Additionally, a proposed technical manual change appears
necessary in the pilot's Handbook on Liquid Oxygen Manage-
ment when the two (2) systems feed unevenly in flight.
Discussions and a proposal have been prepared for submission
to the prime contractor.
a. The low-pressure chamber flights were completed
using one (1) high-pressure bottle as the sole source
of oxygen in two (2) separate profiles:
(1) 67,000 - 10,000' in 7 minutes unpres-
surized amount of oxygen remaining 1180 psi.

In both cases, using emergency descent rate for
the aircraft, there is adequate oxygen in either
bottle to return the crewmember to a safe
environment.
b. A proposed modification to the RQ-225 para-
chute lumbar pad has been made by Detachment G
Personal Equipment personnel F :1
This modification includes the attach-
ment of the tree-lowering device to the lower two-
thirds of the lumbar pad with hardware storage and
attachment of the lanyard to the seat kit with
velcro tape. This modification has been test flown
at Detachment G for some twenty (20) hours already
and subjective impressions of the pilots are all
optimistic.
c. Liquid 02 Aircraft Management in flight.
Two (2) proposals have been forwarded to Lockheed
Aircraft Corporation on changing the technical
data on 02 Management in the pilot's handbooks.
(1) Allow pilot privilege of turning one
system off and leaving it off until pressure
is reduced from active system whereby equal
bleed-off will again occur.
(2) Allow pilot privilege of turning
active system off once quantity gauge reaches
two (2) liters thereby allowing some one to
three hours of remaining 02 if second system
were for some reason to inadvertently fail
when turned on.
At the present time, if it appears that one LOX system
is not supplying 02 , the dual reliability may be proven
by shutting off the active system for a brief period.
However, a brief period is not adequate to allow both
systems to supply evenly and therefore the pilot
ascertains little with such a maneuver.
