* Three returned questionnaires from the 421st MEDEVAC Battalion in Wiesbaden, Germany.

** Two returned questionnaires from the 2-2nd Avn Regt at Camp Stanley, Korea, and two

returned questionnaires from the 1-52nd Avn Regt (CAB) at K-16, Seoul AB, Korea.

The reliance on hangaring aircraft to avoid aircraft icing is expressed by the

38th ID Avn Bde in Indiana as "we try to maximize the number of flyables stored

in the hangar during winter." That unit also moves aircraft into a hangar tempo-

rarily on a daily basis to "defrost" during periods of snow and ice, with the result

that missions are rarely cancelled due to icing. The 2-10th Avn Regiment

(Assault) at Fort Drum also makes increased use of hangar space in winter. The

unit has the organic capability to hangar 18 of its 38 UH-60 aircraft on a daily

basis. In winter, the unit hangars 18 airframes each night, plus hangars an addi-

tional four to six units in an AVIM maintenance company's hangar. On average,

16 of the 2-10th's aircraft are left outside overnight in winter, thereby contri-

buting to that unit experiencing daily groundings due to icing.

Hangaring aircraft to avoid icing or to expedite deicing is time-consuming

and labor-intensive. The 2-10th Avn Regiment (Assault) at Fort Drum pre-

positions aircraft with next-day missions in the hangar overnight to keep the air-

craft clear of ice or as part of the deicing process. The unit's standing operating

procedure dictates a seven-man team requirement to maneuver aircraft in and out
