Autogiro Performance Data and Capacity

Speed range - 0 to 120 m.p.h. with cruising speed of 70 m.p.h.

Flight limit - 200 mi. without refueling, about 2 1/2 hours in the air.

Useful load - 645 lbs. including one passenger. Maximum load in excess of two 170 lb. persons and necessary equipment and fuel is 30 lbs.

Landing field required - 300 feet long and reasonably smooth. Mountain meadows, pasture land, etc., suitable. [[margin]] at sea level. [[/margin]]

*Storage requirements - undetermined, but it is believed ship may be parked in open for limited time.

Steadiness - remarkably smooth in flight and while hovering even in rough air.

*Fuel and oil requirements - common grades of Aviation gasoline and oil may be used.

Photographic Equipment

Aerial maps and mosaics are made by pilots and photographers trained in that field.  Heavy equipment is required. For such use this autogiro is not practicable.

For taking oblique photographs of limited areas and particular objects where exact scale is not of major importance special cameras or cameras now available to Region One Headquarters can be used. Special cameras have list prices beginning at about $280; needed accessories would materially increase the cost of suitable equipment.  However, photographs can be taken from the interior of the ship with standard cameras if protected against high wind velocity such as is made by propellers.  Cameras taking pictures of at least size 5"x7' are preferred.

Further study should be made to determine what photographic equipment should be always available for use.  Since only one passenger can be carried it will usually be necessary for the passenger to take his own photos.  Simple equipment will be most useful.  It would be desirable to have information concerning use of this equipment available for study by those who will make flights.

General

This is a new field of operation for us all.  Some of the suggested uses must be tried to determine their practicability.  Additional uses will doubtless be suggested after further consideration and on the basis of experience gained.  During the first year the program will be largely experimental.

Much planning and preparation are essential to successful operation especially in consideration of the small useful load and the restricted radius of flights.  This limitations must be kept constantly in mind

*Check further with pilot.
