Obstacles
In snow covered area's it can be very difficult to see the different ranges as the can merge with each other due the the whit color of the snow.
Obstacle departure procedures (ODP). Obstacle clearance protection provided to aircraft in instrument meteorological conditions (IMC).

OBSTACLE FREE ZONE (OFZ) - The OFZ is a three dimensional section of airspace that supports the transition of ground-to-airborne-aircraft operations (and vice versa).

Obstacle
An existing object, object of natural growth, or terrain at a fixed geographical location or which may be expected at a fixed location within a prescribed area with reference to which vertical clearance is or must be provided during ...
Obstacle Free Area (OFA): A two dimensional ground area surrounding runways, taxiways, and taxilanes which is clear of objects except for objects whose location is fixed by function.
Obstacle Clearance Minimums
Obstacle free zone (OFZ) May be used in specific region near airport. From end of runway away from MAP you have 1/2 nautical mile obstacle clearance area. This area extends in an ever widening angle to 13.5 NM.
Obstacle avoidance (OA).
Flight cues designed to avoid obstacles, such as terrain, buildings, and power lines; Compare: terrain avoidance, threat avoidance; ...
OBSTACLE FREE ZONE- The OFZ is a three dimensional volume of airspace which protects for the transition of aircraft to and from the runway.

Obstacles can be a factor during any phase of flight, including departure, enroute, or approach.
Terrain Obstacle
Point on the natural surface of the earth which is considered a potential hazard to the safe passage of aircraft in the type of operation for which the terrain and obstacle data are used.

OCH - obstacle clearance height. The lowest height above the elevation of the runway threshold or above aerodrome elevation used to establish compliance with obstacle clearance criteria in an instrument approach.
Landing over 50 ft. obstacle (ft.):

Above Ground Level (AGL) - The measurement of the height of an obstacle above the ground. A 250’ radio tower is 250’ AGL. See also MSL.
Amphibious Aircraft - a class of aircraft that can land both on land or water.
What are the terrain and obstacle elevations along the route of flight?
Depending on the place we are landing, my descision to commit to a landing is dependent on a few major factors: power available and obstacle clearance.
somehow we need to get the hydraulic oil from point A ( pump ) to point B ( motor ) and again back through a few obstacles.
Hedge-hopping: "Contour chasing" or flying low to the deck and manoeuvering to avoid obstacles on the ground.

When a certain 'deck' elevation is reached, the system automatically warns the pilot to pull the plane up to avoid the obstacle.
Under "visual flight rules", pilots are expected to see and avoid dangers along the way (obstacles, other aircraft, bad weather, etc), and to use pilotage and other means for navigating.
Our job on final is to avoid obstacles or, of they can't be avoided, use them.
Even if a sale or lease transfer could overcome legal obstacles, the ability of a private airport to operate profitably is uncertain.
These obstacles are scaring my students to the point where they do not want to fly on certain days, especially if it's hot and humid. They are even more hesitant when crosswinds and turbulence are present in the summer months.
'By attending to the progressive increase in the weight of birds, from the delicate little humming-bird up to the huge condor, we clearly discover that the addition of a few ounces, pounds, or stones, is no obstacle to the art of flying; ...
configuration provides the best downward visibility to enjoy the views provided by low and slow flying, and provides the pilot with the required visibility to be able to safely operate into unimproved areas - to be able to see and avoid obstacles.
EGPWS (Enhanced Ground Proximity Warning System) Uses aircraft inputs such as position, attitude, air speed and glide slope, which along with internal terrain, obstacles, ...
Landing distance over 50 ft obstacle: 1,160 ft
Landing distance, ground roll 625 ft ...
Since helicopters can achieve a unique aerial view and don't need to negotiate ground obstacles, they are often used in conjunction with police on the ground to report on suspects' locations and movements.
is the minimum dimension necessary for clearing obstacles and must be increased if trees exceed 50 ft. in height. This minimum dimension assumes hard ground and the possibility starting in any direction. Training fields are mile square or more.
A set of instructions to follow under Instrument Flight rules when departing an airport. They guarantee clearance from obstacles and keep all the planes flying the departure going the same way.
Did "Flood Rescue Flying" in the northern outback, with an old Gypsy Moth requiring good flying skills as landing was often on ground covered with water and obstacles producing hazards not normally encountered by pilots.
(2) A tightly-focused radio beam transmitted from the approach end of a runway indicating the minimum approach angle that will clear all obstacles; one component of an instrument landing system (ILS).
However, nothing similar occurred in the United States, where there were no such natural obstacles isolating major cities and where railroads could transport people almost as fast as an airplane, and in considerably more comfort.
more simple models, a proper setup could minimize the learning curve as much as possible. Learning how to properly align a T-Rex 450 XL helicopter could mean the difference between a successful flight and an accidental collision with an obstacle or ...
Barton has also added three sets of air planes, designed to prevent the loss of gas and ballast which has hitherto been such a serious obstacle to successful aerial navigation.
