1

Obstacle Departure Procedures (ODP)

A preplanned
instrument flight rule (IFR) departure procedure printed for
pilot use in textual or graphic form to provide obstruction
clearance via the least onerous route from the terminal area to
the appropriate en route structure. ODPs are recommended
for obstruction clearance and may be flown without ATC
clearance unless an alternate departure procedure (SID or
radar vector) has been specifically assigned by ATC.

2

Obstruction lights

s. Lights that can be found both on and off
an airport to identify obstructions.

3

Occluded front

Lights that can be found both on and off
an airport to identify obstructions.

4

OM

Outer Marker

5

Omission error

The failure to anticipate significant
instrument indications following attitude changes; for
example, concentrating on pitch control while forgetting
about heading or roll information, resulting in erratic control
of heading and bank.

6

Optical illusion

A misleading visual image. For the
purpose of this handbook, the term refers to the brain’s
misinterpretation of features on the ground associated
with landing, which causes a pilot to misread the spatial
relationships between the aircraft and the runway

7

Orientation

Awareness of the position of the aircraft and of oneself in relation to a specific reference point.

8

Otolith organ

An inner ear organ that detects linear acceleration and gravity orientation

9

Outer marker

A marker beacon at or near the glideslope
intercept altitude of an ILS approach. It is normally located
four to seven miles from the runway threshold on the
extended centerline of the runway.

10

Outside Air Temperature (OAT)

The measured or indicated
air temperature (IAT) corrected for compression and friction
heating. Also referred to as true air temperature.

11

Overcontrolling

The measured or indicated
air temperature (IAT) corrected for compression and friction
heating. Also referred to as true air temperature.

12

Overboost

A condition in which a reciprocating engine has
exceeded the maximum manifold pressure allowed by the
manufacturer. Can cause damage to engine components.

13

Overpower

To use more power than required for the purpose of achieving a faster rate of airspeed change.
