Question 1

Obstacle Departure Procedures (ODP)

Answer 1

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.

Question 2

Obstruction lights

Answer 2

s. Lights that can be found both on and off

an airport to identify obstructions.

Question 3

Occluded front

Answer 3

Lights that can be found both on and off

an airport to identify obstructions.

Question 4

OM

Answer 4

Outer Marker

Question 5

Omission error

Answer 5

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.

Question 6

Optical illusion

Answer 6

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

Question 7

Orientation

Answer 7

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

Question 8

Otolith organ

Answer 8

An inner ear organ that detects linear acceleration and gravity orientation

Question 9

Outer marker

Answer 9

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.

Question 10

Outside Air Temperature (OAT)

Answer 10

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

Question 11

Overcontrolling

Answer 11

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

Question 12

Overboost

Answer 12

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

Question 13

Overpower

Answer 13

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