(4444) What is the procedure for setting the altimeter when assigned an IFR altitude of 18,000 feet or higher on a direct flight off airways?
Set the altimeter to the current reported setting for climb out and 29.92′′ Hg upon reaching 18,000 feet
. better vertical separation of aircraft.
How do I choose an IFR altitude?
For IFR flight, the regulations simply state that you
need to fly at the altitude assigned by the air traffic controller
, but if you’re flying IFR in uncontrolled airspace, you need to stay at even thousands for westerly headings and odd thousands when flying in easterly directions.
What is IFR altitude?
The minimum vectoring altitude [or minimum IFR altitude (MIA)] in each sector provides
1,000 feet above the highest obstacle in non-mountainous areas
and 2,000 feet above the highest obstacle in designated mountainous areas.
How often should you obtain an altimeter setting during flight?
The basic rule still applies to pilots flying below 180 on an IFR flight plan: Set the
altimeter setting when you get ATIS
. During your flight, when you are still too far out to get ATIS, change it when ATC gives you a new altimeter, which they will along your flight.
What cruising altitude is appropriate for VFR on top?
VFR‐ON‐TOP CRUISING LEVELS FOR YOUR DIRECTION OF FLIGHT ARE:
more than 3,000 feet above the surface to FL 180: ODD/EVEN ALTITUDES/FLIGHT LEVELS PLUS FIVE HUNDRED
FEET.
How is cruising altitude determined?
Answer: The flight operator files a requested altitude, usually done by the flight dispatcher, based on performance and economics. Air traffic control reviews the flight plan, checking for conflicts. They issue the cruising altitude based
on the requested flight plan and other traffic
.
Does an altimeter measure?
An altimeter is a device that
measures altitude
—a location’s distance above sea level. Most altimeters are barometric, meaning they measure altitude by calculating the location’s air pressure.
Why a minimum flight altitude is assigned?
The minimum vectoring altitude in each sector provides
1000 ft above the highest obstruction in non-mountainous areas
and 2000 ft above the highest obstacle in designated mountainous areas. The MVA is the lowest altitude that meets obstacle clearance requirements in the airspace specified.
What altitude would be required by the VFR cruising altitude rule for an airplane on a magnetic course of 240?
What altitude would be required by the VFR cruising altitude rule for an airplane on a magnetic course of 240°? C. Whenever you are
in level cruising flight more than 3,000 feet above the surface
, you must comply with the VFR cruising altitude rule.
How are Mocas depicted on an aeronautical chart?
The MOCA is listed below the MEA and indicated on AeroNav Products charts by
a leading asterisk
(e.g., “*3400” – see Figure 1-2, V287 at bottom left) The minimum reception altitude (MRA) identifies the lowest altitude at which an intersection can be determined from an off-course NAVAID.
Where can you obtain altimeter setting information?
Current altimeter settings must be obtained from
direct‐reading instruments
or directly from weather reporting stations.
What should the altimeter be set to before flight?
The minimum safe altitude of a route is 19,000 feet MSL and the altimeter setting is reported
between 29.92 and 29.43 “Hg
, the lowest usable flight level will be 195, which is the flight level equivalent of 19,500 feet MSL (minimum altitude (TBL ENR 1.7-1) plus 500 feet).
How is altimeter setting determined?
Altimeters
measure height above particular pressure levels
. To do this, they compare the pressure of outside static air to the standard pressure of 29.92′′ Hg of air at sea level. Air is denser at sea level than aloft, so pressure decreases as altitude increases (and vice versa).
What is the cruising altitude?
According to USA Today, the common cruising altitude for most commercial airplanes is
between 33,000 and 42,000 feet
, or between about six and nearly eight miles above sea level. Typically, aircraft fly around 35,000 or 36,000 feet in the air.
What is VFR altitude?
VFR cruising altitude rules in the US and Canada
On a magnetic course of 0-179 degrees shall fly at an
odd thousand ft MSL altitude +500 feet
(e.g., 3,500, 5,500, or 7,500 ft); or. On a magnetic course of 180-359 degrees shall fly at an even thousand ft MSL altitude +500 feet (e.g., 4,500, 6,500, or 8,500 ft).
What altitude and route should be used if the pilot is flying in IFR weather conditions and has two way radio communications failure?
A pilot experiencing two‐way radio failure at an assigned
altitude of 7,000 feet
is cleared along a direct route which will require a climb to a minimum IFR altitude of 9,000 feet, should climb to reach 9,000 feet at the time or place where it becomes necessary (see 14 CFR Section 91.177(b)).
How is flight level determined?
In the flight levels, the altitude is set by reference to a standard barometric pressure of 29.92 so as to create a standard reference for all aircraft and avoid any variation. The plane’s altitude is largely
determined by traffic en route
and the only thing in aviation that’s free—the wind.
What does a high altimeter setting mean?
When the temperature is warmer than standard
, you are higher than your altimeter indicates. When you are flying above a location for which you obtained a local current altimeter setting in extremely cold temperatures, the true altitude of the aircraft can be significantly lower than indicated.
How do you calculate pressure altitude?
To calculate pressure altitude without the use of an altimeter,
subject approximately 1 inch of mercury for every 1,000-foot increase in altitude from sea level
. For example, if the current local altimeter setting at a 4,000-foot elevation is 30.42, the pressure altitude would be 3,500 feet: 30.42 – 29.92 = 0.50 in.
How do planes stay at the same altitude?
As they get a faster airflow at the top, and as the air accelerates down the wing, it generates a
lift force
in the opposite direction that then enables the plane to move upwards, and also to maintain altitude. The more air that the aerofoil deflects, the greater the lift force.
What are the types of altimeter?
- Barometric altimeter.
- Radio altimeter.
- GNSS (GPS, Galileo, etc).
- Laser altimeter.
What unit is altitude measured in?
The primary unit of measurement of altitude and elevation or height is
the metre
. However, the most widely used unit of measurement in aviation is the foot. Metric altitudes and flight levels are used in certain countries.
What is the difference between altitude and flight level?
In its general term, altitude can be defined as an aircraft’s vertical
distance
above a fixed datum, typically the ground level or sea level. … Flight Levels refer to an aircraft’s vertical distance referenced to a standard air pressure datum instead of the real altitude above the ground or sea level.
What does IFR mean in aviation?
Description.
Instrument Flight Rules
(IFR) are rules which allow properly equipped aircraft to be flown under instrument meteorological conditions (IMC). IFR are detailed in ICAO Annex 2: Rules of the Air, Chapter 5: Instrument Flight Rules.
How do you calculate distance to descent?
A quick and easy way to figure it out is to
start with your altitude above field elevation and multiply that number by three
. This will give you the approximate distance in nautical miles from the airport to start a 500-foot-per-minute descent in the typical light general aviation airplane and reach pattern altitude.
What is the rule for VFR cruising altitudes regarding direction of flight?
VFR-ON-TOP CRUISING LEVELS FOR YOUR DIRECTION OF FLIGHT ARE:
more than 3,000 feet above the surface to FL 180: ODD/EVEN ALTITUDES/FLIGHT LEVELS PLUS FIVE HUNDRED FEET
.
What is a contact approach IFR?
A contact approach is
an approach available to aircraft operating on an IFR flight plan
, where the pilot may deviate from the published instrument approach procedure (IAP) and proceed to the destination airport by visual reference to the surface.
How do you do a vot check?
- Tune your VOR to the VOT signal.
- Set the course selector to 0 degrees, and the track indicator should be centered.
- The TO-FROM indicator should read FROM.
- Next, set the course selector to 180 degrees.
What is the standard altimeter setting?
The standard altimeter
29.92 inches Mercury (“Hg.)
setting at the higher altitudes eliminates station barometer errors, some altimeter instrument errors, and errors caused by altimeter settings derived from different geographical sources.
What cruising altitude is appropriate for a VFR flight on a magnetic course of 135?

Which VFR cruising altitude is appropriate when flying above 3000 feet?
Which VFR cruising altitude is appropriate when flying above 3,000 ft AGL on a magnetic course of 185?
odd thousand plus 500 ft altitude while on a magnetic course of 0-179
. How should a VFR flight plan be closed out at the completion of the flight at a controlled airport?
Why is altimeter setting important?
Weather changes
that affect temperatures and air pressures cause the complications in understanding and using an altimeter. This is why an aircraft’s actual height above mean sea level is its true altitude while what the altimeter says is the indicated altitude. … Before going flying, you have to set the altimeter.
How a pressure altimeter works to determine and display aircraft altitude?
The altimeter measures the height of an aircraft above a fixed level. The instrument senses this by
taking the ambient air pressure from the static port
. … Inside the altimeter is a sealed disc called an aneroid, or bellows. As the aircraft goes up, the pressure inside the case decreases and the bellows expand.
What is the go around procedure?
The procedure is
to retract the flaps immediately to 20 degrees and then go for climb airspeed
. … Once the aircraft has cleared the obstacle and has adequate speed, then retract the rest of the flaps.
How do you set the altimeter on Microsoft Flight Simulator?
You have to tune to ATIS for the local airport and get the correct barometric setting for your altimeter. You can cheat by
pressing the “b” key on the keyboard
though as this is the keyboard shortcut mapping to set it automatically.
Does altimeter show MSL or AGL?
A plane that flies at 10,000 feet MSL and stays level registers as flying at 10,000 feet MSL — no matter the terrain changes below the pilot. Pilots use altimeters, which
measure the AGL
, when the aircraft is flying at relatively low heights landing at an airport.
How does the altimeter measure altitude?
An altimeter is a device that measures altitude—a location’s distance above sea level. Most altimeters are barometric, meaning they measure altitude by
calculating the location’s air pressure
. … They determine altitude by measuring air pressure. As altitude increases, air pressure decreases.
How should you preflight check the altimeter prior to IFR flight?
The indication should be within 75 feet of the actual elevation for acceptable accuracy. How should you preflight check the altimeter prior to an IFR flight? b)
Set the altimeter first with 29.92′′ Hg and then the current altimeter setting
. The change in altitude should correspond to the change in setting.
What altitude do prop planes fly at?
A small single-engine propeller airplane like the popular Cessna 172 can fly up to
15,000 feet
. Since these airplanes mostly unpressurized airplanes, they cruise mostly cruise below 10,000 feet. A small business jet can fly up to 45,000 feet and cruises at 41,000 feet.
What altitude do private jets fly at?
A private jet can fly at a height of
up to 45 000 ft
, though most cruise at 41 000 ft. This is generally higher than an airline flight and allows for a more direct route – out of the most congested area of the sky. A private jet pilot will choose the optimum cruising altitude depending on the distance of the journey.
What is the hole in the back of an airplane?
The small hole you see on the back of airplane tails is
part of the auxiliary power unit
. Like other auxiliary power units, it’s designed to produce power for airplanes. With that said, it doesn’t actually help airplanes produce propulsion.
