What is minimum IFR altitude?

In a DMA, the minimum altitudes for IFR flight (explicitly defined in 14 CFR §91.177) must be 2,000 feet above the highest obstacle within a horizontal distance of 4 nautical miles from the course to be flown.

How do you find the minimum IFR altitude?

minimum IFR altitude

  1. i. In a designated mountainous area, 2000 ft above the highest obstacle within a horizontal distance of 5 statute miles from the course to be flown.
  2. ii. In other than mountainous areas, 1000 ft above the highest obstacle within 5 statute miles from the course to be flown.
  3. iii.

What altitude does IFR start?

When the prescribed minimum altitude for IFR operations is at or above 18,000 feet MSL and the atmospheric pressure is less than 29.92”, add the appropriate adjustment factor from TBL 4-5-3 to the flight level equivalent of the minimum altitude in feet to determine the adjusted minimum flight level.

What is minimum safe altitude MSA for IFR conditions?

The Minimum Sector Altitude (MSA) is the lowest altitude which may be used which will provide a minimum clearance of 300 m (1 000 ft) above all objects located in the area contained within a sector of a circle of 46km (25 NM) radius centered on a radio navigation aid.

What is the minimum altitude that is prescribed for off Airways IFR flights over mountainous terrain?

The AMA is the lowest off-airway altitude to be used under instrument meteorological conditions (IMC) that will provide a minimum vertical clearance of 1,000 feet (AGL), or in designated mountainous terrain 2,000 feet above all obstacles located in the area specified, rounded up to the nearest 100 foot increment.

What is the minimum safe altitude?

(c) Over other than congested areas – An altitude of 500 feet above the surface except over open water or sparsely populated areas. In that case, the aircraft may not be operated closer than 500 feet to any person, vessel, vehicle, or structure.

What minimum equipment is required for IFR flight?

In the United States, instruments required for IFR flight in addition to those that are required for VFR flight are: heading indicator, sensitive altimeter adjustable for barometric pressure, clock with a sweep-second pointer or digital equivalent, attitude indicator, radios and suitable avionics for the route to be …

What is the highest VFR altitude?

VFR cruising altitude rules in the US and Canada

In the US, there are specific VFR cruising altitudes, based on the aircraft’s course, to assist pilots in separating their aircraft while operating under visual flight above 3,000 ft above the surface (AGL) but below 18,000 ft Mean Sea Level (MSL).

What is the proper phraseology to say the altitude 10000?

Confusing Phraseology

‘ Phraseology contributed to this incident.” “To correct future problems like this, the altitude should be given in the form of ‘ten thousand’ or ‘eleven thousand’, instead of saying ‘one-zero’, or ‘one-one-thousand. ‘ There is too much of a chance of error.

At what altitudes do the cruising altitude orders come into effect?

Designated Cruising Altitudes are required for flights operating at more than 3,000 feet Above Ground Level (AGL). When a pilot is operating at more than 3,000 feet above the surface, they are to fly at an altitude appropriate for their direction of flight.

Can a student pilot fly into Class B airspace?

Generally, student and recreational pilots are not permitted to fly in Class B airspace, or to take off or land at a Class B airport. … The training and endorsement are good for a specific Class B airport only.


is MSA AGL or MSL? The MSA provides 1000 feet of obstruction clearance within the circle within 25NM of the fix. This is an MSL altitude hence the “altitude” in the Minimum Safe Altitude. If it was agl I would suspect they would say “height”.

What is MCA in aviation?

Minimum Crossing Altitude (MCA). An MCA is the lowest altitude at certain fixes at which the aircraft must cross when proceeding in the direction of a higher minimum en route IFR altitude.

When on a VFR on top clearance the cruising altitude is based on?

When must a pilot fly at a cardinal altitude plus 500 feet on an IFR flight plan? A) When flying above 18,000 feet in VFR conditions. B) When assigned a VFR on Top clearance.

What is the difference between MEA and MOCA?

Both the MEA and MOCA provide the same obstruction clearance. The only differ- ence is that radio navigation signal coverage is provided along the entire airway segment at the MEA, but the MOCA provides radio navigation signal coverage only within 22 nautical miles of the VOR.
