hello community I’m a I.F player since oct 2024 currently in grade 4 , trying to be better in 2025 as of now I’m more experienced in flying with the plan and following atc instruction but theere are some thing i want ask to make my flight more realistic
REGARDING AGL ALTITUDE
so when the airport above sea level like 2000,3000 ft or more than that then,what we see (AGL or MGL ) to follow procedure like retracting flaps and turning off landing light or turning on during landing and reducing speed below 260 knots procedure …im bit confused when shift in seeing altitude
how to avoid steep descent from simbrief like to make it more relastic
cuz there been case when sim brief when it give landing fpl including 90 degree turn but at higher altitude and with obviously with higher speed
i have many question but it is not coming in my mind i might ask in future , I hope someone guide me about my this curious question , thank you…
What I usually do when high altitude airports is that I add 10,000ft to the airports altitude and at that altitude is when I turn on/off the landing lights and I maintain speed below 260kts, which irl I think the maximum is 250kts.
The ASL altitude, which is Above Sea Level, is often used for altitudes on the SID’s and STAR’s, as well as for the airport elevation (the airport and procedures data are always in Sea Level Altitude). However, for aircraft and ATC operational procedures, you must use the airport’s MSL as reference, since restrictions are based on the AGL (Above Ground Level) alt.
You must not exceed 250kts below 10,000ft AGL.
Let’s go for an example: Mexico City’s International Airport (MMMX)
Airport elevation: 7,300ft
250kts restriction: 17,300ft (That would be 10,000ft AGL, which is the restriction)
Regarding Flaps and Gear, is not quite based on the Altitude, but rather on the distance to the runway, and the speeds. However, you should have configured your aircraft for landing (flaps full, geard down, spoilers armed), entirely, when at 5nm from touchdown.
In real life, pilots set the airport’s Altimeter / QNH, which is the atmospheric pressure at a mean sea level. The cabin will indicate the altitude from 0ft on ground, based on airports elevation.
